274 PALAEONTOLOGY. 



The following species have occurred: — Ursi^s (probably /^roo?), Hycena 

 spelcea, Canis lupus, C. vulpes, C. lagopus (axis), Gulo luscus (pelvis), 

 JBos primi(/enius, Cervus tarandu.^, C. megaceros, Ovis curies, Equus 

 caballusy Rhinoceros tichorinus, ElepJias primigenms, E. antiquus (?). 

 The Arctic fox {Canis lagopus) has not been previously found in any 

 British cave. The bones of the sheep appear to be recent. L. C. M.

Cope, Prof. Edward D. Synopsis of the Extinct Batrachia from the 

 Coal Measures. Geological Survey of Ohio, vol. ii. Palaeontology, 

 pp. 348-411, pis. xxvi.-xlv. 



Gives a synoptical and detailed account of the remains of Batrachians 

 found in the Coal Measures of Ohio, embracing 34 species, referred to 

 17 genera. After reviewing the general characters of the Batrachia 

 as a class, and defining its orders, proceeds to define the order Stego- 

 cephali [=:Lahyrinthodontia'], and defines 5 families of it. Describes 

 the genus Cocytinus,with. the single species C. gyrinoides, and the genus 

 Thyrsidium, with the species T. fascicidare, as both doubtfully referable 

 to the Proteida. Amongst the Stegocephali, the genera Phlegethontia, 

 Molgophis, Pleuroptyx, Oeraterpeton, Ptyonius, Q^stocephalus, Hyphasma, 

 Brachydectes, Pelion, Tuditanus, Leptophr actus, Eurythorax, Sauro- 

 pleura, and Colosteus eire treated of; and the following are described as 

 new, in addition to previously known forms : — Molgophis macrurus, M. 

 hrevicostatus, Fleuroptyx clavatus, Ceraterpeton tenuicorne, Ptyonivs 

 nummifer, Hyphasma Icevis, Tuditayius morclax, and Sauropleura 

 Newherryi. A short appendix treats of genera probably referable to 

 Fishes, namely — Peplorhina, with the species P. anthracina, and 

 Ctenodus, with the species C. ohioensis. H. A. N. 



. The Vertebrata of the Cretaceous Foimations of the West. 



Hep. U. S. Geol. Surv. Territories, vol. ii. pp. 1-302, pis. i.-lvii. 



Contains, besides prefatory matter, descriptions of the Cretaceous 

 Beptilia and Fishes of the Western Territories, and a synopsis of the 

 Cretaceous Yertebrata of N. America. The following genera (except last 

 two) and species are new : — Dinosauria : Cionodon stenopsis. Tesiudi- 

 NATA : Osteopygis erosvs, Plastomenus coalescens, P. costatus, Compsemys 

 ogmius, Toxochelys serrifer. Pisces : Pelecopterus chirurgus, Portheus 

 arcuatus, Enchodus dolichus, E. oxytomus, E. tetroecus, Leptomylus 

 forfex, Bryactinus amorphus, Diphrissa latidens, Ischyodus stenohryus, 

 I. tripartitus, I. longirostris, I. eoccenus, I. incrassatus, I. fecundus, 

 Isotcfnia neoccesariensis, Ptychodvs papillosus, Lamna macrorhiza, 

 L. Mudgei. 



Though there is comparatively little altogether new in this volume, 

 many of the genera and species appear for the first time with adecjuate 

 description and illustrative plates. The most important parts of the 

 text relate to Elasmosaurus, a Plesiosauiian ; to the author's order 

 Pythonomorpha, including Liodon and Clidastes, forms allied to Mosa-
