io8 BRITISH FRESHWATER FISHES 



Drumlane in Cavan, and Loughnabrach in Long- 

 ford, none of which are very far from Lough 

 Owel.

 (d), showing the difference in length and number of the gill-rakers. 



The Coomasaharn Char {Sahelinus fimbriatus) 

 takes its specific name (^fimbriatus, fringed) from the 

 long and numerous gill-rakers. In other Irish Char 

 eleven to sixteen may be counted on the lower limb 

 of the anterior branchial arch, but in this species 

 eighteen or nineteen. This form is known only 

 from a single female example, 6 inches long, from 

 Lough Coomasaharn in Kerry ; it is very similar to 



Fig. 14. — Head of Coomasaharn Char, 



Cole's Char, but has the interorbital region flatter 

 and narrower, its width only a little more than one- 

 fourth of the length of the head.
