the nose or mouth of their hosts." That this attack is pre- 

 judicial is evident by the fact that "if a Deer is attacked by 

 many flies, soon, one after the other, its nose bleeds, and the 

 mucous skin becomes very much inflamed. When the larval 

 growth is nearly complete, — that is, at the third stage, — the 

 maggots are to be found in the cavity of the mouth, or at the 

 palate, the Eustachian tube, and other localities, as parts of the 

 tongue and gullet." It is doubtful whether this attack is really 

 new in our country, or whether its discovery is now due to the 

 increased attention given to entomological research. Another 

 " Deer Forest Fly," Lipoptema cervi, of which males and females 

 are to be found in wingless condition on the Red and the Roe 

 Deer r has been found by Mr. Dugald Campbell (Strathconan 

 Forest, Muir of Ord) " to be very troublesome to those employed 

 in flaying Deer in winter, by reason of their creeping rapidly 

 about the clothes and into the hair of the workers, and being 

 very difficult to dislodge." To the Deer themselves, however, 

 this insect's presence is of no great consequence. 



Perhaps to the readers of ' The Zoologist ' these extracts may 

 prove most interesting, and we do not refer to the larger portion 

 of the Report devoted to the insect ravages on our vegetable 

 crops. In conclusion, we can not only recommend its perusal to 

 all who are interested in the details of our country life, but also 

 advise them to communicate with Miss Ormerod as to any insect 

 infestations with which they may become specially acquainted.

The first part of Section Aves, in the great descriptive 

 Zoological Encyclopaedia, has reached our hands, and is written 

 by Mr. Ernst Hartert, of the Tring Museum. The importance 

 of this work, and the way in which it will be probably consulted, 

 quoted, and followed in the future, must not be underrated. Its 

 proposed aim is nothing less than a synoptical description of the 

 described forms of animal life. It is, perhaps, too much to
