may also perchance find the pupa of Selenia illustraria in a very 
slight cocoon. 
If you lever up the sods of grass and pull them to pieces you 
will be pretty certain to find in them Toeniocampa stabilis , T. cruda , 
and perhaps jnunda also. The other pupae you may find beneath 
oak trees, are, Notodonta chaonia; N dodonoea , and (if you have 
good luck), N. trepida; also, in their localities, the rare 
Nyssia hispid-aria , and the very rare Boarmia consortaria. Besides 
these, Tceniocampa mimosa sometimes turns up. 
Platypteryxp'alcula pupates in a slight web, inside a doubled up 
birch leaf; P. unguicula , in a slight web among beech leaves; 
Dicranura bicusMs in a compact gummy cocoon in the crevices 
of the bark of alder trees, generally about half way down ; D. 
furcula on sallow, not far from the ground ; D. bifida on aspen ; 
Notodonta camelina in a slight cocoon at roots of birch, maple and 
oak; N. cucullina beneath moss at roots of maple ; N. dictoea, 
beneath fallen leaves, to which the cocoon is attached, at roots of 
poplar and sallow ; N. dictoeoides and N. dromedarius should be 
sought beneath fallen leaves at roots of birch ; N. ziczac pupates 
in a slight cocoon on the surface of the ground at the foot of 
poplar and sallow.— a.h.w. 
CONCHOLOGICAL NOTES. 
The ordinary work for the season is to be considered over now, 
should the weather keep open, however, there will be found suffi¬ 
cient to keep the industrious conchologist on the warpath for 
some further time in sheltered places. For what I may term the 
“ butterfly” conchologist it must regretfully close. Do you know 
though, that some of us are anticipating what is perhaps the 
most pleasurable employment connected with the science ? I 
mean of course the winter work, i.e., enquiries into the burrow¬ 
ing habits of the mollusca, a department intimately connected 
with the welfare of the study, and a department which is I am 
sorry to say, very much over-looked. I have insisted on the 
necessity of good work being done in this province, many times, 
as indeed have others claiming to be conchologists, but, some¬ 
how, there seems a dearth of spirits able and willing to forsake 
their warm fire-side to make excursions (or incursions as they are 
very often) into nature. 
Let us see what can Be done among the readers of the Natura¬ 
lists' Journal, towards increasing our knowledge on the subject. 
In my notes, which will I hope follow monthly, I shall endeavour 
to show what can be discovered in this direction, meanwhile let 
those interested read a paper of mine which appeared in the August 
number of the Amateur Naturalist , on, “The Burrowing of the 
Mollusca.” I shall be pleased, to correspond, receive notes, and 
explain so far as lies in my power. The following want par¬ 
ticular attention :— Achatina acicula , Zonites crysiallinus, Succinea
