Squalus squatina and Saccopharynx flaggelium. 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 is round, cylindrical, scaleless ; dorsal, 
anal and caudal fins united. Belongs to the order Cartila- 
gine, A particular anatomical description of this interesting 
gimal is much wanted.

Mileporites, with drawings and specimens. These are 
fowwd in a bank of alluvial sand, resting immediately on the 
prifitive rock of the Island. Dr. T. described two species | 
anqfour varieties of ramose millepores. Most of the speci- 
me's found belong to these species. ‘The division ramose 
he 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- 
-iains 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. 
Mr. N. Paulding read a memoir upon marine fossil 
shells, found in great abundance in every part of Prince
