146 JOURNAL OF SCIENCE, 
Mr. Potts and Mr. Fereday each contribute a short entomo- 
Jogical paper to the volume. 
Mr. Maskell’s paper on the Coccidz describes a number of 
new species of this little-known group of insects, and proposes a 
new Classification of the section Lecanide. On the merits of the 
paper we cannot speak, as Mr. Maskell is probably the only per- 
son in New Zealand who knows anything about Coccide, but the 
work done testifies to the author’s care and observation. The 
paper is illustrated by two plates. 
Mr. H. B. Kirk’s paper on the Anatomy of one of the New 
Zealand Calamaries, Sepioteuthis bilineata, is worthy of notice as 
being the only anatomical paper in the volume. It is very gra- 
tifying to find one of our younger naturalists going below the 
surface in his investigations. The external characters of the sub- 
ject are first fully described, then the cartilages of the head, neck 
and fins ; a short account is given of the muscles; and finally 
the viscera, nervous system, and sense organs are described more » 
or less at length. The work appears to be well done as far as 
the rough anatomy is concerned, but it is to be regretted that the 
author did not goa little further in his examination of some of 
the parts. For instance, no attempt seems to have been made 
to inspect the vascular system, and in the description of the re- 
nal organs no mention is made of the true renal sacs, or of their 
openings into the mouth’s cavity, only the glandular outgrowths 
of the vena cava being noticed. The histological observations 
are undoubtedly the weakest part of the paper : it gives no infor- 
mation as to the minute structure of a sense organ to say that it 
“shows interlacing fibres under the microscope” ; or as to that 
of a gland, to describe it as composed of “loose fibrous tissue 
interspersed with yellow concretions.” The six plates illustrat- 
ing this paper are drawn with scrupulous care. 
Prof. Hutton contributes four papers on Mollusca. The first of 
these, on “Some New Zealand Land Shells,” deals chiefly with the 
dentition of a large number of species, and adds 26 new species. 
The plates illustrating this paper are, unfortunately, very rough in 
execution. There is also a feature in regard to them which is cer- 
tainly an inexcusableerrorofthelithographer’s. Inthe table giving 
the explanation of these plates the enlargement of the figures is 
given, but a comparison of plates X. and XI. shows that in re- 
ducing the original drawings by photography, no fixed standard 
has been adopted. The reduction is different in these two plates. 
The same blunder was made in some platesin Volume XV., and 
care should have been taken that it did not occur again. Fol- 
lowing this paper is a “ Revision of the Land Mollusca,” ona 
natural classification. The knowledge of the group is confessedly 
imperfect, but this paper, and the same author’s “ Revision of 
the recent Rhachiglossate Mollusca,” are extremely useful, as 
bringing together in a compendious form the descriptions and 
synonymy of all the known species. A large field of work still 
lies before conchologists in determining the affinities of our mol-
