and marked only with fine transverse striæ of growth, while the umbili- 
cus is nearly if not quite closed. 
So far, only two species of Nautilus have been described from the 
Vancouver Cretaceous, viz., N. Campbelli, Meek, and MN. Suciensis, mihi. 
The character mainly relied upon for the separation of these two forms 
is the different position of the siphuncle in each, for the surface markings 
of WV. Campbelli are still unknown, and JV. Suciensis, although transversely 
ribbed in the adult state, is almost smooth when half-grown.

In the collection there are fourteen specimens of Baculites, varying 
from rather more than an inch to a little over five inches in length. 
Some of these are labelled “ Pemberton’s Bank, Nanaimo River,” and 
others “Stewart’s Bank, Comox Island, twenty-one miles northwest of 
Nanaimo.” They correspond to the “ Baculites compressus and two other 
species” of the list of fossils on page 434 of Sir James Hector’s paper, and 
to Nos. 23, 24 and 25 of the list on page 243 of Captain Palliser’s report. 
One specimen, labelled No. 24, is subovate or elliptically subovate in 
cross-section, and therefore probably referable to the typical form of B. 
Chicoensis, though its dorso-ventral diameter it so much greater than its 
maximum breadth that it seems to the writer, as it did'to Mr. Etheridge, 
to be more nearly related to Say’s B. compressus than to his B. ovatus. 
Four or five are trigonal in outline in cross-section, and correspond to the 
form for which Meek proposed the name B. occidentalis, but most of the 
specimens are intermediate in character between the typical form and 
this variety, and in all the dorso-ventral diameter, near the larger end, is 
much greater than the maximum breadth.

There are only three specimens of Ammonites in the collection received, 
and each of these is very imperfect. The most perfect is a specimen
