^ Dr. Jeffreys also recognized Lacuna cra-ssior among Mr. Headley's specimens 
but, either purposely or inadvertently, did not incorporate the species with 
his list. Recent specimens have, however, confirmed the determination. 
2 liissoa costaia, Adams, and Hissoa seniisiriata, Mont., also occur in Mr. 
Headley's collection, but as the specimens were obtained from beds between 
tide- marks, and these small shells abound on the present beach, they must be 
considered as "doubtful" species, and I have omitted them from the list. 
J I have found this shell at Dlmlington only.
