lamina. As mentioned in the generic character the first maxilliped 

 has 110 flagellum to its broad curved exopod, thus differing from 

 ]'i/lnrJirli't*, A. Milne-Edwards, from tliat author's P/f/f //<//*..//'/. and 

 from Uroptychus, Henderson. On the other liaud, the third maxilliped 

 shows a striking likeness to that in the last-named genus, having its 

 sixth joint longer than any other. The third joint is fringed with 

 twenty-one teeth; the fifth, sixth and seventh joints are profusely 

 furnished with very long selae. 



If the detached limbs are correctly allocated (as suggested by the 

 bases of four pairs, these bases being still in attachment to the body) 

 the chelipeds are rather short and slender, the fifth joint very small, 

 the palm widening to the base of the much shorter fingers, which have 

 overlapping acute apices. The following peraeopods differ a little in 

 length and are nearly four times as long as the chelipeds, the fifth 

 joint about half as long as the fourth and two-thirds the length of the 

 sixth, all three slender with spinose margins, the finger very small, 

 curved and spinose. The fifth peraeopods as preserved are rather 

 obstinately folded, with the fifth joint about as long as the chela, of 

 which the small fingers are shrouded in a mass of long stiff setae. 



All the segments of the pleon, except the telson, are broad and to 

 some extent trilobed, with fringes of setae. The telson is somewhat 

 broader than long, faintly emarginate. The rami of the uropods are 

 oval, subequal, these and the telson being also fringed closely with 

 long setae. There were twenty-one large eggs firmly enclosed in the 

 pleou, with the fifth peraeopod directed backwards towards them. The 

 carapace has a length of 7 mm., with a breadth of about 6 mm.
