CALLIOPIIDAE 163 The dorsal processes in novae-zealandiae, when seen in dorsal view, are not acute, scarcely subacute, but merely rounded. Pleon segment 3 is feebly carinate, and the carina not at all raised. Postero-inferior angles of pleon segments 1-3 ending in small acute points, that on segment 1 very small. Side-plate 1 oblong (cf. Chilton, 1920, fig. 1); none of the side-plates serrulate, or only very obscurely so. Hind margin of 2nd joint in peraeopods 3-5 feebly serrulate. Gnathopod 1, 6th joint subequal to 5th, tapering slightly distally, palm oblique, convex. Peduncle of uropod 3 produced on lower inner apex in a short process for the reception and support of the inner ramus (cf. ventral view given by Chilton, 1920, fig. 5). The inner ramus is not at all flattened, but triquetral in cross-section. The whole integument is covered with an exceedingly fine and regular pitting. The last character decisively separates novae-zealandiae as a species from the Ant- arctic species here described. On the other hand, these latter species all agree with the New Zealand species in the character of the peduncle and inner ramus of uropod 3. The triquetral shape of the inner ramus appears also in O. longimanus, Boeck (cf. Shoemaker, 1930, p. 88, fig. 37 e), but the prolongation of the peduncle seems to be very slight or even absent (cf. the same figure). These features are not utilized by Shoemaker in his discussion of the generic characters of Leptamphopus and Oradarea. Both appear to be absent in Lept- amphopus longimanus, Sars (= sarsi Vanhoff.), judging from Sars' pi. clxii (1895). Shoemaker includes in the genus the northern longimanus, Boeck, non Sars, and thus proposes the name walkeri for Walker's preoccupied "longimana"'. He also suggests that novae-zealandiae might be placed temporarily in Halirages. With the qualification "temporarily" I agree
