22. DiooNiTEs KOKKALTs. S. X. (PI. TIL. Fiij. 3*7.) 



IVtioli' thick, lonn-itiidinally striata. Leaflets lii milliinetivs wide, pavallel-sided, dornr- 

 rent at hase on the petiole, loiiiritudinally striated with al)out 15 striiB. Ijtnigth of leaflets, 

 eeutimetres or more, terminations nnknown. 



This is a frairment of a leaf similar to that of Dimtiiiles ColiinihiiDiiiK from the Queen 

 Charlotte Islands, but diU'evinir in size and venation. Similar leaves have been found by 

 Fontaint' in the Ix)\ver Cretaceous of ^ irijinia, and in Europe they are considered to be 

 characteristic of the I.owcr Cretaceous. In America, however, Dioiin ediile still survives as a 

 representative of this type of cycads.

1. Neuropteris C.\stor. S. N. (Fie-. 14, 14a.) 



Pinnules at right angles to rhachis, closely set, oblong, al)ruptly pointed, attached by 

 whole ba.se. Midril> .stronu:. fading before reaching the point. Veins obscure, but apparently 

 at an acute angle to tlie niidril). Very ainindant at Beaver Harbour. 



Collected by Dr. Cr. :\I. Dawson. 



2. T.ENIOPTERIS PLUMOS.\, S. N. (Fig. 15.) 



Tiesembles closely T. Villiilii and T. Gibbsii of Newberry, but has the veins forming an 

 ani.'le of .">0^ with the midrib, which is very strong, giving oil" to the even margin strongly 

 marked parallel veins. Breadth 2 centimetres ; length and termination unknown. 



Collected by Dr. G. M. Dawson at Baynes' Sound. 



3. Nii>!.><ONiA L.\T.\, 8. N. (Figs. 15, bis. 15 a.) 



Frond at least (> centimetres broad. Pinnules about 1.2 centimetres in breadth, each 

 with about 30 parallel veins at angle of 50'' from the ril). Piiuue separated from eai'h other 

 by narrow acute lacunir. Midrib broad and channeled. Terminal i>iiina a little broader 

 than the lateral segments. 



Collected by Dr. G. M. Dawson at Baynes' Sound. 



4. Pteris (Oleandra) Gix)ssopteroide!<, S. N. (Fig. 16.) 



Pinna lanceolate, 2 centimetres wide, 8 or more long. Midrib strong, giving ofT 

 ascending curved twice-forking veins, which from their llexuous cliara< ter sometimes 

 appear netted. Margin of pinna apparently inilexed or thickened. liesembles Olmndra 

 iirrlini, Heer, from Greenland ; but has the veins at a more acute angle.

5. Sphenopteris elonoata, Newberry. (Figs. 17, 17 a.) Newberry, Boston Journal of 



Natural History, Vol. VII., No. 4. 



This species was described by Newberry, from si)ecimcns colleiled at Orcas Island, 

 on the Coast of Oregon. It is compared by him with N. Vrrhllii, Brngt. It is doul)(fully 

 refi-rred to Sphninplrris, but as the frucliiication is unknown, may be allowed to remain 

 there at present.
