New Species of Sponges. eg 
slender root spicules scattered on one of the slabs. On an- 
other specimen are large and strong forking spicules, the 
principal ray being about 1.5 centimetre in length, with a 
bulb or expansion at base, giving off two or more shorter 
and stout rays. They are quite different from any of the 
forms found at Metis. 
These specimens are from beds referred to the Levis or 
Sillery formation, and are therefore approximately of the 
same age with those at Metis. They indicate the wide dis- 
tribution of Hexactinellid silicious sponges in rocks of this 
period, and hold out the prospect of the discovery of addi- 
tional species. 
Mr. Ami also showed me a new sponge recently dis- 
covered by him in the Utica Shale at Ottawa. It consists 
of radiating groups of long slender simple spicules in a 
pyritized state. He hopes to make further collections from 
the same bed before describing these interesting forms, 
which resemble the spicules of the Pleistocene Tethea 
Logani,so common in the Leda clay of the St. Lawrence, 
but which may possibly be root spicules of a Hexactinallid 
sponge, as there are obscure cruciform spicules on the same 
slab. 
NOTES ON SPONGES FROM THE QUEBEC GROUP AT 
MéTIS, AND FROM THE UTICA SHALE. 
By Gxnorcp JpNNinNGs Hinpp, Pxu.D.! 
Through the kindness of Sir J. W. Dawson, F.R.S., I 
have had the opportunity of studying a series of specimens 
of the fossil sponges lately discovered in the Quebec group 
at Little Métis by Dr. Harrington, and also of an example 
of Oyathophycus reticulatus, Walcott, from the Utica shale 
formation. The Metis specimens are specially interest- 
' These Notes, kindly communicated by Dr. Hinde, arrived after 
the previous paper was in type; and are added without change.
