Some few of these are shown with Htlh' (hstortioii.'aiHl tliey resemble 

 those of Braclivphylhim; that is, they are thick and rhoml^ie in form, 

 with tlie greater (hniensions transverse to tlie axis of the cone. Most of 

 them, however, are in this trans\'erse cHrection so much elongated and 

 distorted that lliey appear as parallel i-aised lines. The mature cones 

 may he compared with the cone h. Marc (UKn/uni Brongn., as given l)v 

 Saporta in Paleontologie Francaise, Pluntes Jurassicjues, Vol. Ill, pi. 

 xxxix, fig. 2. They are, however, broader than that, which may l)e due 

 to the distortion transver.se to the axis of the cones. The cone scales 

 are larger than those of B. Moreauanum, and the species is probably 

 different. There are also, as stated, obscure bits of twigs, which appear 

 to belong to the same plant as that carrying the cones. The>- are mostly 

 decorticated, but a few .show vague traces of leaf scars similar to those 

 of Brachyphyllum. 



The apparent sti'obiles are small cylindrical fragments with chaffy 

 scales. They probably belong to the plant that shows the larger mature 

 cones. There are several small elliptical to globose cones that are much 

 smaller than the mature ones. They apparently have the same kind of 

 cone scales as the larger cones, l)ut smaller and thiimer. These mav be 

 immatin-e cones of the plant carrying the larger cones, the male strol)iles, 

 and the leafy twigs. 



Brachyphyllum is most developed in the Jurassic and Lower Creta- 

 ceous. If we may regard this plant as belonging to that genus, then, 

 so far as its evidence goes, the strata are Jurassic or Lower Cretaceous. 

 But as the generic place of the fossil can not be determined positively, 

 and the amount of material is so small, the age can not be certainly- fixed.

This specimen was obtained by Dr. A. C. Peale from the east slope 

 of the Bridger Range, north of Bridger Creek, Montana, and is labeled 

 by Doctor Peale as Jurassic. Professor Ward gives as the more exact 

 locality 4 miles northeast of Bozeman, Mont., on the right l)ank of 

 Bridger Creek. The fossil is a small bit of a twig 25 mm. long, with a
