Thus Angas* thought he recognised the species from South 

 Australia, where it does not occur. Tate and Tenison-Woods 

 made a similar error in Victoria, the former attaching the name 

 to E.funerea Cox, the latter to E. albanensis Cox. 



Rehabilitation of this, the first described, must be the starting 

 point in the identification of the other Queensland members of 

 the genus. 



Accordingly, I forwarded examples of a shell collected in the 

 Gladstone district by Mr. Jackson, to the British Museum, and 

 requested Mr. E. A. Smith to compai'e it with Forbes' type. 

 With his usual kindness he did so, and replied 6/1/11 : — "We 

 have the types (two specimens) of H. iuloidea Forbes, received 

 from the Museum of Economic Zoology. In comparison, your 

 shells are extremely similar. I think, however, the thread-like 

 growth-lines in yours are rather closer together, or in other words 

 more numerous. Then the umbilicus is slightly more contracted 

 in yours, and the body- whorl consequently the least trifle higher. 

 Our two shells do not exhibit any red markings like yours. 

 Altogether, I am inclined to consider your specimens as a variety, 

 not having enough material to come to any definite conclusion as 

 to their being distinct." 



Figures and a description, more elaborate than those of Forbes, 

 are now presented, of the individuals examined by Mr. Smith, 

 and which I propose to call var. curtisiana. 



Shell thin, discoidal, broadly umbilicate, spire concave, but 

 barely so. Colour : protoconch slate-grey, remainder tawny olive 

 on which are disposed rusty flames, which are fairly regular, their 

 breadth apart, extending over two or three lamellae, but striking 

 backwards and forwards across their course and continuing upon 

 the base. Protoconch well defined, smooth, two-whorled, the 

 initial inclined. Including these, the whorls are four and a half, 

 rounded, parted by deeply impressed sutures, wound regularly, 

 last not descending. Sculpture : adult shell traversed from 

 suture to umbilicus by regular, delicate, erect lamellae, of which 

 the last whorl carries about one hundred; towards the aperture,
