THE SLUGS OF NATAL. 161 



This has undoubtedly been introduced, and is fairly common 

 in Pietermaritzburg", and probably elsewhere. 



Genus Milax Gray. 



Milax gagates {Drap.). 



Limax gagates Dmparnaud, Tabl. Moll., 1801, p. 100, No. i; Hist. 



Moll. France, 1805, p. 122, pi. ix, fig. 1. 



As I have elsewhere pointed out (7, p. 230) the South 

 African examples of this species which have passed through 

 my hands have mostly differed slightly in anatomical details 

 from the European gagates, but these are not of sufficient 

 importance to warrant separation from that species. 



H ab. — Pietermaritzburg. 



Genus Agriolimax MorcJi. 



Agriolimax agrestis [Linn.). 

 Limax agrestis Linne, Syst. Nat., 1758, vol. i (ed. x), p. 652. 



All the examples I have seen of this slug are practically 

 identical with those found in Great Britain. 

 Hab. — Pietermaritzburg. 



Fam. UROCYCLID^ Simr. 



Genus Urocyclus Gray. 



Urocyclus kirkii Gray. 



Urocyclus kirkii Gray, Proc. ZooL Soc, 1864 p. 251; Gibbons, 



Quart. Journ. Conch., 1879, vol. ii, p. 139; 

 Heynemann, Jalirb. cl. Deutscb. Mai. 

 Ges., 1885, Bd. xii, p. 293; Cockerell, 

 Concbologist, 1893, vol. ii,p. 187; Siniroth, 

 Deutscb. Ost-Afr. IV, Nacktscbn., 1895, 

 p. 6. 



Amongst the many South African specimens belonging to 

 this genus which have passed through my hands I have met 

 with nothing that could be referred to this species.
