GENERAL NOTES. 229 
A number of useful practical hints are given in the introduc- 
tion, and methods of preparing the skeletons of the types are in- 
cluded in the text. The author strongly advises students to 
make sketches of their dissections, and this advice we can heartily 
endorse. “ Even a rough drawing, if the various parts are pro- 
perly named—and especially if they are further distinguished by 
different colours, forms a far better memorandum of work done 
than any mere description.” 
In one respect we think that the book might have been ren- 
dered more complete and more useful. In Huxley and Martin’s 
“Elementary Biology” the laboratory work in each section is 
preceded by a general description of the plant or animal under 
consideration. In this a number of interesting facts with regard 
to the habits of life, the more important points connected with 
the physiology and development of the type, &c., are given, and 
the morphological significance of certain structures pointed out. 
In the present work, however, each type is considered without 
reference to the others, and with regard to its anatomy only— 
the book is, in fact, only a manual of “ Directions for Dissection.” 
We are aware that the author did not intend the book to be 
more than this; but he has carried out his plan in so clear and 
admirable a manner that we should have liked to have had more 
from him. Whilst we are grateful to the author for all that he 
has given us, we think that an opportunity has been lost of im- 
parting a good deal of valuable knowledge, which would have 
aided the student and lent an additional interest to the subject. 
The various types in the progressive series might have been com- 
pared, and the modifications pointed out which certain structures 
have undergone in the progression to higher or more specialised 
forms. In this way the morphological bearing of seemingly un- 
important details would have been obvious, and the dry facts of 
anatomy have received their savour from the “ salt of morpholo- 
gical ideas,” a savour which, at present, is not apparent to the 
beginner, who will, therefore, have to derive it from other sources. 
Although we think that the book would have been rendered 
inore valuable by the additions suggested, we have no hesitation 
in recognising it as a most valuable practical guide, and feel as- 
sured that it will meet with a ready welcome in every zoological 
laboratory.

INTRODUCED Motus IN NEW ZEALAND.—During last 
summer Mr. R. S. Allan, while engaged in some survey work in 
connection with the Wellington-Manawatu railway, sent me 
down several specimens of moths collected by him near Porirua. 
At first I took these to be Hymenopterous insects, but finding 
on closer examination that they were true Lepidoptera, I for- 
warded them to Mr. E. Meyrick, who gives me the following infor-
