Altogether, the resemblances between these two forms are funda- 

 mentaC the differences are mainly such as separate many lower 

 Eocene from middle Miocene forms. Although no intermediate forms 

 are known, there is a presumption in favor of a genetic relationship. 

 At all events Meniscotherium will probably be removed from the 

 Condylarthra, where it has always held an anomalous position 

 and be placed in the Chalicotheriodea.— Henry F. Osborn, Ameri- 

 can Museum of Natural History. May 3rd, 1892. 



Geological News.— General.— In a preliminary paper on the 

 Ouachita Mountain System in Indian Territory, Mr. Robt. T. Hill 

 remarks that these mountains should no longer be omitted from our 

 maps, for they constitute the foundation of all later geologic structure 

 in the Texas region, differentiating it from the Kanaw-Miasouri 

 region in both present and past geologic times back to the earlier 

 Mesozoic epochs, and influencing all the main river courses of Indian 

 Territory whose great southward bends are an adaptation to the strike 

 of this mountain system, the Washita alone having cut through it, 

 (Am. Journ. Sci., Aug., 1891). Paleozoic-Mr. M. E. Wads- 

 worth announces that the recent observation of the "South Trap Range 

 east of Lake Gogebic in Michigan shows that both the lava flows, and 

 the eastern sandstone dip at a low angle, are one formation, and are as 

 conformable as eruptions of lava can be with a contemporaneous sedi- 

 mentary deposit. (Am. Journ. Sci., Nov., 1891). Cenozoic. 



—A new species of Moa from New Zealand is announced by Mr. 

 Lydekker, Pachyornis rothchildi. The speciesjs founded on the light 

 femur and the two tibio-tarsi and tarso-metatarsi figured and described 



in the Proceeds. London Zool. Soc, Nov., 1891. The bird-bones 



collected by Major Forsyth from the Plistocene beds of Corsica and 

 Sardinia have been referred by Mr. Lydekker to the following families: 

 Stringes, Aceiptres, Picaria, Passeres, Columbce Galling and Tur- 

 binates. (Proceeds. Zool. Soc, London, 1891., P-^ 67 )— JJ^*^

facts which warrant the conclu 



glaciation extended further southward than the hitherto accepted 

 terminal moraine. The character of this extra-moramic drift indicates 

 that it is probably the equivalent of the oldest glacial drift of the 

 interior. (Bull. Geol. Soc, Am., 1892, p. 173).
