tified by him, as well as Dr. Carpenter, as T. tuherosus, Phil. 

 In sculpture it agrees in some respects with confragosus. It 

 has, however, a double row of scales at margin of the whorls, 

 and Dr. Gould could scarcely have failed to notice its pitted 

 spire and color around columella, which is persistent on speci- 

 mens the most weathered. Its reference to tuherosus must have 

 arisen from an error in the Cumingian collection. That species, 

 as figured and described by Dr. Philippi, is granulose and tuber- 

 culose, of quite a different shape and belonging to another 

 genus. No species resembling it inhabits Polynesia. I should 

 look for it among species inhabiting the west coast of America. 

 The shell figured for it in " Conch. Icon.," from the Cumingian 

 collection, resembles the above species in having two rows of 

 scales, but on the figure they are distant from each other, and 

 in several other respects of sculpture, as well as color, it diifers 

 from the species described above, and quite distinct from tuhe- 

 rosus, Phil. The last whorl of the above species is about one- 

 half the length of the shell, and, with the penultimate whorl, 

 occupies three-fourths of the shell ; the whorls above are, conse- 

 quently, quite narrow and deeply pitted. 



From the undulating character of the suture, the rows of 

 scales on the penultimate whorl appear to be on opposite sides 

 of the suture, which, however, is not the case.
