 1858. 



Upon the anterior region of the carapax there are the usual two 

 series of setose pits extending on either side, from the base of the 

 eye to the middle of the lateral suture. Rostriform tooth acute, 

 prominent ; lateral teeth of front acuminated. Eyes stout, shorter 

 than the acicles ; cornea a little dilated. Apex of ophthalmic scales 

 elongated and slender. The greater cheliped reaches to the tips 

 of the walking feet; surface granulated and covered with a short 

 pubescence; inner margin with a deep sinus at the juncture of the 

 carpus and the hand and another at the juncture of the dactylus v/ith 

 the hand; carpus subtriangular, sparsely spinous above, with a 

 smooth strip in the middle and a spinose inner margin; hand broad 

 in the female, with a median, and marginal rows of subspiniform 

 granules larger than the rest; dactylus above armed v/ith a median 

 series of sharp tubercles. Small cheliped subtrigonal, hirsute, and 

 granulated ; carpus with a spinous edge and a longitudinal smooth 

 channel above; hand not spinous, but with a blunt carina running 

 from the base to the immovable finger. In both chelipeds the meros 

 is deeply excavated beneath, with the margins long-ciliated ; the right 

 margin spinose. Ambulatory feet hairy, but not spinose above ; 

 tarsi rather broad, not twisted, and armed with corneous spinules. 

 Color of alcoholic specimens reddish. General length of a male 

 specimen, 2.2 ; length of carapax, 0.6 ; breadth of front, measured as 

 usual, between the outer bases of the antennae, 0.3 ; length of greater 

 cheliped, 1.28 inches.

Eupagurus tricarinatus Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. 251 

 [89], 1858. 



Eyes rather remote from each other-, and pretty large and stout, in 

 length about equaling the peduncle of the antennae, but overreaching 

 the acicle ; cornea considerably dilated ; peduncle constricted at base. 

 There is no distinct median or rostriform point to the carapax, but 

 the bracteole or interocular plate of the ophthalmic ring is consider-
