Habitat. Station 3361 (Lat. 6° 10’ N., Long. 83° 6’ W.), 1471 fathoms, 2 
specimens ; Station 3413 (Lat, 2° 34’ N., Long. 92° 6’ W.), 1360 fathoms, 5 
specimens, 
Remarks. This species is closely allied to Eurycope fragilis Bedd. (“ Chal- 
lenger ” Isopoda, p. 63, Plate XI. Fig. 8-12) ; but if the drawings of Beddard 
are trustworthy in detail, my species is easily distinguished from E. fragilis by 
the processes on the dorsal surface of the head, by the shape of the lateral 
margin of the three posterior thoracic segments, by the direction of the pos- 
tero-lateral abdominal processes, etc. However, a thorough revision of many 
of the “Challenger” Isopoda, especially of the Asellota (sens, lat.), is very 
much needed. 
2. Eurycope scabra, n. sp. 
Plate I, Fig. 2-2d3; Plate II, Fig. 1. 
Only one single and ill-handled female specimen is present ; yet I hope that 
the species can be easily recognized, especially by the aid of my figures. 
Head, thorax, and abdomen without any processes, and scarcely with sharp 
angles; but with the exception of a transverse belt across each of the four 
anterior thoracic segments, the dorsal surface of the body is almost wholly cov- 
ered with numerous granulations, so that it becomes scabrous in a much higher 
degree than the preceding species. 
Antennule. Absent. 
Antenne. Only the four proximal joints are present. The third joint with- 
‘out any process, but above at the exterior side is seen a small triangular and 
rounded exopod, well set off by a suture. 
Mandibles. Only the left mandible (Fig. 2a) has beéa examined. The cut- 
ting portion well developed, ending in five teeth; the lacinia with about six 
sete, and the cuspis lacini® large, with teeth of very different magnitude. The 
molar process rather long and proportionally slender, seen from below (as in 
Fig. 2a) almost conical with the end cut off very obliquely ; seen from in front. 
the distal part is somewhat broader, and the terminal face is vertical, with 
sharp serrulation and a few broad hairs; but in the lower end of the face a tri- 
angular process is seen, and it is this process which in Figure 2a overlaps the 
greater part of the end. The palp is very slender; second joint but a little 
longer than the first; the third very slender. 
Maxillule (Fig. 2b). The distal part of the lobe of the first joint broader 
and less curved than in the preceding species, hairy and without ‘spine-like 
sete ; the lobe of the third joint about as in Eurycope pulchra. 
Masilla (Fig. 2c). The lobe of the second joint distally proportionally 
narrow and tapering towards the rounded apex, which is furnished with 
normal hairs. 
Maxillipeds (Fig. 2d). Second joint rather elongate, its lobe with the 
terminal margin closely serrated and with about twelve coupling-hooks at the 
inner margin. Fourth and fifth joints more expanded than in Hurycope
