The spccifs upon which Moricand inflicted the more tlian sesqui- 

 ]ied:ili:in name of cinnamomeolineotus is usually somewhat smaller 

 than any of the preceding, and streaked rather than xlrifti-il with cin- 

 namon brown, or with the streaks obsolete. The peripheral keel, 

 while M> .-light as to hardly all'ect the rotundity of the last whorl, is 

 still quite perceptible. 



I coii>id'-r the locality, (Juiana. given by Troschel on the evidence 

 of specimens collected by Sckomburgk, as in all proliability erron- 

 eous. Troschel's investigation of the teeth was made on Sehom- 

 burgk's material, so that this citation also is open to doubt. See 

 Schomburgk's " Ueisen in Britiseh-Guiana," vol. iii. p. 540. Drouet 

 quotes the species, on the authority of Schomburgk, in his French 

 Guiana catalogue.
