Squalus squatina and Saccopharynx flaggellum. All these 
are found in our waters, and form a valuable addition to our 
icthyological catalogue. Of these the S. flagellum is the 
most interesting. This species is six feet in length, the 
body and head being but fourteen inches. In the shape 
and structure of the body it differed so much from every 
fish hitherto known, that some doubt was at first entertained 
whether it actually did belong to that class. This however 
was fully established by the learned president. By means 
ofa particular structure, not easily understood except from 
actual inspection, the animal is able to dilate his mouth to 
an astonishing extent; from this and the whip-like appear- 
ance of his tail, he has derived his generic and specific 
names. The body i is round, cylindrical, scaleless; dorsal, 
anal and caudal fins united. Belongs to the order Cartila- 
gine. A particular anatomical description of this i interesting 
animal is much wanted. 
Dr. Townsend read a memoir on the organic remains at 
Corlaer’s Hook, in the environs of New-York. Part 1s 
Milleporites, with drawings and specimens. “These are 
found in a bank of alluvial sand, resting immediately on the 
primitive rock of the Island. Dr. 'T. described two species 
and four varieties of ramose millepores. Most of the speci- 
mens found belong to these species. The division ramose 
found it necessary to establish, although it approaches 
the millepora truncata of Ellis. Of reticulated millepores he 
describes one species. The great abundance of these re-_ 
mains serves to refute the opinion of Parkinson, (Vol. 2. p. 
71.) that there are few millepores in a fossil state. The sub- 
stance of these specimens is alumino-silicious. 
N. Paulding read a memoir upon marine fossil 
Arlls, found in great abundance in every part of Prince 
eorge’s county, A ae. and presented to the society by 
1. W. Philip, U.S. A. They belong to the genus pectun- 
culus, turritelea, arca, murex and teredo of authors.
