1 specimen (mounted)." Length 9 mm.

"One specimen only of this form, a female, is found in the collection, mounted in Canada balsam on a glass slide. The specimen measures in length 9 mm." Sars further states that it "was obtained at the surface of the sea, in the following locality:-Date. December 14, 1873. Locality. South of Cape of Good Hope." It is evident that the same specimen is intended under the two different dates. The Challenger was in Simon's Bay from the 12th to the 17th of December, and on the latter date left the Bay for the southern cruise at 6.30 a.m.

As Anchialus, Kröyer, 1861, is the earliest of the five or six genera assigned to this subdivision of the family Mysidæ, it should be the foundation of the family name. Anchialus being preoccupied gives place to Anchialina, Norman and Scott, 1906.

A. typica

Hansen remarks: "A. truncata G. O. Sars G. O. Sars (not Kröyer) differs from the real A. typica Kr. in a number of features. The frontal plate is a little longer with the transverse, straight terminal margin; the eye-stalks seem to be shorter; the protruding part of the fifth joint of the male gnathopods is more removed from the distal end of the joint; the sixth joint of the first pair of the thoracic legs in the male is quite different, being divided into 3 subjoints with about 11 long, cylindrical setæ distributed along the distal two-fifths of the interior margin of the joint and on its end; the pseudobranchial plate of the male pleopods has the outer angle sharp and setose; finally the exopod of third pleopods (not fourth pair, as stated by Sars) is extremely different, resembling much more a normal ramus."

FAMILY MYSIDEÆ.

1910. Mysina, Hansen, Schizopoda, Siboga Exp., pt. 37, pp. 12, 62. Hansen subdivides this family or sub-family into four tribes, which he calls Erythropini, Leptomysini, Mysini, and Heteromysini. Cæsaromysis and Katerythrops are placed in the first of these groups, Leptomysis is in the second.
