A. M. Seely (Amer. Jour. Sci., July) describes three 
new species of sponges of the genus Strophochetus, and notes 
the distribution of the genus through the Middle Chazy.——?Pro- 
fessor N. S. Shaler contributes to the same issue an account of 
the geology of Cobscook Bay district, Maine. The uppermost 
beds of the series contain fossils which he refers to the Devonian, 
possibly to the Ohio shale. Below these are beds which seem to 
belong to the Niagara and Clinton horizons, while the most 
numerous list of fossils seems to be of Lower Helderberg horizon. 
The series is less rich in organic forms than that of the St. Law- 
rence or of Central New York. The land area of this fiord region 
'S principally occupied by intrusive volcanic rocks.

——Dr. Otto Meyer contributes to the Amer. Jour. Sci., July, 
1886, some observations on the Tertiary and Grand Gulf strata of 
Mississippi. His conclusions are (1) that in no place can Grand 
ulf strata be seen in superposition over the marine Tertiary ; (2) 
that there are two places where strata undistinguishable from 
Grand Gulf can be seen overlaid by marine Tertiary; (3) that the 
Grand Gulf formation is,mainly not marine; (4) that a thick and 
Post-tertiary.—M. A. Gaudry recently exhibited to the Paris 
Academy of Sciences a reindeer's antler pierced with a large hole, 
and covered with well-executed carvings. One face shows two 
Seals, a fish (salmon or trout) and three twigs of plants. One of 
me Seals seems to be Z. vitulina, On the other face are two eel- 
like slender animal figures, three indeterminable animals (alike)
