ZOOLOGY. 



The Lough Finn Char (Salvelinus Trevelyani). 



Two years ago I described the Char of Lough Finn, in Donegal, from 

 a single male specimen, 8 inches long, sent to me by Major H. Trevelyan, 

 after whom I named the species. From males of the allied form inhabit- 

 ing Lough Kask {Salvelinus Colli, Giinth.), this fish differs in the longer 

 head, more produced and pointed snout, narrower interorbital region, 

 longer lower jaw and stronger dentition. 



I am indebted to Captain J. S. Hamilton for a second example of S. 

 Trevelyaui, a female of 6^ inches. It was caught in Lough Finn on July 

 3rd, at about 3 in the afternoon, and was taken with a fly in shallow 

 water near the shore at the mouth of a small stream. 



This specimen shows that in S. Trevelyani the sexes are distinguished 

 by well-marked external characters, for the head is shorter, the snout 

 blunter, the lower jaw shorter, and the teeth much weaker than in the 

 type, although the fins are not less developed. The differences between 

 the Char of Loughs Finn and Eask are less marked in the females 

 than in the males. The following measurements (in millimetres) may 

 have some interest: —

The Jay in Queen's County. 



Having been in Mountrath an<l the neighbourhood of Abbeyleix, 

 Queen's County, for some time I noticed an abundance of Jays ((7a;v7////j- 

 glanJaritis). They are well known to reside in those counties watered by 

 the Nore, but, a gentleman who has lived for years in Queen's County, 

 informs me they have never been seen so numerous before. Does not this 

 seem as if this bird is rapidly spreading and becoming more common .''
