DESCRIPTION OF A NEW SLUG. 



when fully exerted 20 mm., Mack, finely tuberculated, gradually 

 tapering from swollen contiguous bases. Mucus colourless. 



Charopa delta, Pfr. I found abundantly on the trunks of 

 trees in the scrubs of Mr. Bradbury's estate, Little Nerang Creek. 

 The animal is 13 mm., in length, colour wh'te, almost translucent, 

 posterior part of body sharply keeled terminating in a mucous 

 eland, a shallow furrow starts from the apex of the tail and runs 

 forward on each side to the lips, below this furrow the body is 

 smooth, above finely tuberculated. Tentacles moderately long, 

 cylindrical. The visual nerve shows as a black stripe arising 

 from the ganglionic collar and terminating at the eye. Habits 

 very active, emitting when crawling abundance of transparent 

 mucus. The epidermis is very deciduous readily scaling off in 

 large patches. In the same locality 1 also secured Diplomphalus 

 vinitincta, Cox % and a single dead specimen of Pedinogyra muhl- 

 eldtiana, Pfr. These two species are not among those enumerated 

 in the list which appeared in Part II of this volume. The keeled 

 periphery, dark colour, and thinner lip distinguish the latter from 

 Cunningham ; yet I doubt whether it is better entitled to specific 

 rank than other marked varieties of this variable shell. 



Only two immature living examples of Panda falconari 

 rewarded my exertions, though the scrubs were full of dead and 

 broken shells. They probably hide during the dry weather in the 

 nooks and crannies of the giant fig trees. The rubbish among 

 the buttressed roots of the great scrub trees is capital hunting 

 grounds for a naturalist, but too often he finds himself forestalled 

 by that enthusiastic conchologist and able collector, the scrub 

 turkey. In such a situation I captured a fine living Geotrochus 

 bidwilli, then finding a Rhytida (? confusa) I incautiously con- 

 fined the two together in the same box. Next morning I dis 

 covered that the Rhytida had stretched himself as far as he could 

 penetrate into the interior of UdwtllCs shell, and was in the act of 

 devouring the inhabitant. Drawing the shells apart the aggressor 

 was made to disgorge his breakfast in the shape of a long limp 

 string, . This interesting episode shows that the carnivorous 

 mollusca consume their vegetarian brethren ; also that, wanting a 

 jaw, they, having swallowed their food, possess no means of
