564 ON THE INTEODUCTION OP TROUT AND TENCH INTO INBIA. 



tity of mud washed in heavy rains from the cultivated land on 

 the east side of the Hills will, I fear, render the streams unfit 

 for Trout. "We caught several Tench weighing about 1| pound, 

 and Kudd* still heavier." 



Mr. H. S. Thomas, of the Madras Civil Service, wrote to me 

 (Jan. 8th, 1876) saying he was despatching a Neilgherry Trout. 

 " It was sent by Mr. M'lvor iu spirit to Mr. Ballard, by whom it 

 was immediately forwarded to me, and overtook me at Coonoor, 

 just as I was going down the Ghat. I took a hurried look for 

 the adipose fin, wrapped him in muslin, and replaced him again 

 in the spirit. The red spots were then bright ; a week later 

 they had almost disappeared. I mention this to show that he 

 was clearly fresh when he came to me, and to draw your atten- 

 tion to the spots being red, — this latter point, because Mr. M'lvor 

 told me that, with one solitary exception, the Trout he put into 

 the rivers were all Loch-Leven Trout ; in Loch Leven, accord- 

 ing to Mr. C. Pennell, the Trout have not red spots. Still the 

 spots may have been due to their having been bred in a river, not 

 a lake, for a series of years. 



The specimen weighed, out of spirit, \\ ounce. Length, from 

 nose to bifurcation of tail, 6 inches, to end of tail 6| inches. 



Salmo levenensis, Walker, Yarrell. — Loch-Leven Trout, Richard- 

 son. — Salmo csecifer, Parnell. 



D. 13; A. 11 ; L. 1. 120; L. tr. 26/30. 



Length of head 4|, of caudal 6f ; height of body 5| in the total length. 

 Eyes, diameter \ of length of head, 1 diameter from end of snout, and 

 Ij apart. The width of the head equals its length behind the eyes ; 

 its height equals its length, excluding the snout. Thirteen rows of 

 scales between the lateral line and the base of the adipose dorsal fin . 



This fish having been well described, it is useless to enter fully 

 on that subject. Respecting its colour, it shows twelve short, 

 vertical, light bars along the middle of the side, or the finger- 

 marks of a young fish. The spots alluded to are now black, 

 whilst Mr. Thomas observes that they were originally red. This 

 is probably due to the fish having been bred in a clear moun- 

 tain-stream ; for the Loch-Leven Trout are said to have no red 

 spots. The colour of the water and the soil through which 

 streams flow exercise great influence on the colours of fishes ; but 

 the result in this instance is most interesting. 



* I think these were Gold Carp. The single specimen I saw was Carassius 

 aiirafus.
