II. Geology. 



1. The Devonian Faunas of the Northern Shan States ; by 

 F. R. Cowpee Reed. Mem. Geol. Surv. India, Pal. Indica, n. 

 ser., II, pp. 183, pis. 20, 1908. — This welcome work on the 

 Middle Devonian faunas of Burma describes 165 forms from 

 Padaukpin and 30 from Wetwin. About 120 species are named 

 specifically and of these 34 are new. Corals, Bryozoa and Braehi- 

 opoda constitute the bulk of the fossils. The author also reviews 

 all other Asiatic Devonian faunas. The majority of the species 

 are clearly western European and of the Calceola sandalina fauna. 

 There is nothing present to remind one of the Middle Devonian 

 faunas of eastern North America and but little that recalls our 

 western faunas having Euro-Asiatic connections. The Wetwin 

 fossils remind some of the New York Portage biota, but as their 

 preservation is not good and the fauna a small one, not much 

 value can be placed on this slight resemblance. c. s. 



2. Osteology of the Jurassic reptile Camptosaurus, with a 

 revision of the species of the genus, and descriptions of two new 

 species ; by Charles W. Gilmore, Proc. U. S. National Museum, 

 vol. xxxvi, pp. 197-332, with pis. 6-20 and 48 figures in the 

 text. — This is an important contribution to our knowledge of 

 American dinosaurs, to which subject Mr. Gilmore has devoted 

 especial attention. After a brief historical review of the genus, 

 Gilmore discusses at some length the osteology of Camptosaurus 

 as shown mainly in the type specimen of C. browni, a new species. 

 The generic definition follows with an alphabetical list of species. 

 In the systematic description and revision of species, Gilmore 

 accepts as valid all four erected by Professor Marsh, to which he 

 adds two others, one from the Morrison and one from the Lakota. 

 Of the four European forms referred to this genus the author 

 admits but one, Camptosaurus prestwichii from the Kimmeridge 

 clay. Camptosaurus is evidently allied to the European Iguano- 

 don, but is a more archaic type and suggests a somewhat greater 

 age for the beds in which it is found. Gilmore thinks that the 

 evidence shown by the Carnptosauridse not only supports the 

 contention that the lower members of the Morrison (Atlanto- 

 saurus Beds) are below the Wealden, but that they are of greater 

 age than the Purbeck and possibly equivalent to the Kimme- 

 ridgian. 



Two restorations of the animals are given, one, that of 

 Professor Marsh, the other a photograph of a specimen of 

 Camptosaurus nanus in the American Museum of Natural 

 History. The former restoration is in error principally in show- 

 ing too many presacral vertebras, giving the animal too long a 

 back. 



Nothing is said of probable habits, but Mr. Gilmore is of the 

 opinion that a quadrupedal mode of progression was the more 

 habitual. k. s. l.
