In the second part of Morch’s “Review of the Vermetide,’ 1861, 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 varietal 
sense, in no respect according with the subgenus as described by the author. 
* T was perhaps wrong in referring the Mazatlan shells to Val.’s species ; but if Mr. 
Mérch is right in his own determination, the Mazatlan synonymy and locality must be 
expunged. There was no evidence of a typical Siphoniwm when the Reigen Catalogue was 
published, nor have I seen such from the whole coast, unless the minute operculum h, 
Brit. Mus. Col., tablet 2537, be supposed the young. Mérch 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. 
+ “Cpr.’s observations respecting Chenu’s plates (Maz. Cat. p. 306, lin. 18) are in part 
a 39 
erroneous, it being overlooked that Chenu has two plates marked ‘ V.’ ;” note *, p. 337,
