304 RECORD OF SCIENCE FOR 18«7 AND 1888. 



James Hall (96) notes the discovery of au elk [Elaphus Canadensis) 

 [sic\ in the town of Farmington, Ontario County, New York. The title 

 is as above, but it does not appear whether the author intends to in- 

 dicate the species found to be the red deer {Cervus elaphus, Linn.), or 

 the wapiti {Cervus Canadensis^ Erxl.), or the true moose. 



Joseph Leidy (147) announces the discovery of a new species oi Hip- 

 potherium, which is described and figured, p. 310, under the name Iliji- 

 potherinm plicatile. 



O. C. Marsh (165) briefly describes a new fossil Sirenian from (Cali- 

 fornia, proposing the name Desmostylus hesperus (gen. et sp. nov.), pp. 

 95,96, figs, 1, 2, 3, Tertiary, Alameda County, California. The same 

 author (161) describes several new fossil mammals as follows : 



Bison alticorilis (up. nov.), p. 323, f. 1, 2, Denver group, near Denver, Colorado. 



Aceratherium nciititm (sp. nov.), p. 325, f. 3, 4, Pliocene, Phillii».s County, Kan- 

 sas. 



Bronto2>ii robitstui:! (gen. et sp. nov.), p. 326, f. 5, 6, Lower Miocene, near White 

 River, Nebraska. 



Brontops dispar (sp. nov.), p. 328, f. 7, 8, Lower Miocene, Dakota. 



Menops rarians (gen. et sp. nov.), p. 328, f. 9, 10, Lower Miocene, Dakota. 



Titanops curlus (gen. et sp. nov.), p. 330, f. 11, Lower Miocene, Colorado. 



Titanopts elatm (sp. nov.), p. 330, f. 12, Miocene, Dakota. 



Allops seroUntis (gen. et sp. nov.), p. 331, Miocene, Dakota. 



Mr. W J McGee (176) notes the discovery of Ovibos cavifrom from the 

 Loess of Iowa. 



W. B. Scott and H. F. Osborne (230) give a preliminary account of 

 the fossil mammals of the White River formation in the Museum of Com- 

 parative Zoology collected by Samuel Garman in Nebraska and Da- 

 kota. The following new species and genera are described : 



nyoilieriiim Americmuim (sp. nov.), p. 155, no figure. 

 Miiiodus ticUoceras (sp. nov.), p. 159, sketch 2 of figs. 5, G. 

 Minodns dolivhoceras {sp. nov.), p. 160, sketch 3 of figs. 5, 6. 

 Minodus plaiijceras (sp. uov.),p. 160, fig. of horns, f. 4. 

 Metamynodon planifrons (sp. nov.), pp. 165-109, f. 7, 8, 9. 

 Hyracodon major (sp. nov.), p. 179, no figures. 

 Eiiracodon planictp^ (sp. nov.), p. 170, no figures. 



The genus Menodus, Pomel, is defined p. 157, and the following gen 

 era are recorded as synonyms, viz, Titanotherium, Leidy, Megacer 

 ops, Leidy, Brontotherium, Marsh, ('? Symhorodon Cope), Diconodon 

 Marsh. Restorations are given on plate i of Eoploplioneus prinmvns 

 Leidy, one-fourth natural size, and on plate ii of Menodus Proutii, Leidy 

 one-sixteenth natural size. Amynodon, Marsh, 1877, is defined on p. 164 

 and the author's genus Orthocynodon (Scott and Osborne, 1883) is con 

 sidered to be a probable synonym. The new genus Metamynodon is 

 named and described, p. 165, founded upon the new species M. plani 

 frons, pp. 165-169, f. 7, 8, 9, and the genus is referred to the Amynodon- 

 tidiB.
