calcareous rocks enclosed in a magma heated to fusion—a true meta- 
morphism. (Revue Scientifique Fevier, 1895). 
Mr. Walcott notes the occurrence of Olenellus in the limestone of 
the Green Pond mountain series of northern New Jersey. He con- 
siders the discovery a positive addition to the data for working out the 
stratigraphy of the series. Occurring as it does, in a limestone that 
merges above and below inte beds of conglomerate that are essentially 
of the Green Pond mountain type, it proves that the conditions under 
which this characteristic formation was formed, began in lower Cam- 
brian time. (Am. Journ. Se., 1894). 
Mrsozor1c.—It is well known that Triassic rocks have yielded large 
quantities of good coal in Virginia and North Carolina, but it is only 
within the last year that coal in paying quantities has been found in 
Pennsylvania Trias. Early in 1894 a vein of anthracite coal of fine 
quality, twenty-six inches thick, was discovered at Arcola Station, on 
the Perkiomen railroad, about twenty-five miles from Philadelphia. 
The rock in which it occurs is red sandstone of Triassic age. 
Other instances of the occurrence of coal in Montgomery Co. re- 
ported by Mr. Oscar Franklin as follows: In the new red sandstone at 
Norristown ; at Gwynedd in the same formation, and at Lower Provi- 
dence, Lansdale and Hatboro. A systematic search of the slates ‘un- 
derlying the sandstone in Montgomery Co. would, perhaps, disclose beds 
of workable coal in more than one locality. (Journ. Franklin Inst., 
1894). 
In Colorado College Studies for 1894, Mr. F. W. Cragin notes 2 new 
reptiles and 3 new fishes from the Neocomian of Kansas. They are 
described under the following names: Plesiosaurus mudgei represented 
by a femur, humerus and dorsal vertebræ. Plesiochelys belviderensis 
represented by several costal bones, neural bone and a vertebra. Me- 
sodon abrasus represented by vomerine teeth. Lamna quinquelateralis 
and Hybodus clarkensis based respectively on a vertebra and on a fin 
spine. Figures accompany the descriptions. 
Crenozoic.—After reviewing the evidence for changes of elevation 
of the Atlantic coast of North America, Mr. N.S. Shaler states that 
since the beginning of the Glacial epoch the eastern shore of North 
America from the Rio Grande to Greenland has, though with many 
minor oscillations, been prevailingly lowered. The fauna of the Car- 
ibbean District points to a recent subsidence of that region, including 
the peninsula of Florida. The flooding of the Amazon and La Plata
