Tulameeii rivers. A close comparison with Dawson's U. pusillus from the Tulameen river 

 leads to the belief that the two are identical. 



In Lambe's collection from the Horsefly river in 1906 there were a few specimens 

 of a very small fruit, evidently that of an elm. Comparison with fruits figured by Heer shows 

 that there can be no possible relation to [7. speciosa, Newb., and that it is much smaller than 

 any of the fruits illustrated by Heer. It answers to the following description : — 



Wing broadly elliptical, 3.75 x 3 mm, incomplete; marked by numerous radiating 

 veins. Fruit ovate, acuminate, 1 mm broad, 1.75 mm long. It has the striation of U. speciosa 

 but is far too small to be it. (Fig. 33). 



Fig. 33. Ulmus minuta, Goepp. 

 A fruit from the Horsefly River, x 5. 



It seems probable that this may be the fruit of U. minuta, and it is .so referred for the 

 present. 



Ulmus proto-americana, Penh.

In material from the Kettle river, collected by Dr. Daly in 1 905, there were specimens 

 of wood which, from their somewhat close resemblance to U. americana, have been designated 

 as U. proto-americana. It is quite possible that either this or the next may be the wood 



of U. speciosa. 



Ulmus proto-racemosa, Penh. 



Bib : Trans. R.S.C., XIII, 1907, iv. 



This wood was associated with U. proto-americana in the deposits of the Kettle river. It 

 bears a very close resemblance to the existing U. racemosa. 



Ulmus speciosa, Newb. 



Bib: Proc. U.S. ITat. Mus., V., 1882, 507: Lat. Ex. Fl., XXXV, 80, pi. XLV, f. 2-8: Cret. 

 and Tert. Fl. VIII, 249, pi. LIV, fl. 10. 



Ulmus speciosa was first described by Newberry who recognized its close relation to 

 V. americana which he says it is in all its essential characters, though he preferred to recog- 

 nize it as the specific type. Knowlton, however, in dealing with material from the John 

 Day basin, considered that there was too great variation in size for all of them to be included 

 under the same species, and he therefore separates the smaller under the name of U.newberryi. 

 U.speciosa has been recognized in the Miocene of the John Day basin and Bridge creek, 

 Oregon, and in Canada it appears in the Tertiary beds of Coal gully, Quilchena and the 

 Horsefly river.
