2. A Review of the Evidence for the Taconic Revolution; by 

 Thomas H. Clark; Proc. Boston Soc. Nat. Hist., 36, 135-163, 

 1921. — The author finds but little orogenic evidence on which the 

 hypothesis of the Taconic Revolution of Dana (1863) can be 

 based. This evidence is restricted to the southwestern margin of 

 the New England mass from Otisville, New Jersey, north to 

 Becraft Mt., New York. "Beyond this region there is no evi- 

 dence of the Taconic Revolution." He does not deny epeiro- 

 genic movement and high land areas toward the close of the Ordo- 

 vician, resulting in thick formations of elastics of Richmonclian 

 and early Silurian times. c. s. 



3. Fossilium Catalogus, 1: Animalia. Pars 12, Ares, by K. 

 Lambrecht, Pars 13, Cnidaria triadica, by C. Diener. Pars 14, 

 Ammonoidea permiana, by C. Diener. 1921. — Part 12 of this 

 valuable work gives the more important literature on the known 

 fossil birds of the world, nearly 700 in number ; also the material 

 on which the species are based, the geologic horizon, the geo- 

 graphic locality, and the museum in which the material is kept. 

 The classification followed is in the main that of Piirbringer. 

 Part 13 cites the literature of 185 forms (in 33 genera) of Hexa- 

 coralla, 7(3) of Tetracoralla, 11(5) of Tabulata, 13(6) of Monti- 

 culipora, 1 of Alcyonaria, and 15(12) of Hydrozoa. Part 14 gives 

 a bibliography for 198 forms of Permian ammonites, in 41 genera 

 or subgenera. Seven of these genera also occur in the Carboni- 

 ferous and the same number pass into the Triassic. The author 

 also gives valuable remarks on their geologic and geographic 

 distribution. c. s.
