All important lot of Basiloscmni.s- cetaules remains, including 

 the types of Pterosphenus schucherti (Lucas, F. A., Proc. U. S. Nat. 

 Mns., vol. 21, p. 637, 1898) and Hadrianus schucherti (Hay, O. P., 

 Proc. U. S. Nat. Mus., vol. 22, p. 22, 1899) , was collected for the Museum 

 from the Jackson (Eocene) of Alabama by Charles Schuchert. This 

 material supplemented the collection made in 1894, and from the two 

 collections a skeleton was mounted for exhibition (Gidley, J. W., Proc. 

 U. S. Nat Mus., vol. 44, p. 649, 1913 ; also described by R. Kellogg, 

 Carnegie Inst. Washington Publ. 482, 1936). In exchange with Dr. PI. 

 Crediier, a collection of amphibians came from near Dresden, Germany. 



1897 



A fine example of a fossil ray, Xiphotrygon acutidens^ from the 

 Green River shales of Wyoming was purchased from R. L. Craig. 



The types of Heterodontosuchus ganei from the Triassic of southern 

 Utah, and of Dinictls major from the Oligocene of western Nebraska, 

 described by F. A. Lucas (Amer. Journ. Sci., ser. 4, vol. 6, pp. 399-400, 

 1898), were transferred from the United States Geological Survey. 



1898 



An important collection of fossil fishes made by the Hay den sui'veys

 cipally in Rep. U. S. Geol. Surv. Terr., vol. 3, 1884) . 



A skull and lower jaws, with associated fore limbs and feet and skin 

 impressions, of Thespesius ann^ctens, from the Lance, Upper Creta- 

 ceous near Forsyth, Mont., were purchased from Robert Butler. The 

 skin impressions were described by J. B. Hatcher (Ann. Carnegie Mus.. 

 vol. 1, p. 130, fig, 1, 1901) as CJaosaurm. 



The type specimen of Hoplitosofurus mars hi collected by N. H. Dar-
