also has a big basal molar; the upper finger is more curved and 

 the teeth are vague. There is a row of rounded tubercles on the outer 

 surface of the lower finger and the proximal half of the outer surface 

 of the upper finger has three rows of rounded tubercles. 



The ambulatories are quite slender, the series decreasing in length 

 in the order 1, 2, 3, 4. Each has the merus, carpus and propodus lat- 

 erally compressed, the propodus having a reinforced articulation with 

 the dactyl; the dactyl is powerful, long, slender, tapered, with an 

 acuminate horny tip. 



The eyestalk is short and thick, with a calcareous covering and a 

 rounded tonguelike process that extends upon the dorsal surface of the 

 cornea and nearly conceals it ; the cornea is large, nearly as long as the 

 stalk, hemiovoid, set terminally with excellent visual range in all di- 

 rections except dorsally. 



The antennulae are large and fold transversely within the fossett. 



The antennae have a not very large, squarish, basal article, the 

 distal margin of which does not reach the orbital angle; the second 

 and third peduncular articles are short, cylindrical and lie within the 

 orbital sinus ; the flagellum is slender and when extended is about two- 

 thirds the length of the long diameter of the orbit. 



The external maxillipeds are nearly square, a little wider than high, 

 close-fitting ; the exognath is rodlike ; the ischium of the endognath is 

 subrectangular with its proximal margin oblique; the inner lateral 

 margins meeting. The merus is squarish, its distal margin nearly 

 straight, its inner lateral margins slightly truncate at the base of the 

 palp and visible, rounded below this, including the lower inner angle ; 

 the palp is short, three-jointed and very tapered.
