was the case with the fossil. Tins is apparently the plant 

 described by Prof. E. Forbes (Jour. Geo. See. Lon. vol. vii, 

 p. 103), under the name of Filicih s (?) />< bridicus^ and obtained 

 by the Duke of Argyle, from the Island of Mull.

Leaf very large, 8-10 feet diameter with 50 to 80 folds; petiole 

 long, l£ to 2 inches wide, flat above, without a central keel above 

 or below, unarmed; nerves numerous and fine, about «"><) in each 

 fold, six principal ones on each side of the midrib, with il 

 intermediate ones between each pair, the middle one being strong' 

 est. 



In general character the leaves of this palm have a strong 

 resemblance to those of Sabal mcyor, Ung. sp. (Chloria Trot. 

 S. 42, Taf. xiv. fig. 2; Flor. Tert,, Ilelvet 1, S. 88, Taf. kxxv. 

 xxxvi. figs. 1, 2); the size of the leaf, the number of folds, and 

 the character of the nervation being approximately the same, 

 but in our plant the average size of the leaf is greater, the num- 

 ber of folds larger, and the petiole is without a keel. The form 

 of the spindle, or terminal point of the petiole on the under side 

 of the leaf, as exhibited in the numerous specimens collected 

 by Dr. Hayden, seem to be shorter (more abruptly acumi- 

 nated by a concave lateral excavation) than in the exam] 

 of S. major which have been figured or described. This char- 

 acter has little value, however, as it varies considerably in the 

 different leaves. This species was first described from a 

 of specimens collected near Bellingham Bay, W. T., b ' 

 Gibbs, Esq., Geologist to the U. S. X. W. Boundary Comn 

 sion, of which the figures are not yet published. They Bho¥ 

 only the upper side of the leaf, leaving the form of the point of 

 the petiole on the under side to be conjectured. Thia want 

 has been fully supplied by the collections mad.- by Dr. Hayd 

 when connected with the expedition under Capt. \V. I. Ray.
