PART 1 GARTH : PACIFIC OXYRHYNCHA 323 



Atlantic species reported as occurring in the Pacific, but unsupported 

 by records within the last century: 



L. emarginata Leach, "NW coast of America," (Randall, 1839, p. 106, 

 as L. affinis) ; San Francisco, March, 1854, T. G. Cary, Jr. (Rath- 

 bun, 1925, p. 317). 

 L. dubia Milne Edwards, "Chile" [really Cuba, fide Rathbun], (Streets, 



1870, p. 105, as L. subspinosa). 

 L. spinosa Milne Edwards, Chile (Milne Edwards and Lucas, 1843, 

 p. 6; Nicolet, 1849, p. 128). (See also Garth, 1957, p. 31.) 

 Since there is uniform agreement among specialists as to the identity 

 of the specimens involved with the Atlantic species listed above, the 

 writer prefers to treat these cases as errors of provenience, rather than 

 to countenance the dislocations which their inclusion in the Pacific fauna, 

 even on an extralimital basis, would imply. Libiniaf verrucosa, Maz- 

 atlan (Lockington, 1877c, p. 64) is a nomen nudum.

 ILibinia setosa, Miers, 1886, p. 73. 



Type: Female holotype, length 52 mm, width 39 mm, one of two 

 females originally in the collections of the California Academy of Sci- 

 ences but no longer extant. In view of these circumstances, a male speci- 

 men from Santa Maria Bay, Lower California, Mexico, collected 

 August 11 and 12, 1932, by the Zaca, Loc. 27594, and belonging to the 

 California Academy of Sciences, is hereby designated neotype. 



Type locality: San Bartolome Bay, Lower California, Mexico; W. 

 J. Fisher, collector. 



Localities subsequently reported, with collectors: Lower California, 

 Mexico: Playa Maria Bay, A. W. Anthony (Rathbun, 1925) ; Abreojos 

 Point, G. D. Hanna, California Academy of Sciences (Rathbun, 1924c) ;
