Of the Gepleslbpots. 1 most have been recognized in Alabama 
and Texas. Of the Eocene Gastropods, ten occur in Alabama. 
Of the two hundred and twenty-two species of Lamellibranchi- 
ates, seventy-four of them are new species; and of one hundred 
and ninety species of Gastropods, one hundred and seven are new. 
Comparison permits the conclusion arrived at before by others 
on less extensive determinations, that the New Jersey Cretaceous 
Marls are the equivalent of No. 4 or of Nos. 4 and 5 of the 
Upper Missouri Section. 
The work done on the Cretaceous is yet fragmentary, as many 
specimens are too imperfect for use, and the middle and base of 
the upper marls have not been systematically examined.—R. P. 
Whitfield. 
Geological ace: GENERAL.—A catalogue of the Blastoidea 
in the Geological Department of the British Museum of Natural 
History is the joint work of Mr. R. Etheridge and Mr. P. H. Car- 
penter. The Blastoids are given a position as a group equivalent 
in rank to the brachiate Crinoids. The term Pelmatozoa, or 
palmed animals, includes the crinoids and cystids, and the class 
Blastoidea have the following peculiar characters among others: 
A subambulacral a which is pierced by a canal that
