T. Whitneyi, n. s. 



PI. 28, Fig. 210, and 210 a. 



Shell fusiform, turreted; spire high, whorls seven or eight, 

 subangular ; suture small, hut distinct. Mouth wide above, nar- 

 rowed in advance ; canal slightly curved anteriorly. Surface 

 marked by prominent nodes on the angles of the whorls, pro- 

 longed slightly above and below; these are crossed by nume- 

 rous, well-marked, revolving lines, sometimes alternating in size. 



Figures, natural size, and magnified to show the peculiarities of the surface 

 markings. 

 Localities: Alizos Creek, near Fort Tejon, and a single cast from San Diego. 



BUCCINUM, Linn. 



B. LIRATUM, 11. S. 



I 

 PI. 28, Fig. 211. 



Shell ovoid, robust, test thick; spire low, whorls four and a 

 half to five, convex. Aperture elongate, deeply notched in ad- 

 vance ; outer lip simple ; inner lip lightly incrusted, more heavily 

 below than above ; umbilicus distinct, but imperforate. Surface 

 marked by numerous rounded, longitudinal ribs, with interme- 

 diate spaces somewhat smaller than the ribs themselves ; these 

 run somewhat obliquely, especially at the top, where they curve 

 slightly from behind forwards. The lower third to half of the 

 shell is marked by numerous small, revolving, impressed lines. 



Figure, natural size. 



Localities: Not rare at Martinez, Clayton, and Marsh's Kanch, in Contra Costa 

 County (Division B.). 



Except for the absence of the deep revolving groove on the middle of the body 

 whorl, this shell might be placed in the genus Pseudoliva.
