They are quite similar to those figured by Heer in the fossil flora of Siberia. Heer refers them in the text to Piuus, and in the legend of one of his plates to Cyclopitus, while he seems to belieA'e that certain taxus-like fruits may be refer- able to this plant. S'-bcnck (Fossil Botany) refers them to Cyclopitus and seems to believe that this genus is int iiediate between Abietineoc and Taxineu\ Fontaine refers very- similar leaves to the genus Cephalotaxopsis. Cyclopitus is described as having verticel- late leaves, but there is no evidence of our species haviug had its leaves arranged in that way. Schenck refers to the modern Scyadopitys as possibly allied. The leaves of this species have evidently been deciduous and drifted over the muddy bottom in immense quantities. With them are sometimes found small ovate flattened nutlets ; but whether connected with the lea^-es is uncertain. It is to be hoped that the excavations for coal will disclose more perfect specimens. Pinus anlliracitic/is {a. n.) (Fig. 10.) Fid. 10.—I' aiillirwiliiii!': A single winged seed referable to Pinus was found in the beds holding the above species and raises the question of its possible alliance to that genus. The seed is rounded, about 2 mm. in diameter. The wing expands slightly toward the distal end, and with the seed is about 1 cm. long, but its extremity is slightly broken, though it seems to be obliquely truncate. The wing is smooth with a few obscure veins. Cephalotaxopsis (Sp.) Very imperfect fragments are found at Anthracite, possibly referable to this genus, which belongs to the Lower Cretace
