break up into fragments, some of which would afterwards form 
themselves into revolving little wheels with cilia, which gave me the 
impression that the particles were starting on a new round of ex- 
istence as separate individual organisms; and were there facilities 
at some subsequent time for observing their strange evolutions, I 
am of the opinion that light might be thrown on modes of repro- 
duction concerning this and perhaps of other allied groups of the 
Ceelenterates. But this fact itself, so far as observed, requires 
to be mentioned with caution, unless it be a matter which has 
already, unknown to me, engaged the attention of biologists. 
Ornithologists who would like to know more about birds of 
the Frozen North region visited by Mr. Halkett, are referred to a 
special article on the subject by the Rev. C. W. G. Eifrig, in 
The Auk, for July last, pp. 233-241, entitled: ‘‘ Ornithological 
Results of the Canadian ‘ Neptune’ Expedition to Hudson Bay 
and Northward, 1903-1904.” 
SVAENOPIS (HEPIALOS ) THOLE,: STRECKER, AT 
OTTAWA. 
By ARTHUR GIBSON, Central Experimental Farm, Ottawa. 
The discovery of this rare and extremely local moth at Otta- 
wa during the past season is very remarkable. The only known 
definite locality of this insect, as far as we know, is Montreal, 
Canada, where the moths in some years are taken not uncom- 
monly. The presence, therefore, of the species at Ottawa is most 
interesting and worthy of special notice. 
On the 6th July, 1g05, Dr. Fletcher, Mr. J. W. Baldwin and 
the writer spent the evening collecting moths around the electric 
lights close to the entrance to the Experimental Farm. The 
night was a rather good one for the purpose, and it was a little 
late when Mr. Baldwin and I started in to the city, for our res. 
pective homes. At the southern end of LeBreton Street, where 
there is an electric light, we stopped for a moment, and, just as 
we did so, I noticed a large moth fly quickly past and settle on 
the road a short distance away. A few seconds later it was safe
