187L] MR. J. BRAZIER ON AUSTRALIAN LAND-SHELLS. 321 



5. Descriptions of two new Species of Land-Shells from the 

 Bellengen River, New South Wales. By J. Brazier, 

 C.M.Z.S. 



1. Helix bellengenensis, sp. nov. 



Shell umbilicated, depresseclly orbicular, nearly discoid, rather thin, 

 radiately striated ; between the raised striae very finely punctured, 

 dark chestnut, and covered with a fine silky epidermis ; whorls 4|, 

 moderately convex, rather flattened at the suture, keeled at the 

 periphery ; base convex, rather finely striated ; aperture subqua- 

 drately ovate ; peristome white, in some specimens of a faint pink tinge, 

 moderately reflected ; margins approximating, the upper descending 

 in front ; columellar portion partly covering the deep umbilicus. 



Diameter — greatest 4| lin., least 4, alt. 2| lin. 



Hab. Manarm Creek, Bellengen River, {coll. Brazier) ; very rare. 



This fine rare species I found on standing dead trees {Eucalypti), 

 under the bark five feet from the ground. I also obtained a few 

 under logs on the ground ; it likes very wet places. 



2. BULIMUS LARREYI, Sp. nOV. 



Shell imperforate, ventricose, ovate, very thin, transparent, trans- 

 versely and finely marked with dark interrupted lines ; apex obtuse ; 

 whorls 4 to 4|, convex, last equalling more than one-half of the entire 

 length ; suture slightly grooved ; below the suture an interrupted yel- 

 lowish band tessellated with dark spots ; aperture oval, interior glossy ; 

 peristome simple, acute ; columella slightly recurved and reflected. 



Length I inch 2 lin., breadth 6 lin. ; aperture 65 lin., width 4 lin. 



Hab. Manarm Creek, Bellengen River, under burnt logs; very 

 rare {coll. Brazier). 



This interesting and new species of Bulimus differs from any of 

 our known species in being of so light and inflated a form, and in 

 the characteristic tessellated black spots at the suture. The first 

 specimen that I obtained of it was on my recent tour to the Bellen- 

 gen, called by some Bellenger and Billinger River, two hundred 

 miles to the north of Sydney : it was collected by my intelligent 

 aboriginal guide King Larrey. During my stay of two months 

 we only found four specimens ; since my return to Sydney I have 

 received two more from him. 



The animal is of an umber colour, full of wrinkles, with three 

 black stripes, one from each tentacle, and one down the centre of 

 the back, running longitudinally.
