Aleutian Islands; the fignred type from Kyska Harbor, Kyska 
Island, Dall. U.S.N.M., 108976. 
The shell is of a cream color with pale brown flammulation which is 
apt to fade in cabinet specimens and is not reJ5resented on the figure 
of the type, but when the shells are fresh is of a lively color. B. fin- 
maThiantim, Verkruzen, from the northern coast of Norway, is similarly 
painted but differently sculptured.

the last three were practically synonyms of each other. Humphrey's 
anonymous catalogue, without diagnoses or references to literature 
except the almost equally barren Portland catalogue, I have always 
rejected as not properly entering into scientific synonymy, although
