Davidson, who examined them, wrote to me, 28th —These specimens are peculiar and puzzle me. They are notT. carnea, nor T. semiglobosa, and I am uncertain as to their properidentification. They approach most in shape to some specimens ofTer. semiglobosa, but I would not like to refer them to that almost look to me a new species. 1 1« 2 2a. Terebratula obesa, Sowerby, var. cuneata.
