THE CANCROID CEABS OF AMERICA 321 



Measurements. — Male (14970), length of carapace 23, width of 

 same 34.2, fronto-orbital width 16, width of front 9.2 mm. 



Range. — From Prince William Sound, Alaska, to Monterey, 

 California. Lower California (A. Milne Edwards). ^^ 



Habitat. — Low tide, among rocks. 



Variety. — A distinct variety has the carpus of the cheUpeds very 

 rough with irregular granulated tubercles, some coalescent; the 

 carpus approaches that of L. diegensis in which, however, the tubercles 

 are smoother and more finely granulate. In bellus variety, the carpus 

 of the ambulatory legs is bilobed above and the propodus of the last 

 three pairs has a similar, smaller lobe on its dorsal margin ; the lobes 

 are compressed and different from the thick, naked lobes on the carpus 

 of diegensis. Miss Stevens vvrites from Friday Harbor of the speci- 

 mens of this variety submitted that they were dredged in from 18 to 

 40 fathoms and that a few similar specimens have at times come up 

 in the dredge; that typical bellus is more common and occurs under 

 rocks along shore and occasionally is dredged.
