A remarkably well preserved and nearly perfect specimen of P. Skide- 

 gatensis, from the Queen Charlotte Islands, and probably from the Lower 

 Shales at Skidegate Inlet, was presented to the Museum of the Survey in 

 1893, by the Curator of the Provincial Museum at Victoria, B.C. It 

 measures nearly eight inches in its maximum diameter, and shows the 

 greater part of five volutions. A large fragment, consisting of a cast of 

 the interior of the body chamber, about eight inches in length, of a speci- 

 men that is probably referable to P. Skidegatensis, was collected by Mr. 

 Robertson, in 1896, at a locality between "Yukon Lake and the head of 

 Rennell Sound, and lent to the writer by Dr. Newcombe. 



The septation of this shell is still unknown, and Dr. Kossmat, as 

 already stated, thinks that it may prove to be an Olcostephanus of the 

 type of the 0. Zirkeli of Felix and Lenk*, from the Cretaceous rocks of 

 Mexico.

This peculiarly sculptured Ammonite was described and figured from a 

 fragmentary specimen collected on the north shore of Cumshewa Inlet by 

 Dr. G. M. Dawson in 1878. Of late years five other specimens have 

 been obtained at this locality. One of these is a small but comparatively 

 perfect specimen, not quite two inches in its maximum diameter, collected
