DESCRIPTION OF SPECIES— CELASTRE^. 269 



ondary nerves curving at a distance from the borders, and forming a double 

 series of bows by anastomosis of the nervilles. The characters of the nerva- 

 tion are the same as in Celastrus cassinefolius, Ung., figured by Ileer (FI. 

 Tert. Helv., iii, pi. cxxi, figs. 24-26), but our leaf is twice as large as those 

 represented by the European authors. I have been a long lime in doubt, 

 and am still uncertain, of the true relation of this and the following species. 

 Habitat. — Golden, Colorado {Rev. A. Lakes). 



Cclastrinites Isevigatiis, sp. nov. 

 Plato XVII, Figs. IC, 16 a. 

 Myrica amhigua, Lesqx., Auuual Report, 1371, p. 297. 



Leaves bard, subcoriaceous, with a smootb or polished surface, apparently long, linear or oblong, 

 with borders distantly denticulate ; secondary nerves in right angle, branching from the middle, each 

 with one or two intermediate, parallel, tertiary veins. 



Nothing has been seen in relation to this species but the fi-agments 

 figured, which represent the lower part of somewhat large leaves. They 

 greatly resemble part of leaves of Banksia and Dryandroides, mostly now 

 considered as Myrica, like D. Banksiafolia, Ung., D. Icevigata, Sap., D. ligni- 

 tum, etc., as may be seen by the numerous figures representing these species 

 in Heer (Fi. Tert. Helv., ii, pi. xcix, figs. 4-16). The character of nervation 

 presents a notable difference; for, in this American form, the secondary veins 

 do not pass on to near the borders but anastomose in the middle of the lamina 

 by nervilles joining them to branchlets, either of the tertiary or of the upper 

 secondary nerves, and, by their subdivisions, they form along the borders a 

 double or triple range of festoons. This character indicates their relation 

 to the Celastre(B, and is marked indeed in some of the species of Celastrinites 

 described by Saporta in the Suzanne i'lora, especially in C. legitimus and C. 

 ■cenulosm, as represented in pi. xv, figs. 11, 12, and 13. I followed the opinion 

 of this celebrated paleontologist in referring these fragments, like the former, 

 to this genus. 



Habitat. — Six miles above Spring Canon, top of the hills, between 

 Fort Ellis and Bottler's Ranch, Montana {Dr. F. V. JIayden).

ILEX, Linn. 



In the records of the plants of the present epoch, we find about twenty- 

 five species of Ilex satisfactorily descril>ed, mostly referred to North and
