Our specimens are small, none reaching- the length of one inch, 

 and they are more depressed than any Mediterranean specimens 

 which have come under our notice. 



They were found at the Island of Madeira. 



185. PACHYGRAPSUS CRASSIPES Randall, 



Pachygrapsus crassipes Randall, Jour. Acad. Nat. Sci. Phila., viii, 127. 

 Stimpson, Crust. Pacif. Coast N. A., p. 27. 



Taken by us at Simoda, Japan. I am unable to find a distinguish- 

 ing character, however minute, between the specimens from Japan 

 and those from California. 



186. PACHYGRAPSUS SIMPLEX ' Stimpson 



Goniograpsus simplc.v Dana, U. S. Exploring Expedition, Crust., i, 344, 



pi. XXI, fig. 8. 

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



[48], 1858. 



Our specimens of this species were taken at Aladeira. They 

 agree exactly with those of Dana, who gives, with a doubt, Rio 

 Janeiro as the locality of his specimens. But they were probably 

 also from Madeira, as the U. S. Exploring Expedition stopped at 

 that island several days before proceeding to Rio. 



187. PACHYGRAPSUS INNOTATUS= Stimpson 



Goniograpsus innotatus Dana, U. S. Expl. Exped., Crust., i, 345, pi. xxi,

148], 1858. 



Our specimens agree in every respect with those of Dana, except 

 in the more rugose carpus.
