NOMENCLATIVE AND MORPHOLOGY. 107 



Champlain and several lakes in New York, and which also ex- 

 tends further south, has been introduced into Great Sandy Lake 

 in Wareham. In the summer of 1862 a specimen of this fish 

 was caught in Massachusetts Bay by one of the members of the 

 state legislature, and is now in the state cabinet. The fish had 

 evidently found the salt water not much to its liking, as it was 

 much emaciated, and had changed so in its general appearance 

 as at first sight hardly to be recognized." (PUTNAM, Storer's 

 Fishes Mass. 278, 1867.) 



MICROPTERUS FASCIATUS Cope, 1868. " This specimen is 

 abundant in Holston River; individuals are identical with others 

 from Miami River; Indiana; Wabash; Kiskiminitas ; from 

 Michigan and Lake George, N. Y. It grows to a considerable 

 size and is much valued for food. 



"The absence or rarity of this species and the Ambloplites 

 rupestris in the Kanawha River, in Giles County and above is 

 remarkable. During a residence of six weeks on its banks, I 

 never caught or saw a specimen of either, and they are not 

 clearly known to the fishermen." (COPE, Jour. Ac. Nat. Sd. 

 Phil. VI, 216, 1868.) 



MICROPTERUS SALMOIDES Gill, 1873. " Scales small, in about 

 70 to 80 oblique rows between the head and caudal, and 11 long- 

 itudinal ones between the back and lateral line, decreasing very 

 much towards the nape and (especially) the breast ; forming a 

 sheath encroaching considerably upwards upon the. soft portion 

 and last spine of the dorsal. . Head transversely (slightly) 

 convex between the orbits, with (1) scales on the operculum 

 larger than those of the nape, (2) on the suboperculum (in 

 front) in two rows, (3) on the interoperculum narrow, mostly in- 

 vested in the membrane (in one row), (4) on the cheeks very 

 small (in about 17 to 20 rows), and (5) on the preoperculum 

 none. Mouth moderate, the gape from the symphysis to the 

 angle being little more than one-third (1 : 2J-) of the head's 

 length. Supramaxillary ending in advance of vertical from the
