Miss Rathbun considers that Squilla, Fabricius, 1793, was preoccupied by O. F. Müller in 1776 for a genus of Amphipoda. But Müller's Squilla ventricosa is a synonym of Slabber's Phtisica marina, 1769, so that Squilla, Müller, cannot be upheld, and yet it does not seem reasonable that a name which had long been common property, as it were, should lapse through a casual misappropriation. Seba's Squilla mantis, vol. iii. of his Thesauri, 1760, sufficiently justified Fabricius in his own day, though now open to cavil, as coming from an authority not consistently binomial. 1902.

LYSIOSQUILLA CAPENSIS, Hansen.

Hansen gives a brief provisional description of this species by saying that it "is easy to distinguish from all others by its possessing 14 teeth besides the terminal one on the finger [of the raptorial claw], 7 spines on the uropod and a telson shaped as in Lysiosquilla maculata (Fabricius)." One specimen from Port Elizabeth in the Museum at Strassburg.

1843. G. c., Krauss, Südafrik. Crust., p. 60.

Krauss says: "According to the description by MilneEdwards in his Hist. nat. des Crustac., vol. ii., p. 528, the

specimens which I have brought home undoubtedly belong to this species which is distributed in all warm seas; with the illustrations known to me, however, some details do not quite agree. The little plate in the middle of the frontal margin and at the base of the eyes is broad, rounded at the corners and in the middle ending in a spine. The 6 rather long rounded prominences on the penultimate segment of the abdomen do not end behind in a long sharp spine, the 3 much larger prominences on the last segment are not armed with. marginal teeth and the gap on the hind margin is wider and in the middle incised. This species when alive is beautifully marbled in green and yellowish tints and violet on the prong of the raptorial feet. It is rather rare at Natal Point. Length 24 inches."

Mr. Lanchester supplies many bibliographical references and gives fifteen varietal names, among which his var. tumidus seems best to satisfy the description above translated from Krauss.

LARVAL SQUILLIDÆ.

GEN. ALIMA, Leach.

Giesbrecht gives as the leading feature of the Squilla (Alima) group of larvæ that the telson has four or more spines between the second lateral spine and the spine of the hinder angle.

GEN. ERICHTHUS, Latreille.

1817. Erichthus, Latreille, Le Règne Animal, vol. iii., p. 43. 1837. E., Milne-Edwards, Hist. Nat. Crust., vol. ii., p. 499. 1910. E., Giesbrecht, F. und Fl. Golfes von Neapel, vol. xxxiii., pp. 122, 148.

To distinguish Erichthus larvæ from the preceding Alima group, Giesbrecht states that they have only 1 spine between the second lateral spine and the spine of the hinder angle. It may be observed that examples of both these groups were obtained by Dr. Gilchrist in the Pieter Faure, but the discussion of the Alima-forms must be deferred. The genus Erichthus has been subdivided, so that for the larvæ of Lysiosquilla Brooks uses the term Lysioerichthus, which Hansen has modified, conveniently but perhaps not legitimately, into Lysierichthus.

Under the first reference the reasons are given for rejecting the older name Cumacea. Now that the generic name Cuma is abandoned, it would surely be well to avoid using it in fresh compounds. The history of the name gives it no great claim to sympathy, and, if it ever had one, it has been already almost over-employed in the formation of derivative names, such as Pseudocumidæ and Ceratocumidæ, for which should properly be read Pseudocumatidæ and Ceratocumatidæ. In Cuma, the Greek word for an embryo, Milne-Edwards seems to have embalmed his erroneous notion that these forms were all embryonic.
