VOL. 57. 



This is of much the same type as L. hlanfordi but larger, more 

 inflated and with an anterior projection of the margin instead of 

 the straight truncation visible in those varieties of hlanfordi which 

 have not a medial sulcus. There is an extremely faint indication 

 of a convex undulation at the front edge of the pedicel valve. 



The interior of the pedicel valve is much like that of L. hlanfordi 

 with three conspicuous genital sinuses on each side, rather broad 

 and bifurcating near the margin. The brachial valve has an even 

 shorter septum than hlanfordi, witli two straight unbranched 

 sinuses medially and one on each side with about four lateral 

 branches which bifurcate near the margin. There is a hardly dis- 

 tinguishable cardinal process. The deltidia are coalescent medially, 

 and more or less wrinkled.
