This species might ]>erhaps be referred to Locking(ou'sc*Y'»»/a/«.s', ex- 

 cept that he describes the outer suiCacc of carpus and nuinus as 

 smooth. 



Gelasimus latimanus.. 



This species is represented by a single male specimen, found among 

 a huge lot of (h'laxintiisfjyaciliH from La Paz, Lower California, L. Leld 

 ing (17500), It differs from all described species except f/ibbostts, in hav- 

 ing the abdomen (ive segmented; and from (/ihhosK.s in the entirely dif- 

 ferent character of tlu^ hand and lingers which arc short and broad. The 

 carapace in general appearance resembles that of gracilis except that 

 it is broader and mu(;h more convex; it is smooth to the eye; front ;ind 

 orbits similar to those of firdcili.s; eyes shorter uiid stouter, h'irst seg- 

 ment of abdomen very short; second e(|ualing the tirst in length; 

 fourth, lifth, and sixth anchylosed, IMaxillipeds very convex, Laiger 

 cheliped short; inerus and carpus wi(h <Miter surface rugose, and inner 

 margin denticulate; pro])odus shorter than the width of the carapace; 

 l)idm bioad, outer surface closely set with distinct granules, which 

 become tuberculate near the upper margin; inner surfac-e with the 

 lower proximal jmrtion granulate, the distal portion smooth, the two 

 parts not sei)arated by a shar]) ridge; i)arallel to the b;ise oClhe dactyl 

 there are two lines of tubcr<'h!s, the ])osterior line continuous wi(h (he 

 granules on the edge of the pollex. Fingers granulate, much shorter 

 than the palm, broad, little gaping; the pollex rounding upwaiil, the 

 <liu-,tyl slightly arched and overreaching the pollex luit little, iSmaller 

 cheliped with jialm broad and fingers widely gaping, but not so mu<h 

 so as in gibbo.sus. And)ulatory legs with ;i few long haiis, especially 

 on the last three Joints, 



Length, 0.3; width, 10; length of dieliped alxuit 18 millimeters.
