Cumacea: 20. Lampropidae, 1. Lamprops 155 



Pleou with telsou scarcely as long as preceding part of the body; telson 

 in 9 tapering considerably, with 2 pairs of small lateral spines and 5 spines 

 at apex, the middle one the shortest, outer pair longest, divergent; telsou 

 in (S little tapering, the small lateral spines far apart, of the apical spines 

 the long outer pairs subequal, little divergent. Eye small, distinct. An- 

 tenna 2 of <3 unusually short, plainly prehensile, proximal section of flagellum 

 thick with small hooklike projections of the medial margin. 2""^ peraeopod 

 nearly as long as the P^ its ?*•> joint considerably longer than the ^^^. In 

 peraeopod ?> of Q the rudimentary exopod is rather conspicuous. Peduncle 

 of uropods as long as the telson, longer than the exopod, which is much 

 shorter than the endopod. Colour brownish, mottled in front with opaque 

 white. L. Q 6 mm. <3 scarcely 5 mm: Alaskan specimens?, ovigerous 9

Pseudorostral lobes obtuse, scarcely projecting beyond the blunt antero- 

 lateral corners. Carapace with 3 pairs of obliquely curved ridges crossing 

 the branchial regions. First -i pedigerous segments combined longer than 

 the carapace. Pleon with telson longer than preceding part of the body. 

 Telson nearly twice as long as fi*^ pleon segment, rapidly tapering, with a 

 single pair of lateral spines, 5 apical spines, of which the divergent outer 

 pair and the central spine are much larger than the intermediate pair. Eye 

 conspicuous, dark red. Antenna 2 of d about half the length of the body, 

 not so conspicuously prehensile as in /.. fuscata. Peraeopod 1, 7*^ joint 

 shorter than 6ti». Peraeopod 2, 7*^ joint subequal to fi^h, 5*^^ equal to both 

 combined. Peraeopods 3, 4. 5 densely setiferous. Peduncle of uropods scarcely 

 longer than the telson or the exopod. in which the first joint is rather 

 shorter than the second: the endopod is rather longer, its P* joint longer 

 than the 2"'^ and 3*^ combined. A broad band of dark brownish violet crosses 

 the branchial regions and is succeeded by other transverse bands. L. 9 9 mm, 

 (5 considerably less.

Pseudorostral lobes truncate, not produced beyond the slightly projecting, 

 obtuse, sometimes denticulate, antero-lateral corners. Carapace with 4 pairs 

 of very distinct, arcuate, nearly parallel ridges, the first from antero-lateral 

 corners to the sides of the frontal lobe, the second extending l)ehind that 

 lobe from the lower margins, the third and fourth similarly, the fourth
