and a inaximuin widtli of o nun. Tlie niidnerve is strong and the texture 

 of the leaves very thick and leather-like. They are often transversely 

 wrinkled, no doubt from shrinkage. 



PI. WW. l"ig. 10 represents a gi"oup of leaves, one of them .showing 

 traces of a sheath at its base. These are shown slightly enlarged in Fig. 

 11. Figs. 12 and 13 give portions of two medium-sized leaves. Figs. 14 

 and 15 represent the longest leaf seen, it not being entire. Figs. 16 and 

 17 denote the witlest fragment found. 



The leaves are most abundant at locality No. 19, and they are not 

 rare at locality No. 7. 



Genus CYCLOPITYS Schmalliausen." 



Cyclopitys oregoxensis Fontaine ii. sp. 



PL XXXVI. Fig. 1. -2. 



A single specimen, and its reverse, of a whorl of Taxus-like leaves was 

 obtained at locality Xo. 7. Schmalhausen has established the genus 

 Cyclopitys* for the plants that have an affinity with Sciadopitys. The 

 Oregon fossil resembles those that he calls Cyclojntys Nordenskioldi,'' but 

 the leaves are broader and not so rigid, and are probably longer. The 

 Oregon fossil shows only one whorl, composed of 18 leaves, some of the 

 leaves being evidently missing from the whorl. The leaves are attached 

 by thin narrow^ed bases. The stem is not seen. The leaves are rather 

 thin in texture. Their precise mode of attachment can not be made out, 

 as their bases are crowded and distorted. They seem to be attached by 

 narrow^ed bases and not by petioles. Only the basal portions of the 

 leaves are preserved. They seem to have been of about the size of those 

 of Taxites zamioides. There is a midnerve in each leaf that is rather 

 slender. This nerve sometimes appears as a slender cord-like nerve with 

 a depressed line on each side, and sometimes as two closely placed nerves. 

 This difference seems due to the fact that in the one case the lower surface 

 of the leaf made the imprint and in the other it was made by the upper 

 face. Schmalhausen'' regards Heer's Pinus Nordenskioldi as a Cyclopitys. 

 This mav be the case with some of the forms that Heer has united in that 



a It seems probable that this genus belongs to the familj' Taxacese instcud of the family Pinacese. — L. F. W.
