.since obtained, nvv. ])efore mo. They not only agree among" themselves

 There can be no reasona1)le doubt as to their identity. 



A num1)er of sp(>cim(Mis have ))een found in the Mascall beds at Van 

 Horn's ranch and \ icinity that must also ])e referred to Grewia cre- 

 nata. Th(^ single exam[)le referred by Lesqnereux to Pallurits 

 colomhi proba))ly belongs here, although it is very nuich like certain 

 forms of PopnJuH Z'^^/^/^^/'/f/ from the Auriferous gravels of California. 

 The leaves, three in lunnber, from the Mascall beds are a little nar- 

 rower than tliose from Bridge Creek, and are somewhat more deeply 

 cordate or auriculate at base, but the differences are not sufficient to 

 warrant separating them. 



Locality. — Bridge Creek, Oregon. Collected by Rev. Thomas 

 Condon (U. S. Nat. Mus., Nos. 7077, 7078, 7079) and"Maj. Charles E. 

 Bendire (U. S. Nat. Mus., No. 9532). Mascall beds. Van Horn's ranch 

 and vicinity. Collected l)y Major Bendire (U. S. Nat. Mus., No. 2542) 

 and by Knowlton and Merriam July, 1901 (U. S. Nat. Mus., Nos.

Grewia auriculata Lesq. 



Gkewia auriculata Les(i., Cret. and Tert. FL, p. 252, PL LV, fig. 1, 1883. 



This species appears to rest on the single example tigured as the 

 type. None of the recent collections contain it, although there are a 

 number of specimens of G. crenata. 



The type of G. auriculata should be in the University of California, 

 but it can not now be found. If it has been correctly tigured it seems 

 to be very different from the other leaves of Grewia found in the same 

 beds, although it ma}- be only an alT>normal form of that species.
