Particular attention is called to the value of the oil of cassia, which has a refractive index of 1.60160 and clears from 80 per cent, alcohol. It is a most excellent reagent according to all experience in the laboratory, and in addition to its other good qualities it dries hard enough to make permanent mounts. On Some Turtle Remains from the Ft. Pierre. Contributions from the Paleontological Laboratory, No. 37. BY GEORGE WAGNER. Among the material collected this summer (1898) by the University Geological Expedition are some remains of turtles, from the Ft. Pierre. Though fragmentary, they are worthy of study; firstly, because they seem to be the first material of this nature collected from this horizon in Kansas, and almost the first from any locality; and secondly, because of their remarkable relation to the turtles described from the underlying Niobrara. Toacochelys latiremis Cope. A specimen consisting chiefly of the back part of the skull and a part of the upper jaw must evidently be referred to this species. The material (Kas. Univ. Museum, No. 1221) is in the poor state of preservation so common with Ft. Pierre fossils; it shows, however, fairly well most of the quadrate, the basisphenoid, and parts of the pterygoid, maxillary, basi and supra-occipital, and parietal. The sutures are indistinct except between the quadrate and pterygoid. (See fig. 1.)

Nos. 1214 and 1215), I fail to find any difference in specific characters; even in size they are nearly identical. A differenc.<
