TASMANIAN LAND SHELLS. 47 



teeth on the lingual membrane is of the ordinary Bulimi type and 

 character. Mr. Legrand remarks — " This species has been found 

 fossilized in the tertiary formation of the North Coast." In this I feel 

 confident there is an error, for in the tertiary formation at Table Cape 

 only marine species of shells have hitherto been met with, nor is it likely 

 it will be met with in these beds. 



In this case, as in some others, I have not given a list of all the 

 works in which this and the other species are referred to, but I think 

 quite enough are mentioned for all practical purposes. 



The nearest Australian approach in form to this species is Bulirnus 

 indutus, and in colouration B. Angasianus, but both are, however, very 

 distinct ; in fact it is so totally different that no other form can possibly 

 be confounded with it.

Cox, Mon. 1868, p. 72, pi. xiii, fig. 1. 



Legrand'a Col. for Mon., sp. 2. 



Shell imperforate, conically-ovate, rather solid (sometimes very light 

 and thin), translucent, with little lustre, flatly and rather coarsely 

 longitudinally striated, whitish, originally covered with a reddish-brown 

 epidermis, often remaining as long close streaks along the lines of 

 growth, but frequently entirely absent, when the surface may have a 

 dull chalky appearance ; spire reddish, and papillary at the apex ; whorls 

 5, slightly convex, last nearly thrice the length of the spire, rounded at 

 the base ; aperture very slightly oblique, of a rather lengthened oval ; 

 pale yellow within ; peristome simple, straight, thin ; columellar margin 

 very slightly rolled back. 



Variety a. — Longitudinal markings black. 



Length 1-10, breadth 0*60 ; length of aperture 0*65, breadth 0-40. 



Habited. — Near the sea, clustering on small trees and shrubs. 



Found nearly all round the coast line, generally on sandy ground or 

 hillocks a little above high-water mark. It is almost invariably in 

 great profusion, gregarious, and clustering together, more especially on 

 the boobyallas and stunted wattles ; it has been got on the exposed 

 rocks near the sea on Bruni Island. Specimens kindly given me by my 

 friend Mr. B. Dyer, and said to have come from Spring Bay, on the East 

 Coast, are much darker than the ordinary form, the longitudinal 

 markings being of an intense black, and with a somewhat silky lustre. 



It is closely allied to B. Kingi from King George's Sound, and is, I 

 believe, of the same peculiar habit. It is the largest of our few arboreal 

 land mollusca. The fossil B. Gunni, from the travertin near Holart 

 Town, is very closely allied, and may, in fact, be the same species a little 

 modified by time.
