ocephala ; of Cyprinodonts, Trichophanes foliarum and T. Copei; of 
Catostomidae, Amyzon pandatum, A. commune, and A. fusiforme ; and 
of Siluridae, Khineastes pectinatus. All the species have been described 
by. Cope* excepting TY. Copei, which was published by Osborn, Scott, 
and Speir. 
Several bird’s feathers have been found in these beds, and a single 
tolerably perfect Passerine bird, with bones and feathers, has been de- 
scribed by Mr. J. A. Allen under the name of Palaeospiza bella, and 
admirably illustrated by Blake. No other figure of a Florissant animal 
has yet been published. Besides these, Professor Cope has just de- 
scribed a plover, Charedinus sheppardianus, and writes that a finch is 
also found in these beds. 
The plants, although less abundant than the insects, are exceedingly 
numerous, several thousand specimens having already passed through 
the hands of Mr. Leo Lesquereux. Of these he has published 37 species 
in his Tertiary Flora,t about two-fifths of which are considered iden- 
tical with forms from the European Tertiaries. Of other specimens 
which he received after the publication of that volume, he has already 
given a cursory account in the annual report of Dr. Hayden’s survey for 
1876. He has also mentioned others in his review of Saporta’s Monde - 
des Plantes, and still others in letters. From these sources and from 
memoranda communicated by him, based on the plates of the Florissant 
species prepared for the eighth volume of Hayden’s Report, the follow- 
ing review is drawn: 
Among the exogenous plants the following polypetalous families are 
represented: Some flowers with long stamens are referred doubtfully to 
the genus Bombax, one of the Malvaceae. Of Tiliaceae, a species of Tilia 
has been found; of Rutaceae, one species of Ailanthus. Of Anacardiaceae, 
three species of Rhus are described under the names Hvansi, rosae- 
Jfolia, and Haydeni, and three or four others mentioned. Of Juglandeae 
one species, and one of Zanthoxyleae. Of Rhamnaceae, Paliurus Floris- 
santi is the only species. A few leaves of Celastrus represent the Celas- 
traceae. The Sapindaceae are very abundant, three genera occurring; 
leaves of Staphylea acuminata, numerous specimens of Sapindus stellar- 
iacfolius and S. angustifolius, as well as of two or three other species 
of the same genus, and two species of Acer, represented by flowers, 
leaves, and fruit. The flora has a large number of Leguminosae, of the 
genera Robinia, Colutea, and Cassia, besides Acacia septentrionalis and 
Mimosites lineartfolius, described in the report mentioned. The Rosa- 
ceae show a Prunus, leaves of Rosa, and species of Spiraea, with very 
finely preserved leaves of an Amelanchier, scarcely distinguishable from 
some of the varieties of the living species. Liquidambar europaeum Al. 
Br. represents the Hamamelidae; numerous leaves of Weinmannia, the 
Corniculeae; and, finally, there is a single species of Araliaceae, closely 
allied to Aralia multifida Sap. Excepting the Liquidambar none of the 
Polypetalae have been shown to be identical with European forms. 
Among the monopetalous plants the Ericaceae are represented by 
Vaccinium reticulatum Al. Br., together with one or two species of Andro- 
meda. Two species of [lex,one described as J. subdenticulata, represent 
the Aquifoliaceae; one of Diospyros, the Ebenaceae; a species of Catalpa, 
the Bignonaceae. Oleaceae have a flowering branch of Olea’and four 
species of Fraxinus, one referred to Heer’s F’. praedicta and another de- 
scribed as new under the name of F. Brownelli. 
The apetalous angiosperms show a great variety of forms at Floris-
