 Plate 14, figure 5 



Shell fusiform with very low spire; six whorls; body whorl large 

 with long, slender, slightly curved canal; lip long, straight. Body

 portion of the body whorl above the shoulder slopes gently upward to 

 an impressed suture ; decoration, unknown. 



Dimensions. — Height, 20 mm. ; width of body whorl, 13 mm. ; length 

 of expanded lip, 8 mm.

ANCHURA GABBI, n. sp. 

 Plate 14, figure 4 



Shell small, fusiform, spire elevated, six rounded whorls, suture 

 deep. Surface of upper whorls strongly cancellated by transverse 

 ribs and faintly revolving lines ; body whorl strongly marked by 

 two carinae, the upper one of which extends outward to the tip of the 

 lip. Lip long straight perpendicular to whorls, tip acute ; canal 

 narrow, length unknown. 



Dimensions. — Width of body whorl, 6 mm., including lip, 11.5 mm. ; 

 length of whorls, 13 mm. 



Occurrence. — Martinez Group, one mile south of Stewartville ; 

 University of California Locality 1540. 



The specimen figured occurs in hard, gray-green, glauconitic sand- 

 stone typical of the Martinez Group. It is associated with Tellina 

 undulifera, Cucullaea matheivsonii, Tapes(f) quadrata, Turritella 

 infragranulata, Perissolax tricarnatus, and Trochocyathus zitteli, 

 characteristic Martinez species. 



It differs from A. transversa Gabb in having a shorter uncurved 

 lip and its body whorl is marked by two carinae instead of the one as 

 in A. transversa.
