[WHITEAVES] VANCOUVER CRETACEOUS FOSSILS 131 
Sutural line as represented on plate 14, figure 2a, of the second part 
of the first volume of “ Mesozoic Fossils,” published by the Geological 
Survey of Canada. 
Sucia Islands, J. Richardson, 1874: one crushed specimen, with the 
sutural line well preserved, Northwest side of Hornby Island, W. Harvey, 
1893: two good specimens, one of them apparently free from distortion. 
All three, upon the whole, agree remarkably well with Jimbo’s descrip- 
tion and figures of 47, obstrictus, although in that species there are two 
transverse constrictions of the prolonged portion of the shell, as well as 
one on the reflected portion, and the lobes and saddles of its sutural line 
are perhaps not quite so numerously incised as those of the specimen 
from the Sucia Islands.

Pachydiscus Ootacodensis, Kossmat. 1894. Jahrbuch der k. k. geolog. Reichsan 
stalt, vol. xliv., p. 472. 
In the paper last quoted a fine specimen of this species is stated to 
have been recognized by Dr. Kossmat in a part of Sir James Hectors 
collection from Nanaimo, now in the British Museum (Natural History) 
at South Kensington. It is difficult. however, to see how the Ammonite 
from Vancouver Island, which Mr. Gabb figures on Plate 27 of the first 
volume of the Paleontology of California as A. Wewberryanus, can be dis- 
tinguished from Pachydiscus Ootacodensis on the one hand, or from P. 
Suciensis (the Ammonites complexus, var. Suciensis, of Meek) on the other. 
This Ammonite has long been known to be quite distinct from Ammonites 
Newberryanus, Meek. An essentially similar specimen, which may there- 
fore be referable to P. Ootacodensis, was collected by Mr. Richardson in 
1873 at Northwest Bay, Vancouver Island. It is the specimen referred 
to as No. 2 on page 109 of the second part of the first volume of “ Meso- 
zoic Fossils,” published by the Geological Survey of Canada, under the 
heading Ammonites complexus, var. Suciensis.
