GENERAL NOTES. 179 
up to date. It is a pity however that the formule of the 
minerals given are not written like any other chemical formula, 
for while 2 Fe,O, + 3 H,0O is readily understood by every tyro 
in chemical symbolism—z2 Fe + 3 H is not. Besides, if the dot 
stands for oxygen, then 4 is certainly an incorrect formula for 
water. However, this is a trifling fault in an otherwise excellent 
paper. 
About a fifth of the whole volume is occupied with papers 
on the Maori race, many of them of great value. Some of these 
would have been none the worse of condensation, and the 
volume as a whole would thus have been improved. 
We think that a very valuable addition might be made to 
the annual volume in the form of an Appendix, mentioning all 
scientific papers dealing with New Zealand matters which have 
appeared in foreign journals during the year. Such a list would 
be very useful for reference. 
In conclusion, we would congratulate Dr. Hector and his staff 
on the general excellence of the work which they have published.

FRAGMENTA PHYTOGRAPHIZ AUSTRALIA. — The ith 
volume of this valuable publication has been forwarded to us by 
the learned author, Baron F. von. Mueller. In addition to fasci- 
culi 88 to 93 of the Fragmenta, containing numerous descriptions 
and notes of Australian flowering plants and ferns, there are 
several supplements dealing with lower Cryptogams. These 
include lists of the (1) Algz by Sonder, (2) Characeze by Braun, 
(3) Mosses by Hampe, (4) Hepatice by Gottsche, (5) Lichens 
by Krempelhuber, and (6) Fungi by M. C. Cooke. ED. 
MICROSCOPIC STRUCTURE OF SOME IGNEOUS DYKES OF 
NORTH GIPPSLAND.—The fourth number of the Journal of the 
Microscopical Society of Victoria contains an article on the 
“Microscopic Structure of some Igneous Dykes of North Gipps- — 
land,” by Mr. Howitt, which will be read with interest by all 
mineralogists, while Mr. Wooster has a valuable contribution to 
entomology entitled “How the Lerp Crystal Palace is built.” 
The other articles are taken up with mounting and cleaning 
of slides, etc., and are hardly up to par for a journal of the kind. 
CAPRELLINA NOVA-ZEALANDIA, G. WZ. Thomson.—From a 
letter received from Dr. Mayer, of the Zoological Station, 
Naples, who has been recently engaged in working out the 
Caprellidz, we learn that this singular crustacean has been 
already described by Nicolet as Caprella longicollis, from the 
coasts of Chili. This is not, however, C. longicollis of Lucas, 
described in the British Museum catalogue of Amphipoda (p. 
362) as occurring in Algeria, as the latter is a true Caprella. 
Dr. Mayer retains for our species the generic name of Caprellina, 
but alters the specific name to Nicolet’s. In the form of the 
mouth-organs, the branchiz (kzemer) and abdomen, Caprellina 
somewhat resembles Leach’s genus Proto. ED.
