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 XL 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-ad; Plate H. 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. 



Antennulce. Absent. 



Antenrue. 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. 2 a) has been examined. The cut- 

 ting portion well developed, ending in five teeth ; the lacinia with about six 

 setae, and the cuspis lacinige large, with teeth of very different magnitude. The 

 molar process rather long and proportionally slender, seen from below (as in. 

 Fig. 2 a) 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 2 a 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. 



Maxillulce (Fig. 2 6). The distal part of the lobe of the first joint broader 

 and less curved than in the preceding species, hairy and without spine-like 

 setae ; the lobe of the third joint about as in Eurycope pulchra. 



Maxillos (Fig. 2 c). The lobe of the second joint distally proportionally 

 narrow and tapering towards the rounded apex, which is furnished with 

 normal hairs. 



Maxillipeds (Fig. 2 d). 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 Eurycope
