The common herring of the Gulf of St. Lawrence, and of the 

 Atlantic Coast of N. America, is looked upon as identical with 

 the European species ; and, as Dr. Gunther states positively that 

 whitebait are young herrings, there would seem to be no reason 

 why this delicacy should not be procurable in Eastern Canada. 



We notice also that in Dr. Gunther's Catalogue of the Tail-less 

 Batrachians of the British Museum, he considers that the Rana 

 sylvatica of Leconte, a land frog which is frequent on Montreal 

 mountain and elsewhere in Lower Canada, is only a variety of 

 the commonest European frog, the Rana temporaria. 



Recent investigations have shewn that the late Prof. E. Forbes' 

 theory that animal life would not be found at great depths in the 

 sea is untenable. Living examples of all the great divisions of 

 the invertebrata have been taken at depths of over one hundred 

 fathoms outside of the Florida reef, and crustaceans, annelids 

 and radiates were dredged in 517 fathoms water in the same 

 locality. Researches off the Coasts of Portugal and Norway give 

 similar results, as also do the investigations of Dr. Carpenter and 

 Prof. Wyville Thompson, off the Faroe Islands, and quite a new 

 zone of animal life has been thus recently revealed to us. J. F. W. 



A Butterfly Parasite. — At a meeting of the Montreal 

 Microscopic Club, one of the members exhibited specimens of a 

 vegetable parasite on the tibia and tarsus of the dark swallow- 

 tailed Butterfly, Papilio A^terias. The insect was captured at 

 Brantford, Ont,, last summer, along with three other specimens, 

 at the same time and place. The parasite was only found on one 

 of these, growing on the spines of the tibia, tarsus and tips of the 

 ungues. Attention is at present directed to the circumstance, and 

 a full description will be given in the next number of this journal. 



Mosquitoes in England. — Most of the readers of The Natur- 

 alist will remember the outcry last summer in reference to the
