48 MOILr.>-CA OF KI.NfJ ISLAND, 



and a few Chitons, with a jrotidly number of minute forms, 

 found in shell sand, such as KP"Pi'ally live under and amongst 

 stones and rocks. A much more sheltered spot is Fraser on 

 Sea Elephant Bay. Middle East Coast, and here washed up 

 on the beach were most of the larger species taken. A longer 

 residence at this spot would doubtless add considerably to 

 the list. Two species of land shells were taken, and the 

 larger one, (Itlnritii^ victnriir, is very interesting, as its ap- 

 pearance stems to suggest the necessity of land communi- 

 cation with Victoria at some period, as this species occurs in 

 that State, but not in Tasmania. The great majority of the 

 marine species are also common to Tasmania, although a few 

 Victorian species appear which have not yet crossed to Tas- 

 mania. An extremely small pei-centage appear peculiar to 

 the Island; one of them is Ca»th(tn(s khiti'icoUt, Tate and 

 May, and there are four minute species which appear to be 

 new to science, and which 1 take this opportunity to describe. 

 In the following list there are seme species not taken by 

 myself; those of them which appear in the "Wombat" list 

 are marked by an '■*, and tho.se from Tenison-Woods' de- 

 scriptions and Census by a t- Altogether I here catalogue 

 227 species. 



Philobrya subpurpHnu, Sp. nov. 



Shell minute, ovately pyriform, hinge line .straightish. 

 Proto-conch small and inconspicuous, consisting of a minute 

 boss on a small flattened area. Colour yellowish, purjilish 

 brown at the umbos, extending downwards over part of the 

 .shell. Dead shells are white, with a purple stain branching 

 from the um))o on each side of the centre of the valve. The 

 exterior is smooth except for rather prominent grjwth lines. 

 The hinge consists of a .series of vertical ridges and grooves 

 on a flattened plate, and below this are about six ridges or 

 lira? which slightly crenulate the margin on what I take to be 

 the posterior side. 



Dimensions of Type. — Height, 2; breadth, 1.7 mill., but 

 some specimens are rather larger. PI. VII., fig. 1. 



Type from Eraser, King Island, taken by Mr Hasset- 

 Hull. I also collected numerous single valves in shell sand 

 at Currie Harbour. 



Ml/IHtd jiolHd, .Sp. nov. 



Shell minute, smooth, glossy, shining, and semi-trans- 

 parent, very ine(|uilateral. much produced on the anterior 

 side, umbos small. Internally there is a strong flattened
