At my request Mr. E. A. Smith examined the type of G. sul- 

 cosa in the British Museum, and replied that it proves to be a 

 variety of G. ardens von Salis, and the Australian habitat a 

 blunder. G. ardens is a common and variable Mediterranean 

 shell. Bucquoy, Dautzenberg, and Dollfus have reviewed it 

 exhaustively in the " Mollusques Marins du Roussillon" (Fasc. ix. 

 1885, p.379), but the synonyms of Adams escaped their attention. 



Gibbula venusta A. Adams. 



A. Adams, Proc. Zool. Soc. 1851 (1853), p.187. 



This was ascribed by its author to Australia, but Mr. Smith 

 relegates it also to a variety of G. ardens von Salis. In this case 

 bad work bred no further evil. 



Clanculus albinus A. Adams.

 Manual Conch, xi. 1889, p. 1 60.

The " accessible information " on this species is valued by the 

 latest monographer as " mere trash." Brazier has recorded that, 

 in December, 1871, he found one specimen of this rare shell, with 

 the apex broken, on the beach of Fitzroy Island, North Queens- 

 land.* This citation renders G. albinus an object of interest to 

 Australian conchologists, and to facilitate its recognition a figure 

 and description of a cotype from the British Museum are here 

 given. Within the genus Clanculus the species should be inter- 

 calated near C. clanguloides Wood. 



Shell large, very solid, deeply and rather widely false-umbili- 

 cate, globose-conic. Spire obtuse. Whorls about six in number, 

 wound obliquely, slightly gradate, rounded at the periphery, a 

 little descending and constricted at the aperture. Base rather 

 flat, extending obliquely. Colour pale buff, punctate with small 

 irregularly scattered crimson or brown dots. Sculpture : small
