Sub gen. 3. PSEUDANEITEA, Cockerell, 1891. 



Pseudaneiiea, Cockerell, P.Z.S., 1891, 217. Type : Athoracophorus papillatus, 



Hutton. 



Slugs of New Zealand and its subantarctir islands, resembling 

 Athoracophorus, s. str., but showing a decided tendency towards the 

 formation of a mantle-area like that of .\ncitea. 



These slugs are not always small. Notum usually finely granulate 

 with larger raised tubercles or papilla? between the lateral grooves. 

 Mantle-area distinct, triangular or rarely quadrangular, enclosing the 

 respiratory and renal orifices. Anus near the perinotum.

Animal (in alcohol) large, broadly elongate, with large dorsal 

 papillae, median groove extending over the head, side, grooves bi- and 

 tri-furcate, hyponotum very distinct. Colour yellowish-grey along the 

 sides of the back, the central part blackish, but the large papillae 

 whitish ; sole yellowish-grey. Body narrowing gradually towards the 

 tail. Notum flatly rounded, with very conspicuous median and lateral 

 grooves, the whole surface minutely granulate ; between the lateral 

 grooves 1 or 2 large raised round tubercles, forming a single row on 

 each side from the mantle-area to the head, double from the mantle- 

 area to within a short distance of the tail. Head-shield triangular. 

 reaching behind to the middle of the distance between the head and
