WEST AMERICAN HALIOTIS — BARTSCH 57 



HALIOTIS CRACHERODII CALIFORNIENSIS Swainson 



1823. Ealiotis californiensis Swainson, Zool. Illus., ser. 1, vol. 2, pi. 80. 

 1900. Ealiotis honita Okcutt, West Arner. Sci., vol. 10, p. 30. 



This is the subspecies with the small and numerous perforations. 

 Our large series of specimens from Guadalupe Island agree perfectly 

 with Swainson's figures, and they are the only ones that absolutely 

 satisfy them. I therefore believe that the type locality for H. 

 calif omiensis is Guadalupe. 



The type of Orcutt's Ealiotis honita, U.S.N.M. No. 1C2008, bears 

 on its label "near Santa Barbara, California," but in his description 

 he adds, after citing Santa Barbara, "It is evidently rare and may be 

 from Mexican waters." 



I agree with this last statement for it undoubtedly came from 

 Guadalupe Island. 



In addition to the living species referred to above, the following 

 fossil Haliotis have been described from California : 



HALIOTIS LOMAENSIS F. M. Anderson 



1902. Haliotis lomaensis F. M. Anderson, Proc. California Acad. Sci., ser. 3, 

 Geology, vol. 2, p. 75, pi. 9, fig. 183. 



Dr. Anderson described a specimen from the Cretaceous of the 

 lower Chico bed of San Diego County, Calif. 



The type is No. 65 of the California Academy of Sciences Inverte- 

 brate Paleontological collection. 



HALIOTIS PALEA Woodring 



1931. Haliotis palea Woodring, Journ. Pal., vol. 50, pp. 38, 39, pi. 6, figs. 1-3. 



This species comes from the Miocene of the south slope of Santa 

 Monica Mountains, south end of the ridge along the east side of 

 Brown Canyon, Los Angeles, Calif. 



The type is No, 1206 in the California Institute of Technology. 



Dr. Woodring considers this related to Haliotis comigata Gray, 

 with which I agree. 



HALIOTIS LASIA Woodring 



1932. Haliotis lasia Woodring, Proc. U. S. Nat. Mus., vol. 81, pp. 1-4, pi. 1. 



This species was described by Dr. Woodring from the Miocene of 

 Temblor Range, San Luis Obispo County, Calif. 



The type, U.S.N.M. No. 371767, and 19 paratypes, U.S.N.M. No. 

 371768, are listed. 



Dr. Woodring considers this most nearly related to Haliotis fulgens 

 Philippi.
