" On the Discovery of Turrilepas in the Utica Formation (Ordi- 

 vician) of Ottawa, Canada.'' By Henry Woodward, LL.D,, 

 F.H.S., F.G.S. Geol. Mag. No. 300, Dec. Ill, Vol. VI, p. 271. 



In this contribution to the palaeontology of the rocks about 

 Ottawa, Dr. Woodward, Keeper of the British Museum, «fec., &;c., has- 

 described a very interesting and beautiful little species of cirripede 

 found by Mr. Ami, of the Geological Sui'vey, in the " Siphonotretar 

 band " or zone along the right bank of the Rideau river at the head 

 of the Rifle Range Rapids. This species is described by Dr. Woodwai-d 

 as Turrilepas Canadensis, and the description is accompanied by an 

 enlarged figure of the same. A note by Mr. Ami on the exact geologi- 

 cal position of this ciri-ipede is included in Dr. Woodward's paper, and 

 the species referred to the Lower Utica formation. J. F.
