Ac., in New Zealand alone, which serves to give a very fair idea of 
the extreme richness of our fauna in this group. The list is as 
follows : — 
Larfochilus, 8 species ; Realm, 4 species; Ilydrocena, 1. species; 
Athoracophorus , 4 species; Flammulina , 13 species; Oeronha , 2 
species ; Phacussa , 3 species ; Thera sia, 7 species ; JPyrrha , 2 species ; 
Phenacohel Lv. 3 species; Allodiscus, 12 species ; Suteria , 1 species; 
Thalassohelix , 5 species ; Fndodonta , 11 species ; Char op a, 22 species ; 
JPlienacharopa, 1 species; Aeschrodomns , 2 species; Laoma , 4 species; 
Rhrixynathiu ?, 21 species; Otoconcha, 1 species; Ariophanta , 1 species ; 
Rhytida , 0 species; Raryphanla , 5 species; Schizoy fossa, 1 species ; 
Rhenea , 2 species. 
Thus we see that in New Zealand alone there are no less than 
142 species of cryptozoie moilusea, and the strangest part of it is that, 
according to Hedley and Suter,* “ the 'whole of the species are now 
known to be strictly endemic.” Surely there must be something 
about the moilusea which is especially favourable to geographical 
variation ! 
The comparative richness oE this group in known species may, 
however, be partly accounted for by the large amount oE attention 
which has been devoted to it, especially of late years. It would 
be impossible to attempt to give an adequate idea of this work on the 
present occasion, and I cannot do better than refer the uninitiated to 
the valuable list of literature given by Messrs. Hedley and Sutcr* in 
their “ Reference List of the Land and Freshwater Moilusea of New 
Zealand,” which includes the more important publications on the 
Land and Freshwater Moilusea of all the Australasian colonies. 
Where there is so much to choose from it would be difficult, espe- 
cially for a non -specialist, to select those forms of Australasian Land 
Moilusea which are most deserving of mention ; but there appears to 
be a general consensus of opinion that, for interest; and peculiarity, 
the bitentaculate slugs of the family Lmellidie take the palm. These 
remarkable slugs are of large size, and form a conspicuous feature in 
the cryptozoie fauna, especially of New Zealand. TYeir most obvious 
characteristic is the absence of the smaller pair of tentacles met with 
in other slugs, only the larger eye-bearing pair being present. Two 
genera are recognised, viz. : — Athoracophorus ( Janella ), of New Zea- 
land and the Admiralty Islands ; and Aneitea ( Tribomophorus ), of 
Australia, the New Hebrides, and New Caledonia. 
The common New Zealand Athoracophorus is a large and hand- 
some slug, which I have often taken under dead wood. The animal is 
of a greyish colour, and the dorsal surface is shaped and veined much 
like a leaf, and sometimes beset with large, conical, retractile papilla?. 
The Australian Aneitea ( A . GrtieJJli) is found in ISew South Wales 
and Queensland, and according to Hedley may attain a length of about 
inches! This is also a very handsome animal, with its yellow 
ground colour ornamented with bands of red. An interesting account 
of it is given by Mr. Hedley in his paper “on Aneitea GvacJJii and its 
allies, ”f where a valuable summary of our knowledge of the Janellidae 
will be found.
