This shell bears great resemblance to the Bid. ovatus. The bodj^- 

 whorl has three brovv'nish bands, and the others have two, one in the 

 middle and the second on the suture ; this last band is interrapted 

 by the epidermis, so that it seems as if this band was sprinkled with 

 red and yellow spots. The base of the last whorl is of a green colour 

 where the columella is reflected.

This shell is like Bul. guimaracensis, but more slender, and the 

 proportions of the volutions differ.

Though this BuUmus on the first sight bears great resemblance to 

 the Bul. bullula, it is still very distinct. 



Mr. Fraser then characterized two new species of Birds from West-
