210 PROCEEDIXGS OF THE jVTALACOLOGICAL SOCIETY. 



]\[ar\vood and Pilton Beds of jS'orth Devon and Somerset," by our 

 member, the llev. G. F. Whidborne, is a useful epitome. The 

 systematic position of most of the species of Mollusca described 

 appears to us, however, doubtful, and this monograph will be of 

 best use later on, when the field comes to be more thoroaglily 

 Worked out. 



Carhonicola, Anthracomya, and Kaiadites form the subject of an 

 appendix to his previous work by Dr. Wheellon Hind, also a member 

 of our Society. There is given on p. 171a geological section of the 

 beds of the shore at Dalnieny, but its utility is seriously marred by 

 the omission of any statement as to the thickness of the beds. Dr. 

 Jiind also devotes eighty pages to the " British Carboniferous Lamelli- 

 branchiata " (Part I), dealing with the Mytilidae. The assignation 

 of a systematic position to many of the species of Lithodomus depicted 

 on pi. ii is, to say the least, bold. The greater part of this work is 

 confined to the "Introduction" and "Bibliography," which latter 

 "we could well wish revised and materially extended. 



Our member, Mr. W. H. Hudleston, P.R.S., contributes the ninth 

 number of Part I of his work on the " Jurassic Gastropoda," concluding 

 those of the Oolite. The monograph is accompanied by an alphabetical 

 index, showing geographical distribution in England. 



Our indefatigable Corresponding Member, M. Cossmann, has 

 published the second livraison of his great work " Essais de 

 Paleoconchologie comparee," comprising the Tubiferidoe, Icteriidic 

 (nov. fam.), and Nerineidae, which the author elevates into a new 

 suborder, Entomota'^niata. The systematic description of the 

 I'rosobranchiata is also commenced, and includes the Terebridtt;, 

 Pleurotomidte, and Conidoe. The work throughout bears evidence of 

 very careful preparation. A number of new genera and subgenera aie 

 proposed ; but we cannot say that the method of classification, thougli 

 it follows in part the example set by the late Paul Fischer in his 

 " Manuel," will be received with much satisfaction by English 

 students. One of the most interesting features of the work is the 

 careful manner in which the author cites examples of species oc- 

 curring along definite geological horizons, whereby the reader is 

 presented with a comprehensive review of the range in time of even 

 the subgenera and ' sections.' The work is destined to become 

 classical. 



There has also appeared during the year, under the direction of 

 M. Cossmann, a " Revue critique de Paleozoologie." It will appear 

 every three mouths, and is intended to contain comprehensive reviews 

 of current work. It to a certain extent takes the place of the pala3o- 

 zoological section of the recently defunct " Annuaire Geologique 

 Universel," and it cannot fail to be of the greatest use to us all. 

 M. Cossmann is to be congratulated on the undertaking. 



The Memoirs of the Geological Survey of India (" Palteontologia 

 Indica") of the year embody two important monographs on the 

 Cephalopoda, by Professor W. Waagen and Dr. Carl Diener. Dr. 

 Waagen deals with fossils of the Ceratite formation, which apparently 

 represents the Trias of Euiopp, although "it is not yet possible to
