[Pupa californica] var. cyclops STERKI, Nautilus iv, June, 

 1890, p. 18. 



A paratype is figured. It is slightly larger than Dr. Sterki 's 

 type. ' ' Some specimens have no columellar lamella, and some 

 have a small palatal fold" (Sterki, in letter). 



29d. Vertigo californica elongata (Sterki). PI. 9, fig. 4. 



"A little smaller and generally more cylindrical than the 

 type ; a part are even long cylindrical having the appearance 

 of an Isthmia [Truncatelli'na,]. The coloration is somewhat 

 paler and the lamellae are well formed" (Sterki). 



Length 2.5, diam. 1.2 mm. ; 6 whorls. 



Length 2.25, diam. 1.1 mm. ; 5 l / 2 whorls. 



Length 2.1, diam. 1.2 mm. ; 5 whorls. 



California: San Clemente Island, Hemphill, type loc.

[Pupa californica] elangata STERKI, Nautilus iv, May, 

 1890, p. 8. 



Fig. 4 is from a paratype. The parietal lamella is de- 

 cidedly longer than in V. californica, entering deeply. From 

 the elongate form figured it varies, in the same lots, to much 

 shorter forms. Specimens from Santa Barbara are 2.3 to 

 2.4 mm. long, or even smaller, 2 to 2.25 x 1.15 mm. 



This race is intermediate between V. californica and V. c. 

 catalinaria. 



29e. Vertigo californica catalinaria (Sterki). PL 9, figs. 5, 6. 



' ' Small, rather short, pale horn colored ; shell thin, delicate ; 

 rib-like stria3 less numerous and relatively larger; the whorls 

 are less high, which gives the shell a different appearance. 

 All lamellae are present and well formed, especially the aper- 

 tural [parietal]" (Sterki). 



Length 1.75, diam. 1.05 mm. ; 5*4 whorls. 



California : Santa Cataliua I., Hemphill, type loc. ; also
