COMPLETE HAIG : EASTERN PACIFIC PORCELLANIDAE 93 



a juvenile specimen was recovered from a sand and mud substrate in 

 35 fathoms. 



Specimens in the Hancock Foundation series include ovigerous fe- 

 males taken in every month except April, May, September, and Oc- 

 tober; all of those months with the exception of September are ac- 

 counted for in the literature. 



Remarks: Porcellana cinctipes was originally reported to be from 

 the Sandwich (Hawaiian) Islands, an error evidently due to a con- 

 fusion of locality data ; the collector, T. Nuttall, took specimens at var- 

 ious points in western America as well as in the Islands. The first to 

 recognize the identity of Porcellana rupicola with P. cinctipes was 

 Ortmann (1897); all subsequent authors have followed him in citing 

 this common species as Petrolisihes cinctipes. 



An early confusion developed when Lockington (1878) included 

 specimens from Baja California and the Gulf of California under 

 Petrolisthes rupicolus. These records were probably based on two spe- 

 cies not yet described at that time, P. cabrilloi Glassell and P. sch?nitti 

 Glassell, respectively. This erroneous extension of the range of P. cinc- 

 tipes was cited by several subsequent writers. Extensive collecting has 

 revealed that the species apparently ranges no further south than 

 Santa Barbara (probably Point Conception) on the California main- 

 land, and the northern Santa Barbara Islands, San Miguel, Santa 

 Rosa, and Santa Cruz; records from more southern localities can be 

 safely disregarded. 



Most early British Columbia and Washington records of Petro- 

 listhes cinctipes are probably based on P. eriomerus Stimpson, for 

 there are no recent records of P. cinctipes from the east coast of Van- 

 couver Island or from Puget Sound (Hart, 1940 and personal com- 

 munication). These old records, which include Strait of Georgia, Bay- 

 nes Sound, and Victoria (Newcombe, 1893), Nanaimo and Hope Is- 

 land (Taylor, 1912), Esquimault Harbor (Spence Bate, 1866), Bare 

 Island (Lenz, 1901), and Puget Sound (Caiman, 1898), are tentatively 

 listed in this report under P. eriomerus. 



Not only was Porcellana cinctipes erroneously attributed to the 

 Hawaiian Islands, but it found its way inadvertently, as Porcellana 

 rupicola, into the fauna of New Zealand. Kirk (1878, p. 466) listed 

 it from Lyall Bay, Wellington, New Zealand. The following year ( 1879, 

 p. 396) he reported further on the specimen on which this record was 

 based, writing as follows: "A single specimen of this species was re- 

 cently obtained by myself at Lyall Bay, living apparently upon terms
