ARNOLD] FOSSIL MOLLUSKS FROM CALIFORNIA 433 



anteriorly, sculpture consisting of moderately sharp raised spiral 

 lines, the penultimate whorl in the type carrying 9, 5 anterior to the 

 angle and 4 posterior, the latter being slightly less prominent than 

 those in front ; the raised lines become more prominent on the ante- 

 rior portion of the body, where they are wider spaced and the alter- 

 nate ones are relatively more important ; faint lines of growth, 

 convex posteriorly on the angle and concave posteriorly on the 

 posterior portion of the whorl, record a very wide, shallow notch as 

 having been present in the lip. Suture slightly undulating, often 

 prominent, owing to appressed portion of whorl being elevated 

 slightly into a faint ridge just anterior to suture. Aperture narrow 

 pyriform ; canal very short and broad and only very slightly curved. 

 Inner lip straight and smooth except for a single faint spiral ridge. 



Dimensions. — Altitude, 24 mm.; latitude, 12.3 mm.; altitude of 

 body whorl, 20 mm. ; longitude of aperture and canal combined, 16 

 mm. ; latitude of aperture, 5 mm. 



Notes. — This variety is closely allied to the typical B. car pent er- 

 iana, but in the series of specimens examined is constantly smaller, 

 relatively much shorter, and has the whorls more angulated than in 

 the typical form. Named for the Fernando formation, of which it 

 appears to be characteristic. 



Type.— Cat. No. 165,303, U. S. N. M. 



Locality. — Graciosa Ridge, near Folsom well No. 5, Orcutt, 

 Santa Barbara County, California ; locality No. 4476. 



Horizon. — Fernando formation, Pliocene portion. 



CANCELLARIA CRAWFORDIANA Dall, var. FUGLERI, new variety 



PI. LIV, fig. 9 



Description. — Shell averaging between 20 and 25 millimeters in 

 altitude, quite narrowly oval in outline. Spire elevated, and usually 

 consisting of 5 or 6 whorls in addition to the body whorl. Whorls 

 evenly convex and prominently angulated above, the portion of the 

 whorl posterior to the angle forming a narrow revolving table. The 

 surface of the whorls is cancellate, the sculpture consisting of narrow, 

 rounded, raised revolving ridges (9 on the penultimate whorl, 18 on 

 the body whorl in the type) and longitudinal ribs of the same char- 

 acter (23 on the penultimate whorl of the type) and prominence as 

 the revolving ridges. Suture deeply appressed and distinct. Aper- 

 ture ovate, canaliculated in front (the canal is broken off in the type). 

 Columella with two prominent oblique plications. 



Dimensions. — Altitude of imperfect specimen (type), 22 mm.;
