CALIFORNIA STALK-EYED CRUSTACEA. 61 



typically double, the lower cusp obscure; hands rounded above and fur- 

 nished with a lobe projecting inward at the intero-proximal portion of the 

 upper side; lingers black or dark brown. Abdomen in the male five-joint- 

 ed, the last segment rounded and slightly wider than the preceding one, 

 which is somewhat wider than long. Merus of the ambulatory legs acute 

 above; carpus with a bilobed crest; crest of the propodus often with a lobe 

 at the base; dactyls villous. Color purplish, the legs crossed with light- 

 colored bars. 



Found among rocks at low tide from British Columbia 

 to Monterey. Vancouver Island (Bate, Newcombe), 

 Puget Sound (Stimpson)! northern California! Monterey 

 (Stimpson, Lockington)! 



Locality. Length. Width. 



Puget Sound; male 19 mm. 26.5 mm. 



Puget Sound; female 15.75 mm. 22.5 mm. 

 Monterey; male, type of 



Hemphillii LOCK. 18.75 mm. 28 mm. 



Two specimens whose measurements are given by 

 Stimpson were .54 by .80 in. and .56 by .89 in. "Northern 

 specimens," says Stimpson, " are more transverse, 

 rougher, more pubescent, and more sober in coloration 

 than those found in warmer latitudes." Possibly speci- 

 mens of leucomanus or frontalis were confused with this 

 species. I have seen Lockington's type of Hemphillii 

 (No. 35) which is preserved in the collection of the 

 California Academy of Sciences. It is a typical bellus 

 and as strongly transverse and as rough as the specimens 

 I have seen from farther north. The specimen from 

 Lower California which is figured as L. bellus by A. 

 Milne-Edwards (1. c.) probably belongs to a different 

 species.
