Notes on Birds wintering around Montreal, 425 



impressed by the resemblance between the form of tbe cheek 

 and small needle-shaped posterior spines of C. minutus and the 

 same parts of the head of the Quebec species which I have 

 called Menocephalus glohosus, and it appears to me that Menocepli- 

 alus must be regarded as another closely allied genus. If we 

 except those two genera, Calymene and Menocephalus^ there is 

 no other but Conocephalites to which our new trilobite bears any 

 near affinity. 



Mr. Bradley has since the publication of the above received a 

 collection of Fossils from the Potsdam sandstone of the western 

 states among which are several specimens of C. minutus. They 

 were collected at a place called Black River Falls in Wisconsin 

 where they occur associated with several of the species described 

 by Dale Owen.

ARTICLE LI. — Notes on Birds wintering in and around Mon- 

 treal, From observations taken during the winters of 1856- 

 57-58-59-60. By H. G. Vennor, junr. 



Few of our birds can endure the severe winters we generally 

 have in this part of Canada. Soon as the icy breath of that 

 hoary season is felt, and often long before, our feathered song- 

 sters hasten to their southern feeding grounds. A few, how- 

 ever, that seem loath to leave their summer haunts, loiter about 

 until winter has come in reality, and then, as if aware that they 

 have been imprudent, haste away in the same direction. These 

 are our loiterers, and must not be confounded with our real winter 

 residents. Others again, bid defiance to the severity of winter, 

 and remain eagerly searching for their food, in the bare, and 

 now apparently lifeless trees. It is to this class of birds, that I 

 have, for the last foui* winters, turned my attention. 



Again, there are a few birds which come from the North every 

 winter, and return thither as soon as the cold weather leaves us. 

 The Pine Grosbeak, Bohemian Wax-wing, and common Snow-bunt- 

 ing, are examples. For this reason, it is difficult to make out an 

 accurate list of the birds which remain here the whole year round, 

 and unless the observations extend over several winters, it is al- 

 most impossible. On comparing my notes of the last nve winters, 

 I find that the list of birds varies every winter, as the weather has
