Murex florifer. Plate 9. Fig. 42. — A new species, recently collected on 

 the shores of Honduras by Mr. Dyson, in which the varices present a 

 characteristic row of leaf -like fronds. — From Mr. Cuming's collection. 



Genus 4. TYPHIS, Be Montford. 



Animal ; unknown. 



Shell; small, Murex-shaped, mostly trivaricose, with a hollow 

 spouted tube protruding from the upper part of the whorl, in 

 the centre of the area between the varices; spire rather 

 short, sometimes elongated ; columella smooth, aperture small, 

 rounded. Operculum horny. 



When treating of tins singular group in the ' Conchologia Systematica ' 

 I inclined to believe with M. Deshayes that it was sufficient to regard it as 

 a sectional division of the preceding genus ; I now, however, appreciate 

 the character by which the Typhides are distinguished, as one peculiarly 

 generic, inasmuch as it is not the modification of a spine, nor has it an 

 analogous representative in any other genus. 



The shell of Typhis is similar in form and general aspect to that of 

 Mtirex, but uniformly small ; its peculiarity consists in having a more or 

 less elongated spouted tube, in the centre of the area between the varices, in
