VERTIGO ROWELLI (Newc.). P. 143. 



Two specimens from Oakland, type locality, measure : 



Length 2.8, diani. 1.4 mm. ; nearly 6 whorls. 



Length 2.48, diam. 1.3 mm. ; 5y 2 whorls. 



The minute costulation is rather pronounced on the penult 

 whorl. The low, rounded rib-striae are about as wide as their 

 intervals. On the last whorl they become weak, more and 

 irregularly spaced. The long, convexly tapering spire is 

 rather turrited. 



VERTIGO OSCARIANA St. P. 144. 



Found at Ft. Lauderdale and Brickell's hammock below 

 Miami by Geo. H. Clapp.

VERTIGO THIBETICA (Bens.). 



Pupa thibetica Bens. (vol. xxiv, p. 138) has been placed in 

 Vertigo by Westerluud ; as it is in the Palaearctic fauna, and 

 is said to be smooth, translucent and glossy, this reference is 

 probably correct. It has not been figured. 



VERTIGO PUSILLA mut. ALBINA Taylor. Shell translucent- 

 white. Found with the typical form at Portsalon, near Let- 

 terkenny, Donegal County, Ireland (J. W. Taylor, Joum. of 

 Conch., vii, 1893, p. 194).
