of the Queen Charlotte Islands and British Columbia. 447 
States and Territories entitle any views he may express on such 
subjects to the fullest consideration, and his intimate acquaint- 
ance with and ready access to Meek’s types from the Black 
Hills are unquestionably a great advantage. Unfortunately, 
however, Dr. White could only spare part of a single day for 
the examination of the large series of Mesozoic and Laramie 
fossils in the Museum of the Canadian Survey at Ottawa, and 
only a few minutes each to a study of those species whose iden- 
tification he objects to. 
o the general statements made at the commencement of Dr. 
White’s paper no special exception need be taken here except 
perhaps on the ground ef their want of novelty. They are, in 
effect, a résumé of that part of Clarence King’s volume on the 
“Systematic Geology” of the United States Exploration of the 
40th Parallel which treats of the Jurassic rocks. In that vol- 
ume, however, Prof. King distinctly states that the Dakota and 
“Jurassic” rocks are conformable in the Wahsatch Region, 
also that according to Meek, Hall and Whitfield, the “Juras- 
sic” fossils from the east base of Augusta Mountain have “a 
Cretaceous and even an Eocene look.” 
To Dr. White’s presentation of the statements and arguments 
on the other side of the question the writer begs respectfully to 
emur, 
White says that in the memoir which he criticizes the 
Dr. 
author thereof “ describes and figures some fossils” . 
but also with the precise subdivision of the series in which it 
was found. ; 
Out of the twelve forms collected by Dr. Dawson which the 
writer has referred to North American “ Jurassic” species, Dr. 
White objects to the identification of nine, and with regard 
to these the following remarks are submitted : 
- Belemnites densus Meek and Hayden. The specimens de- 
scribed by Mr. Meek under this name are represented as being 
short and thick or long and slender, as having an apical groove, 
a median groove or no groove at all. Dr. ite says that 
“Mr. Whiteaves’ collection contains only one specimen which 
he refers to this species,” whereas there are two of the short and 
thick form, seven of the long and slender variety (to which in 
accordance with a suggestion of Mr. Meek’s, the writer gave a 
local and provisional name) and several large phragmocones.
