focussed. The first and second telopodite joint bear only few tactile bristles; the terminal joint has more, and on the median side several brush-like bristles as well. The basal part of these bristles is darkcoloured, and enters somewhat into the chitinous pad bearing the bristles. The colour changes abruptly. The terminal part is pale, somewhat irregularly arcuate, first blunt and smooth, then beset with dense, fine hairs, all directed medially, and form an exquisite cleaning organ for the antennae and the tarsi (fig. 435).

Second maxillae (text-figs. 4, 5) with sternite and coxae weakly chitinised, colourless, the sutures visible with difficulty. The two halves are scarcely connected in the middle. Two condyles between coxa and trochanter, one ventral and one dorsal. The telopodite is 5-jointed, and consists of a very short trochanter and four joints of the same size, praefemur, femur, tibia, tarsus. The praefemur (fig. 438) has a little prominence on the under side near the base. It seems to be the opening of a gland; the mass of this gland is visible in the interior of the joint close to the wall, distally and proximally to the opening. Praefemur with one dorsal spine, femur with four spines (dorsal, lateral, and ventral), tibia not spined, thus differing from Scutigera. The large spines are beset with little lateral points (text-fig. 5). Sternite and coxae of toxicognaths (text-figs. 6, 7) not coalesced. The sternite (v) is a small band embracing the whole base of the coxae. The dorsal wall of the coxa (Co) is much shorter than the ventral wall; the free margin of the dorsal wall is arcuate. The two dorsal walls are connected by a bridge (text-fig. 6, b). Verhoeff, in Bronn's Class. u. Ordn., Taf. iii, fig. 6, indicates this bridge as sternite, and does not draw the true sternite. The margin of the coxa bears four movable spines based on little protuberances, corresponding to the teeth of other Chilopods. The median tooth has little round tubercles. On the dorsal and ventral surface of the coxae are some tactile bristles. The condyles (2) are situated on the lateral side. The trochanter is an independent short joint. No condyle between trochanter and praefemur. Between praefemur and femur one dorsal and one lateral condyle, between femur and tibia and between tibia and tarsus one lateral and one ventral condyle. The praefemur below bears one large movable seta springing from a little protuberance (text-fig. 8). All the joints have numerous tactile bristles. Ordinary fine hairs densely cover the under side of the tarsus. The suture between tarsus and ungulum is interrupted. before reaching the dorsal wall; thus these joints are partially fused. The first and second pairs of legs with short tactile bristles on prae

the second pair onwards with tactile bristles and hairs. On the distal margin of the tibia a circle of dense stiff hairs (fig. 437); the coxae

of all legs have one large seta and are densely covered with microscopical hairs in both sexes. The second tarsus with papillae (text-fig. 9)

on the joints, excepting the first four and the last one to three joints. Generally there are two papillae on each joint, but they increase in number on the posterior legs; the fourteenth pair bears six papillae

in two rows of three each on each joint; but there are also joints with 1+2, 2+2, 2+3, 3+3 papillae on the same tarsus. The row of papilla-bearing joints is not interrupted (in Scutigera these joints alternate). The first and second tarsus is densely covered with hairs and single tactile bristles.

The sharp keels, well known in all other Scutigeromorpha, are completely wanting in Scutigerina. This character, indicated by Silvestri, is the single one which permits identification of his description, which is insufficient in all other points. Though the keels are wanting, they are made up for by the disposition of the bristles and spines, arranged sometimes in longitudinal rows. The praegenital segment in the sense given by Heymons is well developed in both sexes, yet the genital segment itself is very rudimentary (text-fig. 10). Looking at a male from above (fig. 439), we see between the fifteenth segment and the telson (T. Tels) a short segment (Tp), the praegenital segment. On the ventral side this segment is much longer (vp, fig. 440); behind a transverse edge it is abruptly declivous, and the posterior surface formed by this declivity bears a little callosity with two low, pubescent, blunt cones, the gonopods. Behind this callosity a second similar one is visible, bearing two somewhat larger cones, the rest of the genital segment (fig. 443). On the dorsal side the genital segment is completely suppressed. The praegenital segment is almost. hairless dorsally; ventrally it bears numerous strong tactile bristles, and the above-described peculiar minute hairs arranged in pairs.

* Signifies one dorsal spine, no lateral, one ventral.

The tergite of the praegenital segment (Tp, fig. 441) of the female is broad, partially pubescent, and connected with the preceding tergite of the fifteenth segment by a broad, membranous, hairless strip continued round the whole segment and therefore visible also on the ventral side (sk, fig. 442). The sternite of the praegenital segment (v.pg) is long, rectangular, situated between the large coxae of the gonopods (cog). I agree with the interpretation of Verhoeff relative to these parts. The telopodite of the gonopods (telg) is 2-jointed;

the basal joints are coalescent in their basal half, and they are inserted in the posterior margin of the sternite and in the coxa. The shape is the same as in Scutigera, with a bundle of bristles on the inside of the basal joint and a row of twelve teeth on the inside of the terminal joint. The female genital aperture is completely concealed by the gonopods, which are directed backwards and overlap the whole genital segment; the rest of this segment merely forms the margin of the large transverse aperture.

The telson is the same in both sexes, and consists of a densely pubescent tergite (T.Tels) and two subanal plates( sa. Tels) connected by thin hairless membranes.
