35. Lindigia ? nodosum, sp. nov. 



Helicancylus ccquicoslatiis Gabb, Pal, Cal., Vol. II, p. 141, PI. XXV, figs. 

 20, a-g. 



Zittle refers this species doubtfully to the genus above 

 given, which he has placed as a subgenus under Turrilites. 

 Gabb figured the type of this species under the name Heli- 

 cancylus. His description needs no special revision, except 

 that the tuberculation is not sufficiently pronounced either 

 in his figures or his description. On the larger coils of the 

 spiral portion these tubercles are large and circular in 

 section, or slightly elongated, and abruptly truncated at 

 the top. 



Occurrence. — The type in the collection of the University 

 of California is labeled, " Cottonwood Creek, Shasta 

 County, California."

The largest specimen is a fragment about 11. 5 cm. in length, and in largest 

 diameter 1.5 cm. It is coarsely ribbed with strongly bent costa;, and shows 

 distinct lines of growth. The section is ovate but does not show the narrow 

 ridge along the siphonal edge as the figures of B. vagina appear to require. 

 There is a depression a little below the middle of the side which may repre- 

 sent it, however. There is a much closer resemblance found in the suture, 

 which is composed of broad, bifid saddles and narrow lobes, also somewhat 

 equally divided. The bifid or bipartite character is noticeable even in the 

 smaller divisions of both lobes and saddles. 



This species is only distantly related to B. chico'cnsis 

 Trask, but shows more affinity with the form described by
