148 Addis on E. Verrill, 



The eye is large, cylindric, with a separate ocellus (figs. 2a, 2e). 

 The margin of the carapace has a single marginal spine below and 

 close to the eye-socket, and a minute hepatic spine a little distance 

 back of and below the eye. 



Larger second chela is elongated, slightly swollen in the middle ; 

 the thumb is a little bent down; the palm is about one and one- 

 third times longer than the dactyl; the fingers are slender, bent 

 inward at the acute tips, which cross when closed ; inner edges 

 have three small obtuse denticles proximally. The left chela is 

 usually rather smaller. The carpus is about as long as the palm, 

 terete, gradually enlarged distally ; merus is about seven-eighths 

 the length of the carpus. 



The legs of the first pair are more slender ; the chela is not much 

 wider than the carpus ; its fingers are equal to or slightly longer 

 than the palm; the chela is four-fifths the length of the carpus; 

 the carpus is considerably longer than the merus, which is about 

 equal to the chela. The merus is cylindric, slender, and has a 

 small distal spine. 



The legs of the third pair are slender; the propodus is nearly 

 twice as long as the carpus and has a row of five slender spines 

 besides a longer and two smaller distal ones, all accompanied by 

 one or two hairs; carpus much shorter; distal angle spiniform. 

 hairy. Dactyl is slender, a little curved, acute ; sometimes with a 

 double tip (-fig. ic). 



The telson is rather narrow, elongated, subtriangular, width to 

 length about as 1 : 2.7, tapered regularly distally, with an acumi- 

 nate tip, ending in a small, sharp, narrow apex; each side of the 

 tip are three slender spines, the intermediate one about twice as 

 long as the inner and four times as long as the outer one. The 

 dorsal surface has two pairs of spines ; sometimes two couples, 

 side by side, anterior to the middle, one of each couple smaller; 

 and a pair of more slender ones near the distal end. Uropods are 

 long ; outer lamella wide, ovate, with a spine and an acute denticle 

 at the notch. 



Other specimens of similar size (probably males) have the first 

 and second pair of legs much longer (longer than the body), with 

 more elongated chelae. Otherwise they are similar to those 

 described above. 



The following note was made from living specimens: "Color, 

 in life, translucent grayish white, with numerous small, round
