of intimacy with a large family of Petrolisthes elongatus. Upon a com- 

 parison with the foreign Crustacea in the Colonial Museum, I find it 

 to agree in every particular with a specimen contained in the collec- 

 tion lately received from Prof. Button of the University of California, 

 and labelled as above." Kirk's record was later repeated by Thomson 

 (1899, p. 190) and Bennett (1930, p. 255). Prof. L. R. Richardson, 

 Victoria University College, Wellington, believes (personal communi- 

 cation) that Kirk somehow confused his collections, getting one of the 

 P. ruptcola received from Prof. Button mixed in with the specimens 

 of Petrolisthes elongatus from Lyall Bay. 



Range: Queen Charlotte Islands, British Columbia, south to Santa 

 Barbara (probably Point Conception), California; San Miguel, Santa 

 Rosa, and Santa Cruz Islands off the California coast.
