twice as wide as one lateral area ; striae on sole as in A. 

 g agates. 



Described from two specimens, doubtless Gray's types, in 

 the British Museum. This species differs little from A. 

 gagates except in colour. 



Amalia antipodarum, var. nov. pallida. 



Length (in alcohol) 21| millim. ; sole pale ochrey, uni- 

 colorous, median area hardly twice as wide as either lateral 

 area; sole-strise as in A. gagates. Reticulation on body as in 

 A. gagates. Mantle dark greyish, with the edges pale and 

 the sulcus dark. Neck above dark grey. Body well keeled, 

 whitish, greyish on each side of keel. Respiratory orifice 

 rather posterior. Not a rugose slug. 



Described from a specimen from Wellington (Otago Uni- 

 versity Museum). 



Amalia antipodarum, var. emarginata (Hutton). 

 Milax emarginatus, Hutton, Man. N. Z. Moll. 1880, p. 26. 



Length (in alcohol) 27 millim. ; sole and sides whitish, 

 back dark greyish. Keel more or less pale. Median area of 

 sole narrower than both lateral areas together. Sulcus on 

 mantle not darker than the rest of the mantle. 



Described from a specimen found at Dunedin (Otago Uni- 

 versity Museum), in the British Museum. Closely allied to 

 var. pallida, from which it differs noticeably in its concolorous 

 mantle-sulcus. It does not appear to me that antipodarum, 

 pallida, and emarginata are more than three varieties of a 

 single species. 



h. Australia. 



Amalia maura (Quoy & Gaim.). 



Limax maurus, Quoy et Gaimard. {Hab. Port Jackson.) 



Limax olivaceus, Gould. {Hab. Paramatta.) 



Limax pectinatus, Selenka, Mai. Blatt. 1865, p. 105. {Hab. Sydney.) 



This Australian species is evidently very close to A. gagates, 

 but is probably a valid species. The supposed species A. 

 maura (Q. & G.), A. olivacea (Gld.), and A. jiectinata (Sel.) 

 are all from the same neighbourhood, and as the descriptions 

 agree in all important points, there need be no question about 

 uniting them. The oldest name, A. maura, has been quite 

 overlooked, the Limax maurus of Quoy and Gaimard 

 remaining unidentified by authors.
