529 Weller (Stuart). The succession of fossil faunas at Springfield, 
Missouri. 
Am. Jour. Sci., 3d ser., vol. xlix, pp. 185-199. 
The strata from which the fossils were obtained belong to the Burling- 
ton and Keokuk groups of the Mississippian series. The rocks are 
divided into twelve zones, and a brief description of the lithologic char- 
acter and a list of the fossils collected from each zone is given. Presents 
a table showing the raDge of the species in the different zones and 
groups. Considers that the faunas represent the Burlington and Keokuk 
and that they are continuous, and should be designated by a single name. 
(Osage group is said to be the name first suggested.) 
530 A circum-insular Paleozoic fauna. 
Jour, of Geol., vol. iii, pp. 903-917. 
Discusses and illustrates by two maps the distribution of land and 
w r ater during early Devonian time and at the close of Devonian time. 
Discusses the evidence of a union of eastern and western Devonian 
provinces and the generic and specific evidences of the origin of the 
littoral fauna of the Ozark Island. Presents a table showing the geo- 
logic and geographic range of the genera of the Chouteau group. 
531 Wheeler (H. A.). Note on the glacial drift in St. Louis [Mo.]. 
St. Louis Acad. Sci., Trans., vol. vii, pp. 121-122. 
Gives a brief description of an occurrence of glacial clay and gravel 
in the city of St. Louis. 
532 Note on the occurrence of blende in lignite. 
St. Louis Acad. Sci., Trans., vol. vii, pp. 123-125. 
Abstract : Eng. and Mg. Jour., vol. lix, p. 248. 
Describes an occurrence of blende-bearing lignite in a ferruginous 
sandstone and discusses its bearing on the origin of the Missouri zinc 
deposits. 
533 Recent additions to the mineralogy of Missouri. 
St. Louis Acad. Sci., Trans., vol. vii, pp. 126-131. 
Gives a list of minerals found in Missouri since the publication, in 
1881, of a paper by A. V. Leonhard, "Notes on the mineralogy of Mis- 
souri," in the Transactions of the St. Louis Academy of Sciences, vol. iv, 
p. 440.

Dakota formation, with descriptions of new inolluscan forms. 
U. S. Nat. Mus., Proc, vol. xvii, pp. 131-138, pi. viii. 
Reviews the previous descriptions of marine fauna of the Dakota, 
describes five new species from this formation in Nebraska, and discusses 
the evidence of the nonmarine character of the Dakota beds. 
535 The Bear River formation and its characteristic fauna. 
U. S. Geol. Surv.. Bull., No. 128, 86 pp., pis. xi. 
Reviews the history of the Bear River formation, discusses its taxo- 
nomic position, and describes its geographic distribution and the char- 
acteristics of its fossils. Includes a biologic discussion and a compari- 
son of Bear River fauna Avith other American fossil faunas. Discusses 
the geographic and time range of Pyrgulifera.
