frequently adopts the same name for a distinct species, which 

 Mr. Reeve confounds with concinna, Dill. The name of the 

 author, Deshayesii being occupied, we have attached to it the 

 name of divisa as below. 



We also exclude modesta, Desh., for reason of being trans- 

 versely striate. T. Matheroniana, Desh., was originally included 

 by Mr. Reeve in the synonymy of both aciculina and stri- 

 gillata. In his errata he confines it to the former, which is 

 probably a mistake, as it should be undoubtedly classed with the 

 latter, as we place it above. 



Of all the varieties of this species, Verrauxii departs most 

 widely from the type in color, but especially in sculpture. 



Its ribs are regular and closely contiguous. The variation in 

 the others consists mostly in color, and the ribs being more or 

 less developed. From aciculina it may be distinguished by the 

 aperture being more narrow, not effuse at base, and in being 

 spotted beneath the suture. Barilla, Desh., is the connecting 

 link between the two species.

The species named aciculina by Lamarck, from Senegal, we 

 hold to be T. cinerea, Born., as classed by Mr. Hinds, and the 

 above allied form, inhabiting Polynesia and the East Indies, to 

 be distinct. M. Deshayes ignores the Lamarckian species en- 

 tirely, for reason of the error made by M. Kiener in illustrating 

 it. Figure 13a, on plate 7 of Kiener's monograph, is most 

 assuredly widely distinct from any variety of cinerea ; those of 

 13 and 13b may possibly represent varieties. 



Mr. Reeve figures the Polynesian form correctly, but names it 

 aciculina, and represents the Atlantic species correctly under 

 name of cinerea, Born., but, in his list of localities, allows it a 

 cosmopolite range. 



The above differs chiefly from cinerea, Born., in the shape of 

 its aperture, which is widely effuse at base, and truncate. On 

 the majority of mature specimens there is a sinus at upper part
