14 PALEONTOLOGY OF CALIFORNIA. 



L1TTORINA, Fer. 



L. R£mondii, n. s. 



PL 2, Fig. 23, 23 a. 



Shell small, conical, thick; spire elevated; whorls five, nearly 

 flat on the sides, subangulated at the base; suture impressed, 

 under side obliquely flattened. Aperture sub triangular; outer 

 lip simple; inner lip somewhat flattened, thickened, bordered 

 by a more or less marked rim, behind which is generally a faint 

 umbilical depression. Surface smooth, or marked by a few faint 

 spiral lines. The lower angle of the whorls is variable; some- 

 times it is roundly subangulated, and at others it is bordered by 

 a prominent thickened rib or band. 



Figures, magnified views of the two extreme forms. Length about half an inch. 

 Locality and position : From the Pliocene of Kirker's Pass. Found only in a 

 tingle bed, and collected by Mr. Esmond. 



TURRITELLA, Lam. 



T. HOFFMANNII, n. S. 

 PI. 2, Fig. 24. 



Shell large, many-whorled, elevated; suture deep; whorls in- 

 creasing very gradually in size, flattened on the sides, slightly 

 bevelled above and below the suture, and a little depressed in 

 the middle; under surface nearly flat, or a very little convex. 

 Surface marked sometimes by a few faint revolving lines. Aper- 

 ture subquadrate. 



Figure, natural size. 



Locality: From a white Miocene limestone in the extreme southern corner of 

 Ihe Maxima Martinez Kancho, Santa Clara County. 



This is the largest Turritella yet found in the State, and bears a close resemblance 

 to T. Saffordii, nob., of the Cretaceous. It differs mainly in the suture not being 

 so closely impressed as in that species.
