This very natural group is represented in the Tejon fauna 

 by Ficopsis remondii Gabb, F. hornii Gabb, F. cooperii Gabb 

 and F. coivlitcensis (Weaver). Conrad also included Ficus 

 mamillatus Gabb in this group as well, but it appears to belong 

 to the genus Ficus, as it lacks the relatively higher spire of 

 Ficopsis, its body-whorl is more globose and its outer lip has 

 no tendency to become angulated. 



Ficopsis remondii Gabb is sometimes almost without marked 

 angulation but in general, the specimen figured (See Plate 6, 

 figure 8) represents a typical form. This species lacks any 

 marked nodosity at the shoulder or upon the two carinae 

 below it. 



Ficopsis cozi'litsensis (Weaver) is an intermediate form, that 

 is, it bears certain resemblances to F. remondii on the one hand 

 and to F. hornii on the other. It differs from F. remondii in 

 that its shoulder is more definitely set off and in that the 

 carinae are more definite and are always nodose. Its nodes
