the Lough Melvin char, however, it is ahnost impossible to 

 distinguish the sexes from external characters/ as was recog- 

 nised so long ago as 1841 by Thompson, who wrote "some 

 of the largest-finned are females." Thompson also noted that 

 this form differed from other char in its dull coloration, pale 

 flesh and insipid taste. 



A single specimen, eight inches in length, from Lough 

 Finn, in Donegal, differs so notably from S. Colii as to war- 

 rant me in describing it as a new species, which I have named 

 after the donor. Major H. Trevelyan. Salvelimis Trevelyani 

 is especially distinguished from 5. Colii by the produced 

 pointed snout and strong dentition.

A second new vSpecies from Lough Owel, in Westmeath, 

 named after Dr. R. F. Scharff, is known from a single speci- 

 men, nearly a foot long, in the collection of the Dublin 

 Museum. The scales, which number 186 in a longitudinal 

 series, are considerably smaller than in 6*. Colii, from which 

 Salvelimis Scha7[ffi differs also in the conical snout, oblique 

 mouth, &c. 



1 In a recent article on Irish char in the Field, ^Ir. G. A. Boulenger 

 states that in S. Grayi the males have the pectoral fins longer than the 

 females. This is contrary to the observations of Thompson (1841) and 

 Giinther {P.Z.S., 1863, p.12) ; the female specimen mentioned by the 

 latter is still the only one of that sex in the British Museum collection, 

 and has a longer pectoral fin than several of the males. The measure- 

 ments given b)^ Mr. Boulenger, in order to show the supposed difference 

 between the sexes, appear actually to be taken from GUnther's two 

 tvpe specimens, both of which are males.
