Gray, and has been retained bj him in his " Guide," (1857), in 

 which he has referred it to the Cassidulid?e, giving, as characters, 

 " shell like Oassidulus,* [= Melongena,] but spire shorter; last 

 whorl very large ; mouth very open. Teeth ? Operculum very 

 small, ovate or claw-shaped." 



J^. canaliculata and F. carica being the only species enumer- 

 ated, the characters assigned to Fulgur might, with perfect pro- 

 priety, be transferred to " Cassidulus " melongena^ the type of 

 " Cassidulus," as distinguished from Fulgur! It might, there- 

 fore, be supposed that some transposition of diagnoses had been 

 made, but other species enumerated as Cassiduli forbid the sup- 

 position. However this may be, the diagnosis of Fulgur, cited, 

 is neither applicable to the species, nor is a distinctive generic 

 character introduced, and finally, Fulgur does not belong to the 

 family Cassidulidre even, but to the Buccinidie.f 



Under the name of Pyrula, all the living species of the genus 

 Fulgur and Sycotypus were enumerated by M. Petit de la Saus- 

 saye in a valuable memoir on the Lamarckian Pyrulge,J and the 

 limits of the group embracing those two genera were well appre- 

 ciated, although the distinguishing characters were not given. 

 The name Pyrula cannot, however, be retained for either genus, 

 as Lamarck mentioned, as the type of his genus in establishing 

 it, the P. Jiciis of Linnseus, and no other species ; and, in 

 accordance with the law of priority, the name is only applicable 

 to the group represented by that species, as has been perceived 

 by Gray, Woodward, &c. 



A list of the known species of the genus is now submitted.

* Cassidulus is an erroneous substitution for Cassidula, the name intro- 

 duced by Humphrey. 



t Dr. Gray, however, was excusable in referring Fulgur to the Cassidu- 

 lidse, as the characters of the animal were unknown till revealed by Dr. 

 Stirapson.
