references are furnished to a bibliography at the end of the volume, 

 containing the titles of the principal memoirs &c. which have been 

 consulted. We are sorry to find that the author has not thought 

 fit even to mention Cheshire's treatise on ' Bees and Bee-Keeping ' 

 in his bibliography, although it is certainly entitled to rank as the 

 modern English classical work on the subject. The book is illus- 

 trated with a number of figures, most of which Mr. Cowan states 

 in his preface have been drawn for the purpose, while his indebted- 

 ness for others is duly acknowledged. Mr. Cowan's terminology is 

 at times a little shaky : it is unfortunate that his definition of the 

 word "inosculation" (p. 58) should allow the reader to infer that a 

 muscle is a " vessel ; " and until we read this book we had never 

 heard of vasa differentia, nor did we know that " Samenlf'ster " was 

 the German equivalent. The book is certain to be of much use to 

 the comparative entomologist as well as to the intelligent bee- 

 keeper. E. E. A.

" On a Labyrinthodont Skull from the Kilkenny Coal-Measures." 

 By R. Lydekker, Esq., B.A., F.G.S. 



The Author describes a skull from Jarrow Colliery, which he 

 refers to Ichihyerpetum, and names /. hibemicwm, giving reasons 

 for its specific distinctness from /. (Erpetocephalus) rugosum, Huxley. 

 He compares it with allied forms, and believes that it is a member 

 of the group Brachyopina of Miall, and if so that we have a number 

 of forms belonging to a type which is unknown above the base of 

 the Permian in Europe, but which survived to later times in the 

 Indian, Australian, and Ethiopian regions.
