Interior United States Geol. Surv. (George Otis Smith, Director), 
Bull. 598, pp. 50, pls. i-i1i, 1915. 
1: is pointed out in this account that the Boone Limestone includes 
all the Mississippian rocks of Northern Arkansas and Southern 
Missouri, comprising equivalents of the Kinderhook, Burlington, and 
Keokuk formations farther north, while the St. Joe Limestone forms 
the base of the Boone Series. The Boone Limestone fauna consists of 
Corals (Amplexus), Bryozoa (Lenestella, etc.), Brachiopoda (Leptena, 
Productella, Spirifer, Reticularia, Athyris, etc.), Pelecypoda ( Cypri- 
cardinia), Gastropoda (Platyceras), Cephalopoda ( Celonautilus), 
Trilobita (Brachymetopus). The following are described as new 
species: Polypora, n.sp., Hemitrypa, n.sp., Chonetes ornatus, var. 
arkansanus (= new var.), Productella semicostata, P. patula, P. malle- 
spinosa, Rhynchopora pingus, Cypricardinia rugosa, Cardiomorpha 
orbicularis, and Brachymetopus (?) elegans. The fauna of the St. Joe 
Limestone as observed at St. Joe is also described. It is composed of 
about forty species, including’ Corals (Zaphrentis, Cyathaxonva, etc.), 
Echinodermata (Crinoids), Bryozoa (fstulipora, Cystodictya, Henes- 
tella, etc.), Brachiopoda (Leptena, Chonetes, Productus, Productella, 
Camarotechia, Shumardiella, Spirifer, etc.), Gastropoda (Platyceras). 
The author has recognized as new species Fistulipora rubra and 
Camarophoria simulans.

1X.— Borrom Conrrot or MartnE FAUNAS AS ILLUSTRATED BY DREDGING 
In THE Bay or Funpy. By E. M. Kinpie. American Journ. Sev., 
vol. xl, pp. 449-61, 1916. 
\ ane paper contains some important considerations on the influence 
of environment with regard to marine faunas living on sea- 
-_ bottoms, molluscan life being more particularly alludedto. A number 
of shells obtained from dredgings in the Bay of Fundy are tabulated, 
the species having been obtained from differently constituted sea- 
bottoms which are referred to as: Boulders and Sand, Boulders and 
Gravel, Black Mud, Sandy Mud, Rocky and Sandy bottom, ete. The 
author recommends the paleontologist, when using fossils for purposes 
of correlation, to ‘“‘recognize and bear in mind the close relationship 
between the physical texture of the bottom and the kind of life living 
upon it’’.

X.—Fossiz Contectine. By E. M. Kinpiz. The Ottawa Naturalist, 
woke xxix, Nos10; pp. 117=24, 1916: 
HE author suggests a number of collecting methods when obtaining 
fossils for study purposes, emphasizing, of course, the importance 
of precise localities being attached to each specimen, and the 
particular bed of the section being noted from which the fossil was 
procured. The measurement of strata by means of a spirit-level 
clinometer is also recommended. Remarks are made on paleography, 
and suggestions offered that complete data should be furnished
