analog, in having a smooth and finely granulate 

 carapace, reduced submesial frontal teeth, shal- 

 low anterolateral teeth, nearly plane sternum and 

 abdomen in males, and similar length-width 

 proportions in mature males. 



A Pleistocene record for C. hellicosus (USNM 

 372804) is represented by the distal two-thirds of a 

 propodal finger from a minor left chela of a large 

 crab from the upper San Pedro formation, Signal 

 Hill, northeast of Long Beach, Calif. (Rathbun, 

 1926). Size and tooth pattern of this specimen are 

 indistinguishable from the modern form.
