HYPERIDEA. ^QQg 



closely applied to the surface of the head, and curved downward and 

 outward. The first segment of thorax mostly concealed by second ; 

 the second segment longer than seventh. The antennary area narrow 

 below and widening a little above. Abdomen terminates in a small 

 triangular obtuse segment. Coxae of three posterior pairs broad 

 lamellar and often folded over the venter when the animal is at rest. 

 No pediform termination to seventh pair of legs was observed. The 

 proportional length of the joints of the sixth pair of legs is very diffe- 

 rent from the same in the preceding species. 



Eyes, sepia brown. The two masses of pigment, of an oblong subu- 

 late form, had a reddish-brown colour, and became ochre-yellow after 

 death. Ciliations of caudal lamellae plumose; the largest of these 

 lamellae are not ciliated.
