teeth and its slender build, whilst the second is distinguished 

 by the shortness of these teeth and the elongation of the limbs. 

 So perfectly are the remains of Stenomylus preserved in the 

 quarry on the Niobrara River, Nebraska, which takes its name 

 from the genus, that it has been found practicable to mount a 

 complete skeleton for the Carnegie Museum. This has been 

 described in the Annals of the Carnegie Museum, vol. vii. pp. 

 267-73, by Mr. Peterson, who, on account of certain pecu- 

 liarities in the skull, regards the genus as indicating a special 

 group of the family. He also considers it to be an immigrant 

 into the Niobrara district, where it became modified in 

 accordance with the upland nature of its environment. 



In a second communication the same writer {op. cit. pp. 

 260-66) describes a beautifully preserved skull and other 

 remains of a new species of Oxydactylus from the Miocene of 

 Western Nebraska. 



The discovery in the autumn of 1907 of mummified car- 

 cases of mammoths and rhinoceroses in the ozokerit deposits 

 of the Starunia district of Eastern Galicia gave rise to con- 

 siderable interest at the time. The specimens, after being 

 carefully disinterred, were transferred to the museum at 

 Lemberg, where the skin of the rhinoceros has been set up 

 and an illustrated account of both specimens, by Mr. E. L. 

 Niezabitowski, is published in the Anzeiger d. Akad. d. 

 Wissenschaften in Krakau (191 1, pp. 229-39 an ^ 240-66). The 

 rhinoceros, which belongs to the woolly species {Rhinoceros 

 antiquitatis), is so well preserved that the author has been 

 enabled to compare the head in detail with that of its nearest 

 relative, the existing white rhinoceros of Africa. The species 

 presenting the next nearest relationship appears to be the 

 European Pleistocene R. mercki. The hair of the Starunia 

 rhinoceros had disappeared, probably owing to the action of 

 the ozokerit. 



This is, however, by no means the only memoir on fossil 

 rhinoceroses, for, although dated 1910, copies of one by Dr. 

 O. Abel on the early European Tertiary species published as 

 part 3 of vol. xx. of Abhandlungen der k.k. Geologischen 

 Reich sanstalt, did not reach this country till 191 1. The author 

 adopts the view that the rhinoceros-group should be divided 

 into the families Hyracodontidce (including Hyrachyus as well as 

 Hyracodon), Amynodontidce, and Rhinocerotidce, each of which
