of the Judith River beds. 
Bull. U.S. Geol. Surv., No. 257, 1905, pp. 
129-168, pls. XIV-XIX. 
The specimens described by Mr. Knowlton 
are contained in the Museum collections, 
having been transferred from the U. 8. Geo- 
logical Survey. The paper enumerates and 
describes 28 forms, 16 of which arenew and 5 
not specifically described. From his review 
of these forms he states that the flora of the 
Judith River beds, so far as now known, 
shows very little affinity with the true Lara- 
mie or with the Fort Union, but that it does 
exhibit an undoubted relationship with that 
of the Dakota Group, or with the Cenomanian 
and Senonian of the Old World; that is, with 
the lower and middle portions of the Upper 
Cretaceous.

REPORT OF NATIONAL MUSEUM, 1906. 
ScHucHERT, CHARLES. Catalogue of the 
type specimens of fossil invertebrates in 
the department of geology, U. S. Na- 
tional Museum. Assisted by W. H. 
Daut, T.W.Sranton, and R. 8. BAssuEr.

30, 1905, pp. 1-704. 
This section of Bulletin 53 records the type 
material of invertebrate fossils in the U.S. 
National Museum. The introduction by 
Charles Schuchert contains a general discus- 
sion and classification of type specim2ns, with 
descriptions of the various kinds of primary 
and supplementary types and definitions of 
new type terms. Typical specimens, types 
of genera, marking of type material, and 
other more general subjects are discussed. 
The introduction closes with a list of the 
literature on type terms. 
In the catalogue proper the types are re- 
corded under the names as originally de- 
scribed. Subsequent descriptions of the same 
species under different names are referred to 
by cross references, while the present place- 
ment of the listed type, if different from the 
recorded reference, is likewise denoted.

Malone Mountain and the surrounding

23-33. 
Describes the Jurassic and Cretaceous rocks 
in a limited area lying between the Sierra 
Blanca, El Paso County, Tex., and the Rio 
Grande. The Jurassic rocks are those of the 
Malone formation yielding the fauna de- 
scribed by F. W. Cragin, and the Cretaceous 
is mostly referable to the Comanche series, 
though in fact somewhat different from the 
usual facies. 
The Morrison formation and its 
relations with the Comanche series and 
the Dakota formation. 
Journ. Geology, X11, 1905, pp. 657-669. 
It is shown that the Morrison formation, 
long known as the Atlantosaurus beds, passes 
beneath the marine beds of the Comanche 
series in southwestern Colorado and adjacent 
portionsof New Mexicoand Oklahoma. The 
attenuated marginal deposits of the Coman- 
che series in this region have often been 
referred to the Dakota formation with which 
they are intimately associated, although 
there is some evidence of an unconformity 
between them.
