[WHITEAVES] PALLISER’S CRETACEOUS FOSSILS 103 
Some of the specimens from the Red Deer River, abovethe Nick 
Hills, referred to on page 426 of Sir James Hector’s paper 
as “concretionary masses of limestone, filled with fresh-water 
shells, such as Paludina, Planorbis, ete.” and in the first list 
of specimens on page 244 of Captain Palliser’s report as 
containing shells of “ Paludina, Unio, Planorbis and Cyclas.”" 
From THE ELBOW OF THE SOUTH SASKATCHEWAN. 
Astarte Texana, No. 15, and Cytherea, No. 16, of the list on page 
243 of Captain Palliser’s report.

MANITOBA.

Inoceramus Texanus, Inoceramus confertim-annulatus and Ammo- 
nites geniculatus, being Nos. 18, 21 and 28 of the list on page 
243 of Captain Palliser’s report. 
Many of the specimens sent are labelled with two or more numbers, 
but in the present paper only those will be referred to which obviously 
correspond to the numbers in the lists of specimens on pages 242-244 of 
Captain Palliser’s report. 
It will be convenient to consider these fossils in the following order: 
A, those from the Laramie formation of Assiniboia and Alberta ; B, those 
from the Pierre-Fox Hills or Montana formation of the Plains; C, those 
from the disturbed region of the foot-hills and eastern flanks of the Rocky 
Mountains; and, D, those from the “Nanaimo group” of Vancouver 
Island.

1 Two small pieces of limestone were sent from this locality. One of these con- 
tains a few specimens of a shell which appears to be Campeloma productum, White, 
and the other, two badly preserved casts of the interior of a species of Viviparus.
