been made of their animals, and I am therefore disposed to 

 leave them much in the same series as they stand in my 

 treatise on Malacology, pp. 208 and 344. 



The shells I am now about to describe belong to the 

 singular group of amphibious Testacea above noticed. They 

 are all of a small size, and the inner lip, as in Melampus, 

 is strongly toothed or plaited, but, unlike the shells of that 

 division, the inner lip is not striated ; and the spire, instead 

 of being very short and obtuse, is produced and pointed, so 

 as much to resemble the form of a Bulimics. Thus dis- 

 tinguished, I think it better to place them in a group by 

 themselves, rather than under Melampiis. All three are in 

 Dr. Milligan's Museum ; the two first were found by him in 

 Oyster Cove in abundance, often above high watermark; 

 but the third, solida, which has every appearance of being 

 a marine shell, was found cast up by the water on the south- 

 west shores of Flinder's Island, along with a small species 

 of Paludina, found in brackish pools and marshes, both in 

 Australia and Tasmania. 



Judging from the shells alone this little group appears to 

 be the intermediate between Melamjjus and Pedipes. 



Oremnobates. 



Animal, amphibious. Shell, small, oval. Spire, rather 

 pointed, as long as the aperture. Aperture, not contracted, 

 Pillar, with strong plaits. Inner lip, thin, smooth inside. 



Sp. \. C. cornea. Plate VIL, fig. 1. 



Shell ovate, thin, light, covered with an epidermis ; spire 

 rather thickened, but not longer than the aperture ; pillar 

 with two plaits — the first large and central, the second small 

 and basal. Inhabits Oyster Cove, near Hobart Town. 



The general colour is olive brown, sometimes more or less
