114 TRANSACTIONS OF THE [JAN. 30, 
Juancito, Honduras, among other geological specimens, a small 
fragment of metamorphosed shale full of the impressions of the 
fronds of Cycads. As no Messozoic fossils had, so far as I knew, 
been brought from this region before, the discovery interested 
me much and I have since made earnest efforts to obtain other 
specimens from the same locality. Mr. Rolker kindly seconded 
these efforts and wrote to Mr. T. H. Leggett, E. M., also a 
graduate of the School of Mines, who is located at San Juancito 
in superintendence of a silver mine, giving him all the informa- 
tion he possessed in regard to the locality of the fossils. Mr. 
Leggett took up the search with enthusiasm, but until recently 
without success. A few weeks since I received a letter from him 
announcing the rediscovery of the plant beds and the shipment 
to me of a small box of fossils. This arrived last week and al- 
though the specimens are not numerous and the rock contain- 
ing them is much weathered, they have furnished me some addi- 
tional light upon the deposit which contains them. ‘The plant 
remains are very numerous, closely packed together and the state 
of preservation leaves much to be desired, but they are signifi- 
cant and interesting and enable me to fix with a good degree of 
certainty their geological horizon. ‘The species represented are 
briefly as follows. 
1. A new species of Zamites, allied to Z. occidentalis, a fossil 
plant obtained by Mr. Remond, from the Upper Triassic coal- 
bearing rockson the Yaki river, in Sonora, and described by me 
in the report of the San Juan Expedition, p. 152, Pl. V. This 
is much the most abundant fossil in the collection: the stipe 
of the frond is chaffy and the pinnules are set alternately on its 
upper face, and attached by their entire bases, which meet and 
completely cover the stipe. ‘The pinnules are linear, from one 
and a half to two inches long, rounded at the upper extremities 
and traversed by numerous fine parallel nerves. The specimens 
of Z. occidentalis figured in the report mentioned above are all 
from the lower portion of the frond, and the pinnules are repre- 
sented as attached to the sides of the stipe. Higher up their 
bases are brought nearer together and perhaps finally meet. 
Among all the specimens sent by Mr. Leggett none show well 
the lower part of the frond, and the characters given above are 
such as belong only to the upper portion. For this plant I pro- 
pose the name of Zamites Rolkeri, thus connecting with it the 
name of its discoverer. 
2. A species of Zamites similar to the preceding in general as- 
pect, but having much narrower fronds and shorter and broader 
pinnules, which I name Z. Leggetti, in honor of Mr. 'T. H. Leg- 
gett who was the first to obtain it. It has also a somewhat dif- 
ferent nervation ; in Z. Rolkeri the nerves are all simple, fine,
