Coast Ranges of central California south to Santa Bar- 

 bara Islands and northern Baja California, where several 

 nominal subspecies are recognized as follows :

Pupa californica catalinaria Sterki, Naut., IV, 1890, p. 8. 



*Santa Catalina Island (H. Hemphill) fide Sterki. 



Vertigo californica diegoensis (Sterki). 



Pupa californica diegoensis Sterki, Naut., IV, 1890, p. 18. 



*San Diego, (H. Hemphill) fide Sterki; San Ramon, lat. 

 30 deg. 45 min., fide Pilsbry. 

 Vertigo californica elongata (Sterki).

Fig. ; Sterki, Naut., XXI, 1907, p. 90, PI. XI, fig. 5. 



Pilsbry (loc. cit. p. 133) has regarded this as a subspecies 

 of Vertigo modesta Say, a widespread western species in the 

 Canadian Zone. 



Canadian. 



*Bluff Lake, (S. S. Berry, Miss N. G. Spaulding) fide 

 Berry, Cienaga west of Green Valley, (S. S. Berry) fide Berry; 

 cienaga, alt. 7,500 feet. New England Trail, San Bernardino 

 Mountains (S. S. Berry) fide Berry. 



Vertigo ovata (Say). 



Fig. ; Binney, Manual, 1885, p. 333, fig. 362-363. 



Reported by Orcutt from San Diego south to lat. 31 deg. 

 The species is found in Arizona and New Mexico, but its occur- 

 rence in California has not been confirmed. 



Vertigo rowelli (Newcomb). 



Fig.; Pupa Rowelli Binney, Manual, 1885, p. 156, fig. 139. 



Cooper records "Pupa" rowelli and "Comulus" fulvus 

 from the vicinity of San Gorgonio Pass, San Bernardino Moun- 

 tains, collected by Voy. It is probable that V. occidentalis or 

 some associated Canadian Vertigo was intended. 



CIRCINARIDAE.
