FOSSIL FISHES OF THE CHALK. 



The Secretary of the Society, Dr. A. Smith Woodward, gives 

 a further section of his magnificent work on the Fossil 

 Fishes of the Chalk. This is illustrated by a wonderful set of 

 plates shewing the palate teeth and other remains of fishes, 

 many of which are from Lincolnshire and other northern locali- 

 ties. He also figures and describes a fine skull of possibly a 

 new form of Pachyrhizodus, from the zone of Holaster suhglobo— 



Pachyrhizodus sp. ; lower portion of the head and opercular apparatus, left side view, 



nat. size Zone of Holaster subglobostts ; South Ferriby, Lines. Collected by Mr. H. C. 



Drake, F.G.S. Now in the Hull Museum.

sus at South Ferriby. This was obtained by Mr. H. C. Drake, 

 and is now in the museum at Hull. By the kind permission of 

 the Palaeontographical Society, we are able to give an illus- 

 tration of this interesting specimen. Fish remains, of course, 

 are not at all common in the northei'n chalk. Dr. Woodward 

 also refers to the rostrum of a species recently described as Proto- 

 sphyraena stebbingi, which Mr. T. Sheppard obtained from the 

 same locality. This specimen is more complete than the type 

 specimen, and Dr. Woodward kindly promises to describe 

 it shortly in The Naturalist. 



FOSSIL CHALK INOCERAMI. 



Mr. Henry Woods has a further instalment of his work on the 

 Cretaceous Lamellibranchiata, and in the present volume deals 

 exhaustively with those exceedingly difficult fossils, the 

 Inocerami. These oyster-like shells, from the enormous way 

 in which individuals of each species vary, have always been one 

 of the most difficult of the forms of fossils with which a student 

 and collector has had to deal ; and hitherto the lack of a detailed 

 monograph dealing with the genus has resulted in many workers 

 throwing the subject up in despair. In future, by reference to 

 this monograph, the study will be comparatively simple. Mr. 

 Woods describes a number of new forms, and we are glad to 

 see that Yorkshire has provided much material for his work. 

 A figure of one specimen, from the Upper Chalk of Yorkshire, 

 we are kindly permitted to reproduce (Plate XHI.).
