the line of separation were found to be of Ordovician age, those 

 on the other side Upper Silurian. In the other case the fossils 

 from below were Silurian and, with only a slight interval between, 

 the strata above contained Carboniferous fossils. In the light of 

 such facts it would seem more reasonable to regard these white 

 limestones of New York and New Jersey as distinct from the 

 blue limestones of the same regions because of their persistent 

 lithological differences until actual evidence in the shape of fossils 

 proves their geological age. The presumption is in favor of the 

 theory of their different age until they can be shown to be con- 

 tinuous, and in the absence of such evidence it is unprofitable to con- 

 fuse them. A valuable List and Bibliography of the minerals 

 occurring in Warwick Township, by Hejnrich Hies, is appended 

 to the paper. — Granite at Mounts Adam and Eve, Warioick,

2. The Cretaceous Flora of Long Island. — Mr. Hollick has 

 increased our knowledge of this flora by descriptions of forty- 

 six gpecies, nine of which are new species, in a paper entitled 

 Additions to the Paleobotany of the Cretaceous formation on 

 Long Island. Bull. Torr. Bot. Club, by Arthur Hollick. Vol. 

 XXI, pp. 47-65 and Plates 174-180, Feb. 1894; and in a second 

 paper : Some further notes on the Geology of the North Shore of 

 Long Island, Trans. N. Y. Acad. Sci., xiii, pp. 122-132, 1894, has 

 shown the relations of 50 determined species, 23 species being 

 identified with species of the Dakota group, of western North 

 America, 16 also are identified with the lower Atane flora, and 

 7 with the Patoot flora of Greenland, and a few with other 

 fossil floras. 



3. A Monograph of the Devonian launa of the south of 

 England ; by G-. F. Whidborne. Vol. I, pp. 1-344 and Plates i- 

 xxxi ; Vol. II (parts i to iii), pp. 1-160, and Plates i-xvii. Pale- 

 ontographical Society, London, 1889-1893.— Prof. Phillips' " Pale- 

 ozoic Fossils of Devon and Cornwall," in 1841, defined the strati- 

 graphy and paleontology of the Devonian System of England, and 

 has since that time served as the basis for the identification of the 

 system in other regions. The faunas of the Rhenish Devonian, of 



.^theHartz, of Belgium and of France and Spain, of Kussia, and of 

 ' New York and several other tracts in North America have been 

 exhaustively studied, and described, while this typical fauna of 

 the Devonian has, as a whole, remained with little more elaboration 

 than it had fifty years ago. This monograph of Mr. Whidborne's 

 will therefore be of special importance in determining the precise 

 fauna of the original Devonian limestone. The author has con- 

 fined his descriptions to the fauna of the limestone of Lummaton, 

 Wolborough, Chircombe Bridge and Chudleigh : — thus restricting 

 the monograph to a single fossil fauna. When this shall have 

 been completed we will have before us a definite standard for 

 comparison and correlation.
