Monterey (Stimpson); Santa Catalina Island! San

This beautiful little species is commonly found in 

 tide pools. It is abundant at Monterey and San Pedro 

 on rocky shores. 



Heptacarpus paludicola, sp. no v. 



Closely allied to incta. Rostrum slender, horizontal, about as long as 

 the carapace, armed above with 6-8 sharp, evenly spaced teeth, the last 

 tooth on the anterior fourth of the carapace; lower margin armed with 

 2-4 teeth on the distal third or two-fifths. Antennular peduncle reaching 

 two-thirds as far as the tip of the rostrum; basal spine extending beyond 

 the tip of the first joint; upper distal margin of the first basal joint armed 

 with a single spine at the outer angle. Antennal peduncle not reaching 

 the middle of the acicle; acicle oblong, slightly tapering, closely resem- 

 bling that of picta, and equalling the rostrum; flagellum as long as the 

 body. Anterior chelipeds not reaching the tip of the acicle; hand narrow; 

 palm fully as long as the carpus and about three times as long as wide. 

 Second chelipeds about reaching the tip of the acicle; first joint of the 

 carpus but little longer than the second, third and fourth subequal and 

 each longer than the first, about equalling the fifth and sixth combined, 

 fifth a little longer than the sixth and slightly shorter than the seventh;

 legs very slender; distal portion of the outer surface of the merus joints 

 armed with a row of spines; dactyls short, about one-fourth the length of
