464 Reviews — Canadian Natural History. 



The descriptions are mainly based upon collections made by the late 

 Abbe Croizet and Prof. Bravard, which are now in the Paris Museum. 

 Partial descriptions of these fossils have already been given by pre- 

 vious authors ; but as these have in most cases been of a very sum- 

 mary character, and not infi-equently unaccompanied by figures, the 

 author has done good service to science in fully treating the subject. 



The remains have been discovered in strata referred to three 

 epochs, viz. the Middle Pliocene, Upper Pliocene, and Quaternary. 

 From the oldest deposits, mostly derived from the ' Montagne de 

 Perrier,' the author describes two species of the Antelope family, 

 one, Gazella borbonica, a small form allied to the diminutive Ante- 

 lopes from the Upper Miocene deposits of Pikermi, the other, Antilope 

 ardea, a larger animal, recalling by its dentition the Tragoceras of 

 Pikermi. The occurrence of a species of Gazelle in these Auvergne 

 deposits is of special interest from the fact that an apparently closely 

 allied species has been lately described by Mr. E. T. Newton^ from 

 the Norwich Crag, which is regarded by Desperet as synchronous 

 with the beds at Perrier. In addition to the Antelopes, the author 

 enumerates 10 well-defined species of Cervus from the Middle 

 Pliocene. This is a great reduction from the 24 species which 

 previous authors had described from the same deposits, many of 

 which are regarded as mere synonyms, based on differences of age. 

 The family of the Bovidae is represented by the single species Bos 

 elatus, Pomel. 



In the Upper Pliocene there have been discovered a single species 

 of Antelope and 3 species of Cervus, and from the Quaternary, 

 remains of the Reindeer [C. tarandus), Eed Deer (C elaphus), and 

 the Aurochs (Bison priscus). G. J. H. 



YI. — Thk Canadian Eecord of Natural History and Geology, 

 WITH Proceedings of the Natural History Society of 

 Montreal. Vol. I. No. 1. (Montreal, 1884.) 



THE above is the title of a new quarterly magazine, which, under 

 the editorship of Mr. J. T. Donald, is intended to replace the 

 "Canadian Naturalist," for many years the organ of the small but 

 active Natural History Society of Montreal. 



The main article in the present number is by Sir J. W. Dawson, 

 " On Rhizocarps in the Palccozoic Period." The author refers first 

 to the minute fossils described by him some time since under the 

 name of Sporangites Huronensis as probably spore-cases of macro- 

 spores of some acrogenous plant. They appear under the microscope 

 as yellow flattened disc-like bodies, about -25 mm. in diameter, 

 slightly papillate externally, and showing but little structure except 

 that the walls can be distinguished from the internal cavity. These 

 bodies occur in immense numbers in beds of dark bituminous shale, of 

 Devonian age, at Kettle Point, Lake Huron. They are also present 

 in beds of the same age in New York State, Ohio, and Indiana, and 

 occur at the slightly lower horizon of the Hamilton Shales and
