Teeth — in a transverse row across the head of the vomer, followed 

 by three more teeth placed in a single series along the anterior half of 

 the body of that bone ; this form of dentition being identical with 

 what has been previously described in other specimens, and showing 

 either that deciduous vomerine teeth may exist on the body of the 

 vomer in Char crossed by Trout : or else, that instead of a double 

 row of teeth along the body of the vomer, as seen in Trout, they 

 may be reduced to a few placed in a single row should such fish be 

 crossed with Char. Scales — 22 rows pass from the base of the 

 adipose dorsal downwards and forwards to the lateral line. Colours — 

 yellowish shot with purple and reticulated with irregular black 

 bands, spots, and markings along the body, but most spotted on the 

 upper surface of the head and back ; a few dark marks also on the 

 sides of the head. Dorsal fin yellow, with black spots and irregular 

 bands, the upper portion of its anterior edge being rather light with 

 a dark base. Adipose dorsal with a black base and two black spots 

 one above the other. Pectoral black-tipped. Anal with the three 

 first rays white, posterior to which the fin is stained with dark grey, 

 especially in its outer portion. Caudal dark-edged, and with a few 

 indistinct bars at its base. On opening the specimen, it was found 

 to be a male with the milt very fully developed. 



November 12, 1884. — Pond no. 3 at Howietoun was examined, 

 and the females of the Zebra race were not quite ready for breeding, 

 while they appeared to be fewer in number than the males, some of 

 which were ripe. A female Lochleven Trout furnished 13.50 eggs, 

 which were fertilized by the milt of one of the Zebras 8i inches 

 long, and placed in box 92 a. Should these eggs prove fertile the 

 young will be three parts Lochleven to one part American Char. 



August 28, 1882. — A hybrid 7| inches long was taken from 

 pond no. 4 at Howietoun from among about 90, all being in good 

 condition. These fish are the progeny of an American Char milted 

 from a Loch-Eannoch Char ^ November 15, 1882, and formerly 

 termed Salmo strvanensis, a dark variety of the common Char. 

 These hybrids are now distinguished as the Struari breed. The 

 following is a description of the specimen : —

^ The three Loch-Eannoch Char died during this summer. It would appe.ir 

 that at Howietoun the American Char at five years old has ceased to be com- 

 niercially paying as a breeder, while some even at four years old show signs of 

 senility.
