ISOPODA. 13 



quite, since a high magnification shows it narrowly truncate, carrying two spines. 

 Each side also carries two spines just above the apex. 



The eyes are rather small, lateral. The first antennae have the third joint about 

 as long as the composite first and second, and the fiagellum of seven joints, most of 

 which carry sensory filaments. In the second antennae the ultimate joint of the 

 peduncle is slightly longer than the penultimate ; the fiagellum is rather long, 

 fifteen-jointed. The mouth organs are of the pattern characteristic of Cirolana. The 

 limbs are rather slender, not very strongly setose or spinose, the first gnathopods 

 being, as usual, discriminated from the succeeding legs by the position of the fifth 

 joint. The uropods, like the telson, have a fringing of fine spines and feathered setae ; 

 the inner apex of the peduncle is rather sharply produced about to the middle of the 

 broad inner ramus, which narrows apically and extends beyond the telsonic segment 

 and the narrower inner ramus. The integument is covered with scale-like markings. 



The length is 5 millims., with a breadth of about 2 millims. The specimen carried 

 several young ones, still enclosed in membranous capsules, but with the eyes already 

 visible. I hesitate about applying a specific name, whether new or old, to this small 

 < vigerous specimen. 



Locality : Deep water, south of Galle, depth up to 100 fathoms. 



Conilorpheus, n. gen. 



Onlv the male known. Both first and second antennas short. First maxillae 

 carrying four strong plumose setae on the inner plate. The maxillipeds having the 

 plate of the second joint furnished with hooked spines. The male appendix of the 

 second pleopods is attached far down on the inner ramus. The uropods have the 

 process of the peduncle very elongate and the outer ramus much smaller than the 

 inner. 



The body is almost cylindrical, with the basal segment of the short pleon covered 

 by the laciniated seventh segment of the peraeon. In the first pleopods the peduncle 

 is not longer than broad, and neither ramus is hard. 



The generic name refers to the combination of characters, here presented, partly 

 pointing to the genus Conilera and partly to the genus Eurydice, which takes 

 its name from the wife of Orpheus. The first maxillae, like those of Bathynomus, 

 show an unusual feature in carrying four setae instead of three on the inner plate, 

 and the laciniate border of the last peraeon segment is also uncommon in this family. 



Conilorpheus herdmani, n. sp. Plate II. (A). 



The head is produced into a narrow distaby widened process between the first 

 antennae ; its breadth is not much greater than its length. The second and third 

 segments of the parallel-sided peraeon are the shortest ; the first segment even at the 

 forward produced sides is not longer than the seventh, of which the postero-dorsal
