It differs from that species in possessing a prominent spine on the upper side of the head, in having stouter first antenna with fewer segments in the flagellum, and in having broader gills.

AMPHIPODS 245 This species agrees closely with Caprella drepanocheir Mayer in the general form of the body, the peculiar character of the second gnatho- pods of the male, the form and armature of the posterior perseopods.

The absence of a spine near the upper end of the palm of the second gnathopods of the male may not be a distinction of much importance, as older specimens of drepanocheir than those which Mayer obtained (he had but four specimens, all males) might show the same feature. In view of the great variability of the species of Caprella, I do not feel entirely confident that this species may not ultimately prove to be but a variety of the one described by Mayer; but one has to dispose of it somehow, and calling it a variety of the latter involves the assumption that the two will be found to be connected by intermediate forms. So far as can be determined at present, the two species are quite distinct, and until the contrary is proved it will, I be- lieve, be best to designate this form by a respectably brief binomial. CAPRELLA KINCAIDI sp. nov. Type from St. Paul, Pribilof Islands, Alaska (six male specimens col- lected by T. Kincaid). Body stout, scabrous, and spiny above. Head much deeper than long, armed above with a pair of large spines in front of which is a prominent. Fig. 127. Caprella kincaidi. median spine. First thoracic segment much deeper than long and armed above with two pairs of spines; the three following segments of the thorax.
