tortuous. Their direction varied from horizontal or slightly upward 

 to vertically downward. 



I was not able in any case to demonstrate a special shelf on 

 which the animal rested, although the end of the burrow or of one of 

 the side branches might be enlarged into a chamber. 



Sometimes the crayfish was easilv caught without digging out the 

 entire burrow. If the entrance were opened out, and the open hand 

 placed in it in the muddy water, the crayfish usually came up into my 

 hand in a few minutes. 



The irregularis in the burrows is doubtless due to the burrows 

 having been constructed in different seasons and at times of different 

 water levels. Separate burrows would frequently become connected into 

 one, thus giving more than one opening. The variation shown in the 

 direction of the burrow would be caused by local differences in the 

 nature of the bank, the presence of stones and other hard materials. 



Burrows in the bed of a small stream running into the Credit 

 River near Port Credit, were found to contain the large species, C. 

 bartonii robustus. In this case also, there was no regularity in the 

 mode of construction. The majority of the openings were in the 

 middle of the bed of the stream and under water. This species does 

 not ordinarily burrow, but is to be found underneath large stones. The 

 scarcity of stones and the small size of the stream (drying up at 

 times?) doubtless forced the crayfish to burrow. 



BIRD NOTES. 



Occurrence or the Ring-necked Pheasant in the 

 vicinity of Montreal. 



At Dumouchel's taxidermy shop, on October 10, I saw a male 

 Ring-necked Pheasant in the flesh, which had been shot at Ormstown, 

 on October 8, by Mr. Dionne. Another bird seen at the same time, 

 concerning which I could obtain no data, was probably shot in the 

 vicinity of Montreal. The necks of both birds were distinctly ringed 

 with white. These are the first records I know of for this locality. 

 Birds Affected by Artificial Light. 



St. Lambert has recently acquired a new system of street lighting 

 which makes the streets much brighter than formerly. About 9 p.m. 

 on November 2, I heard a commotion in a maple tree and discovered 

 two European Sparrows amongst the foliage. I watched them for 

 several minutes, moving about and chirping quite naturally in the 

 brilliant glare of a neighboring lamp, with no apparent intention to 

 retire. It is well illustrated, in the 'gay white ways' of cities, how 

 man has been induced to turn night into dav, but this is the first 

 instance I have noticed amongst day-feeding birds. Perhaps it is 

 natural that the adaptive 'sparrow' should be the first to adopt this bad 

 habit. L. Mel. Terrill, St. Lambert, Que.
