This species, in life, has the cavap^x light brownish yellow or pale 

 brown, marked irregularly with brownish black bands and streaks. 



Two adult specimens were taken in 1898 ; Mr. Goode also obtained 

 one example. West Indies. 



A closely related form ( C occideyitalis St.) considered identical by 

 Kingsley, occurs on the west coast of America, from Cape St. Lucas 

 to Chili.

Miss Rathbun refers one young specimen to this species with some 

 doubt (coll. 1898). Bahamas, — Rathbun.

Miss M. J. Rathbun identifies the very common Bermuda Sesarma 

 as this species. It is doubtless listed by Mr. Rankin and others as 

 S. cinerea. Whether the true S. cinerea is also found there is 

 doubtful. Our numerous examples all appear to be of one species, 

 though they vary much in color. Common on the shores under 

 stones and among dead algae, nearly up to high-tide mark.
