Dr. Whiteaves (Geol. Survey of Canada, Vol. I, Part IV) revises 
his published papers on the paleontology and stratigraphy of the 
Queen Charlotte Islands, many old species being renamed, as further 
studies have shown their designations to be untenable. Several new 
species of brachiopods and Mollusca have been obtained by later col- 
lectors and are added in this paper. Among the ammonites may be 
noted the predominance of Desmoceras and Olcostephanus, also the 
absence of Baculites and Pachydiseus, which are characteristic of the 
Cretaceous of Vancouver Island. The faunas here described seem 
to include both Knoxvile and Horsetown beds of the Californian 
section, as shown by such characteristic species as Phylloceras knox- 
villense Stanton, Lytoceras batesi Trask, L. sacya Forbes, Desmoceras 
breweri Gabb, D. haydeni, and Aucella crassicollis Keyserling. 
The revision of the nomenclature will be exceedingly acceptable 
and useful to students of West-Coast stratigraphy. 
Dr. Sokolow (Mem. Comité Geol. St. Petersburg, Vol. IX, No. 5, 
1899) has made an interesting study of the brackish-water basin 
fauna that lies immediately between the Mediterranean stage of the 
lower Miocene and the Sarmatic stage of the middle Miocene Ter- 
tiary of Russia. The Mediterranean stage represents the deposits 
of the disappearing ancient Mediterranean Sea, and the Sarmatic 
beds are the deposits of the ancient Black Sea. In this paper we 
have a study of the fauna transitional between the two epochs and 
the two basins. In consequence of this the fauna is a mixed one, - 
showing both marine and brackish-water types, due to the rapidly 
changing physical geography and the development of the extensive © a 
brackish-water seas that covered southern Russia in later Miocene 
time. 
Most students of the Triassic paleontology of the Alps occupy — 
themselves with the cephalopods, while the other groups are 
neglected. But Dr. Kittl (Ann. k. k. Naturhist. Hof Museum —— 
Wien, Bd. XIV, Nr. 1, 2) has given an elaborate revision of the — 
gastropods of the classic St. Cassian beds of the southern Alps — 
describing many new species and making known a rich fauna. — ber ue 
detailed stratigraphy and correlation of these beds are taken up, xs 
much new light is thrown on the relations of the various fossiliferous — ' 
horizons of the southern Alps. |
