PALEONTOLOGY. 387 



in the cities of Colorado along the Front Range. In Texas many 

 interesting specimens were studied. At Baylor University was found 

 the skull of Nothrotherium, an edentate genus, found originally in 

 South America, but known to occur also in caves and asphalt pits in 

 California. At College Station, Texas, the large collection of Pleisto- 

 cene vertebrates made by Dr. Mark Francis was studied; also the 

 collection at the State University of Texas, at Austin, which contains 

 many types of Cope's species. Valuable materials were seen at two 

 institutions in New Orleans. The vertebrate collection of the Florida 

 Geological Survey has been turned over to the writer for study. An 

 unexpected amount of vertebrate remains was found in the Museum 

 at Charleston, South Carolina, and the use of this has been secured. 

 Evidence was obtained of the existence there, probably during some 

 cold stage of the Pleistocene, of a moose closely related to the Canadian 

 species. Incidentally, it was found that during the Miocene the three- 

 toed horse Parahippus, not hitherto found east of the Great Plains, lived 

 along the Atlantic Coast. As a result of the trip several new species 

 have come to light and our knowledge of the distribution of others has 

 been increased. 



The months since January have been spent in studying materials 

 obtained on the trip mentioned and other materials sent from ^'^arious 

 parts of the country. 



Wieland, G. R., Yale University, New Haven, Connecticut. Continuation 

 of investigations on fossil cycads. (For previous reports see Year Books 

 Nos. 2-4, 6-9, 11-13.) 



The text of the memoir on the Mexican Liassic Flora, prepared 

 several years ago, has been printed by the Mexican Geological Sui-vey 

 and the plates also are ready; but owing to conditions in Mexico this 

 work has thus far failed of binding and distribution. If finally neces- 

 sary, an adequately illustrated abstract will be prepared for publica- 

 tion in English, the memoir being in Spanish. 



Considerable progress has been made in studies of the anatomy of 

 Cycadeoidean wood. These studies are limited to the best sihcified 

 trunks in order to clearly show that, aside from specialized features, 

 the Cycadeoids have essentially the same wood structure as that of the 

 more tree-like gymnosperms. In particular, the Cycadeoidea dacotensis 

 (figured on plate vi, phot. 8, of Vol. I, American Fossil Cycads, and 

 considered the finest stem among 800 Yale specimens) is being sawed 

 through longitudinally and transversely with the object of cutting the 

 thin sections from definitely located serial positions. The wedges cut 

 from a few other less conspicuous but equally well-conserved American 

 and foreign trunks are likewise receiving study. The urgently required 

 field work in the mid-Mesozoic terranes already planned can not be 

 begun before the new year.
