 proposed after the genus " Pyrula " was definitely limited.

What is the Pyrula reticulata of Lamarck ? That author, 

 Deshayes and Kiener consider it distinct from the P. ficoides. On 

 the contrary, Reeve, Kobelt, Tryon, and G. B. Sowerby (1892) have 

 united them or considered them as varieties of one and the same 

 species. 



After a careful consideration of the original diagnosis, and the 

 description given by Deshayes and Kiener from Lamarck's type, also 

 the figures in the Encyclopedic Methodique and in Kiener's work> 

 I am of opinion that not only is P. reticulata distinct from P. ficoides, 

 but that it is the same form as that previously named P. papy7-atia by 

 Say, and afterwards P. gracilis by Philippi. 



The size, four inches, considerably exceeds that of average speci- 

 mens of P. ficoides, although that species at times does attain that 

 length, and the colouration is quite different. P. reticulata is a pale 

 whitish shell, with very feeble light-brown spotting upon the principal 

 transverse ridges, and the aperture is brownish far within, becoming 

 whitish towards the outer lip. On the contrary, P. ficoides is a 

 species exhibiting a considerable amount of variegation in colour.
