 In the second part of Morch's " Review of the Vermetidce,'" 18G1, pp. 

 326-365, occur the following. A portion of the genus Bivonia is united to 

 Spiroglyphus. Petaloconchus , Aletes, and part of Bivonia are united to Ver- 

 metus, Morch (non auct.). The name Aletes appears to be used in a vai-ietal 

 sense, in no respect according with the subgenus as described by the author. 



* I was perhaps wrong hi referring the Mazatlan shells to Val.'s species ; but if Mr. 

 Morch is right in his own determination, the Mazatlan synonymy and locality must be 

 expunged. There was no evidence of a typical Siphonium when tbe Reigen Catalogue was 

 published, nor have I seen such from the whole coast, unless ih • minute opertni I urn h, 

 Brit. Mus. Col., tablet 2537, be supposed the yqung. Morch says, " the lid is unknown." 

 The operculum of the similar Mazatlan species, on which the subgenus Aletes was 

 founded, is described in Maz. Cat. p. 302. 



t " Cpr.'s observations respecting Chenu's plates (Maz. Cat. p. 306, lin. 18) are in part 

 eiToneous, it being overlooked that Chenu has two plates marked ' V.' :" note *, p. Lij,.
