The fossil fi'om Cui'iy County, ref:;ai-(led as probably a specimcai of 

 ('Idddlihlchis vdcccnxis, consists of a sin<!;le detacluMl pimiule. It ai^rees 

 exactly with some of th(~ pinnules of that fern. Of course^ a positive 

 identification can not be made with so small aji amount of material.

Two fragments of leaflets are found in the Curry County fossils that 

 seem to lielong to Ctoiis .sulcicaidis. They are detached and show 

 neither base nor tips, so that the true position of the fragments can not 

 be determined. C. sulcicaulis is an important fossil in tlae Buck Mountain 

 Jurassic strata. In these small fragments the texture and the slender 

 nerves agree well with those features in the Buck Mountain fossil. The 

 mode of anastomosis of the nerves in both is exactly the same. 



PI. XXXVIII, Fig. 7, gives the most complete fragment. Idie 

 nerves are so fine that they can be made out only with the help of a lens. 

 They are shown enlarged in Fig. 8.

On the rock specimens of the collection there are several strap- 

 shaped fragments of leaves that indicate the presence of a Ctenophyhum of 

 the type of C. densifolium'' of the Oroville flora. If it is a Ctenophyllum it 

 is probably a new species, but the material is too imperfect and too small 

 in amount to permit a full and accurate diagnosis to be given. The
