Phoxocephalus pectinatus^ sp. n. (PI. XVI. figs. 1-6.) Epimeres of the person rather deeper than their segments ; third pleon-segment with the lower margin straight, the hinder slightly convex, and the hinder angle with the point rounded. Head with the hood slightly curved downwards; eyes round, dark, and large, especially in the male. Upper antennse with the first joint longer than the two next, its upper margin produced and the lower furred in the male ; flagellum 4-jointed, terminated in the male by a stiff seta as long as the whole antenna ; accessory appendage 4-jointed, reaching nearly to the third joint of the flagellum. Lower antennas in the male as in P. Holbolli, in the female with the second joint of the peduncle nearly as long as the first and third together ; flagellum 4-jointed, as long as the second joint of the peduncle. First gnathopoda rather smaller than the second ; epimeres distally expanded ; propodos distally contracted ; second gnathopoda with the epimeres rounded-oblong ; margins of propodos parallel ; in both pair the propodos is almost as long as the four preceding joints, the second, third, and fourth joints being very short. First and second perseopoda much as in P. Holbolli, but with the dactylus about three fourths of the length of the propodos.
