 enough is furnished to show the grand scheme which Professor

GEOLOGY AND PALAEONTOLOGY. 



Mammalia in the Laramie Formation.— Mammalia, which 

 have been so long looked for in vain in the Laramie beds, have 

 at length been found. Mr. J. L. Wortman, who was sent to ex- 

 plore this formation the past season, was instructed to look espe- 

 cially for Mammalian remains. He now announces that he has 

 found them in place and mingled with Dinosaurian remains in 

 such a manner as to admit of no doubt of their contemporaneity. 

 Two species have come to hand, of which the following only is 

 determinable . 



Mciiiscocssus conquistus, gen. et sp. nov. — But one specimen of 

 this animal was found, and that is represented by two molar teeth 

 and a distal extremity of a humerus. Were it not for the asso- 

 ciated molar tooth, I should think that the second tooth might 

 be that of a herbivorous reptile. It is probably a fourth pre- 

 molar of the general type of that of the PlagiaulacidcE. 



Char, gen.— Fourth premolar with a compressed anteroposte- 

 rior edge, which is studded with denticles; sides without ridges. 

 Posterior molar rather small; crown with three longitudinal 

 series of tubercles, of which many have crescentic sections. 



This form is plainly not a distant relative of the Piagiaulactao, 

 recently described in the Naturalist, from the Puerco f-ocene 

 of New Mexico, and it may enter that family. Its molar has the 

 same number of rows of cusps as in Polymastodon Cope, ine 

 tooth is, however, of especial interest from its resembl 

 molar of the genus Stereognalhns Owen, from the Oolite of Lng- 

 land, showing clearly that that genus, whose affinities have been 

 hitherto unknown, must be referred to the neighborhood ot trie 

 Plagiaulax of the same great Jurassic period. The humeral con- 

 dyles have the remarkable characters of those of Catopsahs.
