vii., of the Hist. Anhn. s. vert., has neither title-page nor date, but 

 the citation in the index of Parts One and Two is evidence of 

 separate publication, and hence of definite priority of name for the 

 recent Tasmanian shell. In that case Deshayes was not entitled to 

 alter the name. 



He, however, took the view that as the name was twice used by 

 Lamarck one should be changed, and he renamed the Tasmanian 

 shell Calyptraea lamarckii* Shortly afterwards the same species 

 from Western Port, 14 fathoms off Cape Dromedary and Jervis 

 Bay was described as Crepidula tomentosa Quoy k Gaim.f 



Tryonj considered that C. comma-notata Sowerby,§ was a 

 sjmonym, but as that was described from the Guinea coast, the 

 reference is improbable. But Gray transferred the name comma- 

 notata to a shell from New Zealand. ||

In the British Museum a series from St. Vincent's Gulf, pre- 

 sented by Dr. J. C. Verco are thus identified. From these and from 

 Gray's types it appears that the species determined as Galerus pel- 

 lucidus by Angas from Port Jackson, by Tate from St. Vincent 

 and Spencer's Gulfs, and by Tate and May from Frederick Henry 

 Bay, Tasmania, is properly C. tenuis. Hutton has statedll that 

 Sigapatella scutum Lesson is synonymous with C. tenuis. Under 

 Lesson's name the present species is reported from Victoria by 

 Gatliff and Gabriel. The identity of Lesson's unfigured species is
