LIMA.

Affinities. In the character of its ornamentation this form resembles Lima sub- 

 xquilateralis, d'Orbigny (see p. 49), from the Cenomanian of LeMans, but the shell 

 is not so high, is less pointed in the umbonal region, and has a longer hinge-line. 



In outline this form resembles the example figured by Ravn J as Lima Forch- 

 hammeri, von Hagenow, but possesses a much larger number of ribs. 



Remarks. I have seen one specimen only, which is in Dr. Blackmore's 

 collection.

Affinities. This form is closely related to Lima granulata (see below). The 

 ornamentation appears to have been similar in both cases, but in L. composita the 

 scale-like spines on the ribs are much less perfectly preserved and usually appear 

 as tubercles only. In L. composita the shell appears to be rather less oblique and
