Lophiiis piscatovius is characterised by having associated 

 with it a special parasite, which is attached in consider- 

 able numbers to the gills and the branchial pouches. 

 Attention was first directed to this parasite, so long ago 

 as 1835, by Dr George Johnston of Berwick. It has sub- 

 sequently been seen and described by other naturalists, 

 and has been referred to the genus Chondr acanthus, species 

 lophii, a parasitic crustacean. I first saw this parasite in 

 1861, in a small specimen of Lophins captured at Whitby 

 in Yorkshire, and in conjunction with Dr H. S. Wilson 

 I gave an account of its structure in the Transactions of the 

 Royal Society of Edinburgh of the following year. Large 

 numbers of this parasite were also attached to the gills and 

 branchial pouches of the Loch Goil Lophins. 



Montagu's Harrier in North Wales. 



By H. E. Forrest. 



Montagu's Harrier obtains its trivial name from Colonel 

 Montagu, who did so much for the ornithology of Britain 

 eighty years ago. He it was who distinguished this from the 

 closely-allied Hen Harrier, and bestowed on it the distinctive 

 title Circles cincraccus (ash-coloured Harrier). 



It is distinguished from the Hen Harrier by its more 

 slender build and longer wings, which, when closed, reach 

 to the end of the tail. The male is further distinguished by 

 having a dark bar across the wings, which is not found in the 

 other species. Mr Howard Saunders points out that either 

 sex, at any age, may be distinguished from other members 

 of the genus by the fifth primary not being emarginate on its 

 outer web. 



In both C. cyaneiis and cincraccus the adult male is of a 

 pale grey colour, though the female is brown. The young 

 of both sexes are brown. At the time of writing I have just
