One of the two type specimens of Myrica scottii ^ is preserved in 

 the United States National Museum (No. 1,660), and also one of the 

 two specimens illustrated under the name of Myrica polyinorpJia 

 Schimper,^ and as there seems to be no essential difference between 

 them they have been combined as above indicated. The teeth in 

 the original M. scottii are perhaps a little longer and sharper than is 

 shown in the figures of 21. polymorpha, but the latter are not quite 

 correctly shown in Lesquereux 's figures, being as sharp in many cases 

 as in the other. This species may be distinguished by the long, very 

 slender shape and the conspicuously sharp teeth. 



The Lacoe collection contains a single small narrow leaf (U.S.N. 

 M., 50,239) that was identified by Lesquereux as Myrica zachari- 

 ensis Saporta, but it clearly belongs with M. scottii. It is wholly 

 unlike the Florissant leaf referred to M. zacJiariensis by Lesquereux.^ 



I have also referred here two of the leaves figured by Lesquereux 

 under the name of Myrica acuminata Unger, namely figures 1 and 4 

 of his plate 17. These are Nos. 143 and 145a in the United States 

 National Museum collections. The other two figures are referred to 

 M. drymeja. The two leaves here referred to M, scottii have been 

 refigured (pi. 21, figs. 3, 4). 



MYRICA COPEANA Lesquerenx. 



Myrica copeana Lesquereux, Ann. Rept. U. S. Geol. and Geogr. Surv. Terr. 

 1873 [1874], p. 411; Rept. U. S. Geol. Surv. Terr., vol. 7 (Tert. FL), 1878^ 

 p. 131, pi. 17, fig. 5.— Cockerell, Bull. Amer. Mus. Nat, Hist., vol. 24* 

 1908, p. 81. 



Type.—C2it. No. 147, U.S.N.M. 



This, as Lesquereux stated, is a fine, large, well-characterized spe- 

 cies, described originally from a single specimen. It is not contained 

 in any of the collections studied in the United States National Mu- 

 seum, but CockereU mentions its occurrence at his station 9, so the 

 type-specimen evidently is not unique. It must, however, be con- 

 sidered as a rare species.
