STOXE OX THE SACRAMENTO SALMON. 201 



of Lake Talioe tront and California hrook-tront, (Salmo iriclca.) The society has re- 

 ceived several orders recently from Australia and New Zealand for a large nnmher of 

 the eggs of the California Salmonida;. 



No. 3. Same as No. 2. 



No. 4. Lake Talioe trout. Commou name, (Talioe) "shore-trout." 

 Yearling-. August 16, 1872. Very abundant at Lake Talioe. This one 

 was hatclied artificially at the ponds of the California Acclimatizing 

 Society in April or May, 1871. Contributed by California Acclimatiz- 

 ing Society. 



No. 5. Same as No. 4. 



No. 6. Six specimens of young fry, hatched iu April, from parents taken 

 from San Andrea's reservoir, and reared at California Acclimatizing So- 

 ciety ponds. August 17, 1872. Contributed by California Acclimatizing 

 Society. 



No. 7. Six specimens of Califoruia brook-trout. San Pedro brook. 

 Young fry, August 17, 1S72. (See draAviug.) (See note.) 



No. S. Skin and head. Commou name, San Andrea's lo^ver reservoir 

 trout. Weight, 8 pounds. Length, 2G inches. Girth, (just in front of 

 dorsal.) 17 iuches. Peculiar to the lower reservoir of the San Andrea's 

 (" Spring Valley") water-works. (See note.) The fattest and heaviest 

 trout of its length that I ever saw. Easily lauded, and died very quickl}'. 

 There were about 500 separated and fully-develoi)ed eggs of last spring's 

 roe lying loosely in the abdomen. The natural spawn of the next sea- 

 son were quite small — iierhaps the size of pin-heads. This fish is rare, 

 and is the only large tro&t caught in the lake. Silvery. No colored 

 spots. Caught with chub bait. August 20, 1872. 



No. 8. This vras a fine specimen of its kind, and one of the largest ever taken. The 

 "reservoir" in which it was caught is an artificial hpdy of water, several miles long, 

 formed by building a dam across the San Andrea's brook, and used to supply the city of 

 San Francisco with water. The appearance of this fish in the reservoir was a sur- 

 prise, as no fish of that size had ever been known about there before. It is thought 

 by some to be a salmon, accidentally shut iu from the sea by the dam, and by others 

 to be a trout, which favorable circumstances bring to this unusual size. The reser- 

 voir absolutely swarms with chilis, about six or eight inches long, which form the 

 food of these large fishes. It is a singular fact that the upper reservoir, a short dis- 

 tance above on the same stream, contains only the common trout of the usual size. 



No. 9. Silver trout. San Andrea's lower reservoir. Eather rare. Very 

 much resembles salmon smolt. Never caught large. Beautiful form. 



No. 10. Viscera of No. 8. 



No. 11. Two specimens. Utah mountain-trout. Young fry. Salt 

 Lake City trout-ponds. Hatched artificially. Parents taken in Bear 

 Eiver. Abundant in Bear Eiver and Bear Lake, and other cold mount- 

 ain waters in Utah. Hatched in April, May. Period of incubation, 

 very short. August 9, 1872. (See note.) Contributed by A. P. Eock- 

 woocl, superintendent fisheries Salt Lake City.
