inches long, precisely resembling in form and the position of the fins, the moun- 

 tain or specklrtd trout of the United States, except that the specks of the former 

 are of a deep black, while those of the latter are of a red or gold color : they 

 have long sharp teeth on the palate and tongue, and generally a small speck of 

 red on each side behind the front ventral fins ; the flesh is of a pale yellowish 

 red, or when in good order, of a rose colored red." London edition of 1814, p. 

 192, 4to. A.nd further on, page 487, we read: "The mountain or speckled 

 trout are found in the waters of the Columbia within the mountains ; they are 

 the same with those found in the upper part of the Missouri, but are not so 

 abundant in the Columbia as in that river. We never saw this fish below the 

 mountains, but from the transparency and coldness of the Kooskoskee, we should 

 not doubt of its existence in that stream as low as its junction with the south 

 east branch of the Columbia." 



It would be an interesting point to compare, side by side, specimens caught 

 in the Columbia, with those of the Missouri river. We should not be surprised 

 if the result of such a composition should refer the specimens from the basin of 

 the Columbia to Fario gairdneri. 



Specimens of this species were collected at the Falls of the Missouri River, 

 Rocky Mountains, by Dr. Geo. Suckley, U. S. A., under Gov. I. I. Stevens. 



2. Salar virginalis, Grd. Body subfusiform in profile, otherwise compressed; 

 head comprised about four times in the length, the caudal fin excluded. Jaws 

 subequal ; posterior extremity of maxillary extending to a vertical line inter- 

 secting the posterior rim of the orbit. Anterior margin of dorsal nearer the 

 extremity of the snout than the insertion of the caudal fin. Greyish brown 

 above with a purplish reflection and subcircular black spots ; beneath, olivaceous, 

 unicolor. 



Specimens collected by the party under Lt. Beckwith, in Utah creek, and at 

 Sangre de Cristo Pass, upper waters of the Rio Grande del Norte (Rio Bravo). 



3. Salar iridea, Grd. Sal-mo iridea, Gibbons, Proc. Cal. Acad. Nat. Sc. i. 

 1855, 36. Salmo rivularis, Ayres, Proc. Cal. Acad. Nat. Sc. i, 1855, 43. Body 

 subfusiform in profile, otherwise compressed ; head well developed, constituting 

 a little less than the fourth of the total length. Jaws subequal; posterior ex- 

 tremity of maxillary extending a little beyond the orbit. Anterior margin of 

 dorsal fin equidistant between the snout and the insertion of the caudal. Red- 

 dish brown above, with small and numerous black spots ; yellowish white 

 beneath. 



Specimens were collected in the headwaters of San Matteo Creek, Cal., by R. 

 D. Cutts ; at Petaluma, Cal. by E. Samuels, near Humboldt Bay, by Lt. W. P. 

 Trowbridge, and finally specimens obtained by Dr. Ayres, of San Francisco, 

 under the name of Salmo rivularis, proved identical with Salmo iridea, of Dr. 

 Gibbons. Dr. Gibbons' description was drawn from a very immature specimen, 

 but has the priority over Dr. Ayres's appellation. The aspect of the male is 

 quite diS'erent from that of the female, so that their identification requires a 

 very close study of their intrinsic characters.

 Cook of the State Geological Survey under the direction of Dr. W. Kitchell. 



Macrophoca, Leidy. 



1. Macrophoca atlantica, Leidy. 



Based upon three specimens of molar teeth, obtained by E. Davis, Esq., from 

 the miocene marl of Cumberland County. Genus belonging to the Zeuglodont 

 family. 



Crowns of the molar teeth broader than the length, laterally compressed coni- 

 cal ; anterior and posterior borders acute, the former with a series of two and the 

 latter with four conical tubercles having denticulated borders ; inner and outer
