the carina, a nodose spiral thread on the tabulation above the 

 shoulder and a nodose spiral line above the carina and close to 

 the wavy suture ; body-whorl marked by a strong carina at the 

 shoulder and by a nodose spiral line in its middle where a sec- 

 ond angulation occurs ; twelve to fifteen nodose spiral lines 

 occurring in addition to these two prominent lines described 

 above ; mouth oval ; outer lip simple. This species is easily 

 recognizable on account of its nodose spiral lines. 



Dimensions : — Length of broken type specimen, 22 mm. ; 

 width of body-whorl, 7 mm. 



Type: — No. 11057, University of California. Locality 458, 

 Tejon Quadrangle, Tejon group, west side of Grapevine Creek, 

 elevation 2050 feet, about 4>4 miles S. 6° W. of 1085 B. M. 

 about 400 feet (stratigraphic) above Basement Complex-Tejon 

 Contact. Coll., R. E. Dickerson. 



Named for its occurrence at the type locality of the Tejon 

 on the Caiiada de las Uvas.

 tology, vol. l,p. 101, 1864. 



This species was described as a Fasciolaria but careful ex- 

 amination fails to reveal any traces of plications and the posi- 

 tion of the sinus is that of the genus Surcula. 



This species belongs to the same general section of Surcula 

 as Surcula zvashingtoniana (Weaver), (See Plate 10, figures 

 7a, 7b), but details of sculpture readily separate them.

Plate 9, figure 8 

 The beautiful specimen figured is larger and more nearly 

 perfect than Weaver's type. It is very close to Fusus merriami 

 Dickerson (ms.) of Siphonalia sutterensis Zone of the Marys- 

 ville Buttes, but it differs somewhat in proportion and details 

 of sculpture.
