one) was placed in its cage, it seized it across the body as a Jack 

 would a Roach, pressing its fangs deeper and deeper into the animal, 

 and never relaxing its hold, even when the rat died. It then, with 

 extreme caution, without withdrawing its hold, worked the head 

 towards its mouth, and gradually swallowed the prey in short 

 "gulps" or bolts. Five or six persons watched the process in per- 

 fect silence, which did not appear to incommode or annoy the snake. 



4. Descriptions of eight new Australian Land-Shells. 

 By John Brazier, C.MZ.S. 



[Received October 11, 1871]. 



1 . Helix (Hadra) darwini. 



Shell umbilicated, depressedly globose, very thin, finely granulated 

 and radiately striated ; spire moderately elevated, obtuse ; whorls 5, 

 slowly increasing, convex, last roundly convex, slightly descending 

 in front, dirty yellow; base convex, sculptured the same as the upper 

 surface; umbilicus rather small, deep; aperture diagonal, ovately 

 lunate ; peristome very little reflected, white ; margins approximating 

 and joined by a thin callus, columellar margin reflected and half co- 

 vering the umbilicus.

Hub. North coast ot Australia {coll. Brazier). 



I received two specimens of this species from a friend who col- 

 lected them in the far north of Australia ; but the precise locality 

 was not sent with them. It is allied to Helix forsteriana, Pfr., 

 from North-east Australia. 



2. Helix (Hadra) stephensoniana. 



Shell umbilicated, turbinately globose, somewhat pellucid, of a fine 

 straw-colour, faintly and obliquely £ f rkted, rather puckered at the 

 suture ; spire subconoid ; whorls 5^, moderately convex, last convex 

 and inflated, deflected in front ; base convex ; aperture oblique, lu- 

 nately circular ; peristome light pink, straight ; margins approxi- 

 mating, upper margin rather thickened and expanded, columellar 

 margin arcuate and reflexed, covering half the umbilicus, which is 

 deep and moderately large.

Hub. Port Denison, Queensland, North-east coast of Australia 

 (coll. Brazier). Rare. 



This species is of a fine straw-yellow colour on the last whorl, 

 the other whorls being nearly white ; the lip is of a light pink 

 colour. I only know of one specimen, which is in my own cabinet. 



3. Helix (Hadra) bennetti. 



Shell umbilicated, depressedly globose, very thin, finely rugosely 

 striated and minutely granulated, dark-yellowish horny ; spire rather
