CRUSTACEA XORTH PACIFIC EXPLORIA'G EXPEDITIOX II7 



They were found in clefts of the surf-washed rocks above low- 

 water mark at Funchal, ^Madeira. The remark with regard to the 

 reputed locality of the last species applies equally well to this. 



188. PACHYGRAPSUS L^VIMANUS ' Stimpson 



Pachygrapsus Icefiiiiaiius Stimpson, Proc. Acad. Nat. Sci. Phila., x, p. 102 

 [48], 1858. 



This species has much resemblance to P. iniiotafiis and P. rugu- 

 losus of the Atlantic shores, but the carapax is somewhat narrower 

 and smoother, the carpus nearly smooth, and the raised line on the 

 outer surface of the hand, parallel to its lower margin, is obsolete or 

 nearly so. The hiatus between the suborbital lobe and the front is 

 much wider and the basal joint of the antennae broader. The 

 ground color of the carapax is bluish-white, but this tint is almost 

 concealed by crowded transverse black lines and blotches. Feet 

 brownish. Beneath nearly white. Dimensions of the carapax in 

 a male: Length, 0.54; breadth, 0.65 inch. Proportion, i : 1.204. 



It was found among stones at half-tide in Sydney Harbor (Port 

 Jackson), Australia.

 Goniograpsiis plicatus D.\na, U. S. Expl. Exped., Crust., i. 343. 



A single specimen, a female, was found at Loo Choo. In this the 

 transverse plications are much more strongly marked than in speci- 

 mens from the Hawaiian Islands, particularly those on the superior 

 surface of the meros-joint of the posterior pair of feet.

 Colors in life: The carapax is bluish-gray, everywhere trans- 

 versely lineated and blotched with black; feet often reddish. 



This species was found in considerable numbers at Port Jackson, 

 Australia, running over the rocks at and above half-tide mark.
