“Battle River” (Alberta), “near the Elbow,” July, 1858 : two good 
specimens of the left valve of shells of this species. These are both labelled 
“ Avicula,’ but without number, and are evidently the specimens referred 
to under that name on page 419 of Sir James Hector’s paper in the seven- 
teenth volume of Proceedings of the Geological Society of London. It is 
possible also that they may be the specimens from “ Bath” (a typographical 
error for Battle) “ River, near the Elbow,” referred to on page 243 of 
Captain Palliser’s official report as ‘‘No.101, Auricula rubrascensis,” an 
obvious misprint for Avicula (now called Pteria) Nebrascensis, as neither 
it nor P. linguiformis had then been figured.

“ Elbow of South Saskatchewan,” Assiniboia, September 20th to 30th, 
1857: three small and very imperfect specimens, the largest about three- 
quarters of an inch in length and not quite half an inch in maximum height, 
one labelled “No. 13, Cardium,” and the other two “No. 14, Exogyra,” 
which are somewhat doubtfully referred to this supposed variety of J. 
Crippsii. Two adult and much more perfect examples of a shell, which 
seem to the writer to agree very well with Meek’s description and figures 
of the western form which he calls Z. Crippsii var. Barabini, were collected 
by Professor Macoun at the Elbow of the South Saskatchewan in 1879. 
NucuLa. (Species undeterminable. ) 
“ Battle River,’ near the Elbow, July, 1858: a cast of the interior of 
a right valve, on a small piece of rock, associated with one example of 
Protocardia subquadrata, and an imperfect valve of a concentrically ribbed 
Mactra or Callista.
