A. papillatus, to compare its anatomy with all the details 
given by Dr. Simroth. 
According to Simroth’s able investigations (Nova Acta 
Bd. 54, Die Nacktschnecken Neu Seelands, p. 71, &e.), 
and his utterances when speaking on the systematic position 
of the Athoracophoride, it will be necessary to class A. papil- 
latus and A. marmoreus in different sub-genera. He says dis- 
tinctly that the most striking differences between the two 
species in form and cross-section of the animals and genital 
organs would almost justify the creation of two genera. 
The sub-genus Pseudaneitea has been proposed by T, D, A, 
Cockerell (P. Z.S., 1891, p. 217) for slugs of New Zealand 
and the Auckland Islands, resembling Athoracophorus, but 
showing a decided tendency towards the formation of a 
“mantle area” like that of Aneitea. The type and only 
species is A. papillatus, Hutton, sp. 1879 (=verrucosus, Von 
Martens, 1889). As sub-genus for A. marmoreus, Hutton, sp. 
1879 (=marmoratus, Von Martens, 1889), must of course be 
taken Konophora, the former generic name proposed by 
Professor Hutton in 1879 (Trans. N.Z. Inst., vol. xi., p. 332). 
Negjanella dubia, Cockerell (l.c.), is nothing else but 
A. bitentaculatus, Quoy and Gaimard. I could show Mr. 
Cockerell alcohol specimens of this slug which are lacking the 
‘‘mantle area’’ and dorsal groove, yet they were distinctly 
visible when the animals were alive; and also specimens of 
A. bitentaculatus, with the back pale-yellowish, marbled all 
over with black or dark-bluish grey. The specimen described 
by Cockerell is a very large one (length 53mm.), and I 
know of no other locality than the south side of Cook Strait 
where A. bitentaculatus attains such a large size. 
8. Bulimus antipodarum, Gray, 1848, 
Is said to have been found at Kaitaia by Dieffenbach, and 
recent collectors (Gillies and T. W. Kirk) are reported as 
having found this shell at different places in the northern part 
of the Province of Auckland. Opinions are divided as to the 
yalidity of the species; some consider it as the young of 
Placostylus bovinus, others take it as a good species. I 
therefore thought it well worth to investigate the question, 
and wish now to say a few words on the subject. Looking at 
the figure of B. aniipodarwm given by Smith (Voy. ‘« Hrebus 
and “Terror,” ii., Moll., pl.i., fig. 5), andreading Gray's descrip- 
tion (Dieffenbach’s New Zealand, ii., p. 247), one must come 
to the conclusion that this shell cannot belong to the genus 
Placostylus, the aperture being quite different, but it agrees in 
every respect with Cochlostyla. This opinion was evidently 
held also by the author of the species, for he says that it is 
allied to Bulimus fulgetrum, Broderip, from the Philippine
