the average, and weighed many times as much as they did when received. None of 

 them at any time showed a red lateral band such as is present in the Rainbow, and 

 they are farther distinguished by the presence of white tips on the ventral and anal 

 fins; the dorsal also has a small white tip. They have been kept almost from their 

 arrival in salt water, and could not have been kept in the warm Croton water in 

 June. The salt water never rose above 713^2° F. and continued at this high tem- 

 perature only 10 days. 



The N. Y. Fisheries, Game and Forest Commission planted some of these trout 

 in a Long Island stream and some in a lake in Northern New York. Those that 

 were planted on Long Island, says Mr. Cheney, when rather more than a year old 

 rose to the fly of the trout fisherman and made a most gallant fight, but it is too 

 early to tell the outcome of the experiment. The eggs are one-fifth of an inch in 

 diameter: they hatch in 42 to 50 days with water at 50°.

The Brown Trout of Europe was introduced into the United States from 

 Germany in February, 1883, and in subsequent years ; it has now become thoroughly 

 acclimated in the fresh waters of many of the States. 



The body of this trout is comparatively short and stout, its greatest depth being 

 contained about four times in the length without tlie caudal. The caudal peduncle 

 is short and deep, its depth equal to two-fifths of the length of the head. The 

 length of the head in adults is one-fourth of the total length without caudal or 

 slightly less. The diameter of the eye is about one-fifth of the length of the head, 

 and less than length of snout. The dorsal fin is placed nearer to the tip of the snout 

 than to tlie root of the tail ; the longest ray of this fin equals the distance from the
