Jordan and Evermann. — Fishes of North America. 507 



are often nearly plain bright silvery. Many local varieties distinguished 

 l>y shades of color, also occur. Length 18 inches or less. The best known 

 of our charrs, abounding in all clear, cold streams from Maine to the 

 Saskatchewan and northward to Labrador, southward in the Alleghaniea 

 to the head waters of the Savannah, Cliattahoochee, Catawba, and French 

 Broad; largely introduced into western streams but not native west of 

 the Mississippi. {foutinaJis, living in springs.)

Represented in certain ponds in New Hampshire by 



783a. SALVELINUS FONTIXALIS AGASSIZIIf (Garman). 



(Dublin Pond Trout.) 



Coloration pale grayish, almost without red spots, thus resembling the 

 lake trout. Otherwise similar to fontinalis. (Named for Louis Agassiz.)

784. SALTELIXI'S MALMA (Walbaum). 

 (Dolly Varpen Tkout ; Oregon Charr ; Bull Tbout ; Red-spotted Trout ; Malma ; Golet.) 



Head3f; depth 4; eye 4i. D. 11; A. 9; scales 39-240-36 ; pyloric ctpca 

 large, 45 to 50 ; gill rakers about 8 + 12. Body stout, the back somewhat 



* Sea-run forms of this and other charrs and trout are larger in size, silver-gray in color and 

 without spots, or nearly so. A silvery-gray form almndaut in Canadian estuaries, and locally 

 known as Salmon Trout, has been called var. immacnUUiis, but this name is preoccupied by Salmo 

 imiiianiliilus, Walbaum, which is one of the Characinidse. 



+ This form is thus described bv Mr. Garman : 



Salmo aqasshii: B. 11 to 13; D. 12 to 13; A. 10 to 12; V. 8 to 9; P. 14 to 15; pores 109 to 119; 

 scales 38 to 42-217 to 237-38 to 42; second dorsal to lateral line, 28. 



A variety of the brook trout; apparently restricted to the email lakes in the neighborhood of 

 Dublin, New Hampshire. Comiiari'd with those of b'. foiiHualis, the young are rather more slender, 

 the caudal notch slightly deeper, and the sides more silvery. The young aro much darker 

 colored than the adults; on both the red spots of the Hanks are large and numerous. On the 

 adult the brown color has become so much bleached that the specimen is nearly uniform silvery; 

 very faint indications of the rod spots remain. The differences between the young of S. fnnlhialis 

 and those of this variety are even moxe marked than those between adults; side by side, the 

 clouded parr marks or bands at once disthiguish the young of S. agassi.-.ii. Apparently it is later 

 in attaining sexual development, and has the ajipearance of a deep-water species. Length 734 

 inches. 



Snout longer than eye ; maxillary extending behind orbit ; in young the diametet of the eye equals 

 the length of the snout, and the'length of'^the head is one-fourth of the total, without caudal; 

 the length of the head of a 12'., -inch specimen (fig. 18) e(iualsthe de|ith (if the body, and is con- 

 taini'd 4'^ times in the length of the body and head. Dublin Pond; Lake Mouadnock, Keene, 

 New Hampshire; Center Pond.
