Since publishing the original description and figure of this species, other and 

 better specimens have been obtained, and I am enabled to illustrate a more perfect 

 and older individual than in the first instance. A slight difference will be observed 

 in the line running posteriorly from the beak in the two figures, and the concentric 

 ribs also seem to vary in size. 



The present specimen, from my own cabinet, was obtained by Dr. Horn at Tejon.

This rather variable species is extremely common in the Martinez Group at 

 Martinez, and has been found in the Chico Group at Pence's Ranch, as well as in 

 the Tejon Group at Griswold's. I have now a single specimen from the latter 

 group from Martinez, associated with Turritella Uvasana, and other characteristic 

 Bpecies. The present figure illustrates a common, and one of the most marked 

 forms of the Martinez Group, Martinez, from the same bed with PugneUus hamulus. 



T. .EQUALIS, n. s. 

 PI. 29, Fig. 73. 



Shell moderate in size, nearly elliptical, thin, flattened; narrow 

 in its young state, proportionally broader as it grows older; beaks 

 very slightly in advance of the centre, small ; cardinal margins 

 slightly convex; base broadly and regularly curved; ends rounded, 

 the anterior a little the narrowest. Surface marked by lines of 

 growth, most prominent near the extremities. 



Figure, natural size. 



Rare in the Martinez Group at Martinez. 



From T. ooides it can be distinguished by its central beaks and nearly equal ends;
