wiih very faint transverse striation on the later ones, show- 

 injij crennlation, nnder a lens, in the shallow sutnres ; the 

 last whorl less rounded than its predecessor, and almost Hat, 

 receding somewhat towards the aperture in front. Aperture 

 quadrate, rounded at the base ; outer lip slightly receding; 

 peristome white and shining, narrowly retlexcd, eoluniellar 

 margin more so ; rima very small ; dentition none. 



Lung. G-2 ; lat. 5-8 ; apert., alt. 2'2, lat. 2-0 ; last whorl 

 4'5 mm. 



Type-locality. jMtisberra River Valley [B. Cressy). 



Gonaxis {East rep taxis) venyoensis, sp. n. 



Shell comparatively large, oval, rimate, thin, transparent, 

 olivaceous, sn.ootli and glossy in front, less so on back. 

 Spire produced, left side very convex, right nearly straight ; 

 apex roundly conoid. Whorls 6^, rather flat, rapidly in- 

 creasing, the li apical microscopically malleate and faintly 

 spirally striate ; the next four covered with close, prominent, 

 oblique, transverse striae, with spiral pitting in the inter- 

 stices ; except immediately below the suture on the back of 

 the shell, the sculpture becomes very faint on the last whorl, 

 which is almost smooth, especially in front; suture simple, 

 shallow. Aperture quadrate, rounded at base ; peristome 

 white, shining, slightly thickened ; columella straight, margin 

 moderately reHexed over the rima; callus and dentition none. 



Long. 25*2 ; lat. 1-1-6; apert.,alt. 8*8, lat. 8'6 ; last whorl 

 19'5 mm. 



Type-locality. District 15 miles north of Macequece (B. 

 Cressy). 



Gulella enneadon, sp. n. 



Shell rather small, tun-shaped, broadly rimate, thin, 

 transparent, faintly olivaceous vitreous. Spire produced, 

 sides nearly parallel, slightly convex; apex bluntly lounded. 

 Whorls 7^, nearly flat, gradually increasing, the 2 apical 

 smooth, remainder covered with close fine stria3, which are 

 only just visible without a lens ; suture shallow. Aperture 

 nearly square, only slightly rounded at base, showing the 

 following nine-fold dental process : — a small sharp denticle 

 in the centre of the paries ; a large curved parietal plait ou 

 its right ; a large bifid tooth halfway down the outer lip ; 

 two minute denticles between the last-mentioned and the 

 base ; a small sharp basal tooth; and a two-cusped fold iu 

 the angle of the columella and paries; peristome shining, 

 white, reflexed ; rima circular.
