REVIEW OF THE GENUS PYRULA (LAMARCK), 

 AND DESCRIPTION OF A NEW SPECIES. 



By G. B. SOWERBY, F.L.S., F.Z.S., 

 London. 



Owing to Lamarck's having grouped together as Pyrula (Pear Shells) 

 species not only of different genera, but belonging to totally distinct 

 families, it has been regarded as a matter of some uncertainty to which 

 group that title should apply, most modern authors adopting it for 

 a group of Fusidce (Ha/iifusus and Melongena) . Lamarck's type of 

 the genus Pyrula, however, is the Bulla fiats of Linne, so that 

 Woodward* rightly gives Pyrula fiats as the type, but wrongly gives 

 Myristica (type melongend) as a sub-genus of the same. As is clearly 

 shown by Dr. Fischer, the true genus Pyrula consists of the very 

 well-defined group of Mollusca that has been variously called Fiats, 

 Ptatla, and Sycotypus. Fischer has, however, taken upon himself 

 to amend the spelling of the name, rendering it Ptrula, which seems 

 to me a very unnecessary alteration.
