ON THE SYNONYMY OF HELIX (HADEAJ GULOSA, 



GOULD. 



By John Brazier, C.M.Z.S., F.L.S. 



The subject of this present contribution, Helix (Hadra) gidosa, 

 Gould, was first obtained by me at Port Hacking and other places 

 included in, and now known as, the National Park in 1859-1860; 

 also between Cook's and George's Rivers, at places now called 

 Kogarah, Rockdale, and Hurstville, then known as Gannon's 

 Forest, and at Bulli Pass in 1864, 1865, 1866. Specimens were 

 named and submitted in 1868 to Messrs. George French Angas 

 and Henry Adams for identification, and were duly returned as 

 identical with H. gulosa as defined by Gould in 1846. Gould's 

 specimens were first obtained by Mr. J. Drayton, of the United 

 States Exploring Expedition, in the Illawarra district in the year 

 1839, and were re-described by Pfeiffer in 1847 as H. coriaria from 

 specimens reputed to have come from Ceylon. The shell was next 

 characterised by Morelet in 1853, under the title H. morosa, as 

 coming from Moreton Bay ; and in 1859 Pfeiffer, under the name 

 of H. coriaria, originally described from Ceylon by himself, in 

 1847, recorded this species as occurring in Western Australia. 

 Gould, in the Otia Conchologica in 1862, p. 243, suggests a new 

 generic name, Badlstes, for his H. gulosa. In the same year this 

 author also published an account of the occurrence of the species in 

 Australia. In 1864 Dr. Cox re-described H. gulosa under two 

 distinct specific designations, viz., II. Master si and 77. Scotti, the 

 former regarded by him as an intermediate form between H. 

 Grayi, Pfr., and H. Jervisensis, Quoy and Gaimard. 



Four years subsequently, 1868, Pfeiffer sinks H. gulosa as 

 merely a synonym of H. Lessoni, disregarding Cox's supposed 

 species.
