We here record a second female, somewhat smaller than 

 the type, which has come to light in the sorting of past 

 seasons' collections. It was taken on April 12th, 1888, 7^ 

 miles east of North Cinque Island, Andaman Sea, in 490 

 fathoms.]

(J ? . This species differs from all the members of its own 

 section in the enormous development of the spines of the 

 anterior moiety of its lateral carapacial ridges, which are 

 extended beyond the level of the frontal margin as in the 

 species of Section 1, and from all the species of its genus in 

 its greatly degenerate organs of vision, which, besides being 

 somewhat reduced in size, have the cornece yellow and densely 

 opaque throughout. Both moieties of the lateral and the 

 posterior moiety of the sublateral ridges are thick, blunt, and 

 entire^ but all the other ridges are broken up into tubercles ; 

 the subdorsal ridge is represented by six spiniform tubercles 

 ■ — three on each division of the carapace — the dorsal by six, 

 of which two are behind the cervical groove and four in front 

 of it ; the latter have two closely-parallel rows of much 

 smaller tubercles between them and their fellows of the oppo- 

 site side ; a minute median spinule projects from the anterior 

 end of the gastric region over the gastro-rostral groove ; 

 between the anterior ends of the posterior moieties of the 

 dorsal and subdorsal ridges an oblique row of four rather 

 large granules bounds that portion of tlie cervical groove 

 posteriorly. 



With these exceptions the carapace is smooth and bears 

 between its anterior lateral ridge and the gastric region on 

 each side an miusually distinct low oval swelling. The 

 antennal spine is unusually small — scarcely half the size of
