[WHITEAVES] PALLISER’S CRETACEOUS FOSSILS 117 
about six inches and a half in its maximum diameter, labelled “ Ammo- 
nites, Pemberton’s Bank ” (Nanaimo River). It is septate throughout, but 
so much of the outer volution is worn away that its original shape is 
completely destroyed, though the inner volutions are well preserved, and: 
judging by these, the species would seem to be referable to Zittel’s genus 
Pachydiscus. It resembles the Ammonites Newberryanus of Meek very 
closely in shape, but differs therefrom in its much fainter, almost 
obsolete and more distant transverse ribs; also in the absence of the 
periodic constrictions so characteristic of A. Newberryanus. It is, ap- 
parently, a much flatter shell than the Ammonites Suciensis of Meek (which 
is clearly a Pachydiscus), and has a sutural line more like that of A. New 
berryanus. Another specimen, labelled “ No. 26,” is a fragment of the- 
earlier whorls of a round-backed Ammonite about an inch in its greatest 
diameter ; and the third, labelled “ Ammonites, Comox Island,” is a rather 
large but quite worthless waterworn fragment. 
Since the foregoing part of this communication was written, the 
writer has received from Dr. Franz Kossmat a separate copy of his inter- 
esting paper “On the importance of the Cretaceous rocks of Southern 
India in estimating the geographical conditions during later Cretaceous 
times,” published in a recent number of the Journal of the Royal Geo- 
logical Institute of Vienna.' In this paper Dr. Kossmat says that he saw 
in an old and still unstudied collection of Hector’s, in the British Museum, 
a beautiful specimen of Ammonites Indra, Forbes, the typical Pachydiscus 
Otacoodensis (new to North America) of the Arrialoor group, besides 
others, some of them new species of Pachydiscus, and Baculites occidentalis, 
Meek, which is very similar to the Indian B. vagina, all from rocks of the 
age of the Chico group of Calitornia or Vancouver Island.
