394 BULLETIN 152, UNITED STATES NATIONAL MUSEUM 



Color. — Carapace of freshly preserved specimens olive gray some- 

 times finely speckled on posterior half. Dorsal half of chelipeds 

 covered with reddish speckles more or less confluent; a larger red 

 spot at articulations. Legs with duller speckles like carapace. The 

 dark color of immovable finger may extenci in male along half, or 

 even more than half, of entire lower margin of propodus. 



Measurements. — Male holotype, length of carapace 9.4, width of 

 same 12.8, fronto-orbital width 7.8, width of front 4.2 mm. 



Remarks. — Small specimens are easily mistaken for Panopeus 

 bermudensis on account of the similarity of the granulate lines on 

 the carapace, but they can be identified by the character of the 

 lateral teeth, the thick front, the texture of the palms, and the exten- 

 sion of the color of the finger in the male.
