latter author states that his shell, so figured, and called by him 

 Bulimus teres^ was collected in Crete. It is described by Pfr. 

 as O. teres (Bulimus) Oliv. in Mon. Hel. Viv. II. p. 414. No. 45. 



We have not traced the B. perversus var. t. Gmel,, but the 

 R perversus Brug. is stated by Pfr. (in Mon. Hel. Viv. II. p. 536 

 with a ?,) to be a Syn. of C. rugosa Drap., from Spain. 



(2.) It is impossible to identify the figure given by Bowdich, 

 but it is referred to in Fer. and Desh. Hist., the latest published 

 synonymy of C. tridens. 



(3.) Sowerby, at the foot of his plate, has Olivier as the 

 authority for the specific name labiata, copied probably from 

 Maton and Eacket, without examination of Olivier's work. In 

 the text, Sowerby gives as Syn. T. labiatus Mont, "from 

 Malta." 



(4.) Eeeve also has the name laUata on the authority of 

 Olivier, copied apparently from Sowerby, to whose work he 

 refers. As Syn. he also has T. labiatus Mont. 



(o.) Miss Catlow, under C. costulata Lam. refers to Sowb. Gen. 

 f. 3, {C. labiata, Oliv.) and adds as Syn., Helix bicanaliculata, 

 Fer. and Turbo bidens Chem., which latter is, according to Pfr. 

 in Mon. Hel. Viv. II. p. 397. No. 4., Syn. of C. laminata (Turbo) 

 Mont., from Europe. Under C. labiata Oliv. (Conch. Nom. p. 

 147, No. 83.) the authoress has the same reference to Sowb. Gen., 

 adding as Syn. Helix labiatus Mont. 



(6.) Pfeiffer in his synonymy of C. tridens refers to Dillwyn, 

 without any qualification, thereby, in a measure, adopting the 

 whole of his errors ; and this is the more extraordinary, inas- 

 much as Pfeiffer has precisely the same unqualified reference to 

 Dillwyn, as part of the synonymy of C. labiata.
