with the district at all. Barrois, who, over a quarter of 

 a century ago, accomplished so much during- his brief examina- 

 tion of the chalk of these islands, was particularly unfortunate 

 in his interpretation of the Yorkshire beds. Some of his errors 

 are perpetuated in the new memoir. Yorkshire geologists will 

 hardly agree with the suggested thickness of 402 feet for the 

 Marsupites zone (p. 285), or with the statement that the Hun- 

 manby fault ^ carries the chalk on one side below the alluvium of 

 the Vale of Pickering,' and they would like also to see specimens 

 of Marsupites from below the beds near Danes' Dyke (p. 284), and 

 the example of Ofiaster pillula (p. 289). Of particular interest 

 and value is the list of the fossils of the Upper Chalk of York- 

 shire, which appears to be the first fairly complete list published. 

 Economically, the volume contains much information of value ; 

 and there is a good ' general list of fossils ' and a Bibliography ; 

 but the Index is miserably poor, and the illustrations, parti- 

 cularly of the fossils, are a disgrace to a Government publication 

 of the twentieth century. - 



During his examination of the Yorkshire Chalk Dr. Rowe 

 obtained a curious Belemnite from the zone of Micraster 

 coranguiinim on Flamborough Head, the like of which he had 

 not previously seen, 'even in Yorkshire.' In an appendix to 

 Dr. Rowe's paper Mr. G. C. Crick describes this speci- 

 men. It is almost perfect, and is shown, natural size, in

 Association. Mr. Crick states : ' The affinities of the fossil are 

 quite clear, but whether it should be regarded as an abnormal 

 torm ot a known species, or a new species, or even a new genus,
