154 Transactions.—Zoology. 
The specimen figured came from Dunedin. It resembled the description 
and size of H. fatua, except that it was slightly spotted with rufous. It 
differed from H. zealandia, in being only sub-carinated. Its remarkable denti- 
tition and jaw of course take it out of Helix. Probably it must be formed into 
a new genus, but I have not the necessary books for determining this point. 
Limax acrestis, Linneus. I have no doubt now that my L. molestus is 
this species. The differences that I pointed out were the non-obliquity of 
the keel, which Mr. Binney says is quite inconstant, and the different shape 
of the ovo-testis. In this latter point I had not compared our slugs with 
European examples, but trusted to Mr. Newton’s figure in the Quar. Jour. 
Micros. Science, N.S., vol. 8, p. 26; as, however, I find that the teeth are 
quite identical, [drop myname. The radula has 98 transverse rows of teeth, 
each row having 42-142. On Pl. III, fig. u., I give figures of a central, 
lateral, and marginal tooth, from one of my type specimens from Dunedin. 
The jaw is figured at fig. p. 
Mrax antipopum, Pfeiffer. Jaw very slightly arcuate, with a slight 
median projection. (Pl. IIL, fig. a.) 
Radula -06 inch in diameter, and about two and two-third times as long, 
with about 92 transverse rows of teeth, which are slightly curved, the con- 
vexity being posterior. (Pl. IV., fig. s.) Teeth 40-1-40, of which 16 are 
laterals. The central tooth has a single cusp, the shoulders of which slope 
gradually into the base, and each carries a small cutting point. In the 
laterals the shoulders are more strongly marked, but the inner one gradually 
dies away and its cutting point gets very minute, until on the 18th or 14th 
tooth it cannot be seen, and the outer one is very small. In the 15th and 
16th teeth the median cutting point rapidly increases, and approaches 10 
size the aculeate marginal teeth. (Pl. IIL, fig. e.) : 
The specimen figured came from Dunedin, but I have also found it im 
the bush at Governor’s Bay, Banks Peninsula. 
Minax emarcinatus, Hutton. The jawis narrow, nearly straight, with a 
slight median projection. (PI. IIL, fig. s.) 
The radula is ‘07 inch in diameter, with about 90 transverse rows of 
teeth, which are slightly curved, the convexity being posterior. Teeth 
46-146, of which about 16 are laterals. These teeth differ from those of 
M. antipodum in having the cutting points much larger; the shoulders 2 
No. 1 lateral are much more sloping, and the shape of the reflexed part of 
No. 14 is quite different. (Pl. IIL., fig. 1.) I have figured the teeth of 4 
small specimen from Dunedin. : 
Anton Fuscus, Muller. My A. incommodus is, I think, identical with this 
species, of which I had seen no description until this year. I have only 
seen it from. Dunedin. The ribbed jaw is figured in PI. IIL, fig.
