Hab. Mexico : Jalisco. 



This is a very small species of which the two sexes do 

 not, as usual, differ iu the colour and sculpture of the elytra. 

 These are bright yellow, with dark margins, and very smooth. 

 The clypeus is less narrowed than in the other species of the 

 genus and straight in front, and the propygidium is not 

 hairy nor provided with the usual pair of stridulatory files. 



I have seen three specimens, only one of them a male, but 

 it is probable, in view of the small size of the species, that 

 the armature does not attain a much greater development 

 than that of the type. There is a sharp-pointed slender 

 horn upon the head, nearly as long as the thorax, but the 

 latter bears only a rounded elevation, grooved along the 

 middle, with a deep groove extending from it to the front 

 margin and containing a few yellow bristles. 



Golofa pusilla is the smallest known species, except 

 G. inermis, Thorns., which is strongly punctured and without 

 sexual armature. It is closely similar to G. tersander, Burm., 

 but quite differently coloured. 



BIBLIOGRAPHICAL XOTICE. 



A Descriptive Catalogue of the Manne Reptiles of the Oxford Clay. 

 Part I. By Charles William Andrews, F.R.S. London : The 

 Trustees of the British Museum, 1910. 



In this volume Dr. Andrews describes the wonderful collection of 

 Ichtbyosaurian and Plesiosaurian remains brought together during 

 years of patient labour by Mr. Alfred N. Leeds : a collection re- 

 markable for its completeness and the marvellous preservation of 

 the bones. Some of these skeletons were in such perfect condition 

 that they have been mounted as easily as if they had been obtained 

 from freshly macerated carcases. 



There is probably no one in this country so well qualified to 

 describe and interpret these remains as Dr. Andrews ; and this is 

 apparent on every page of this work, for it is obvious that vast 

 knowledge and ripe judgment are essential for such a task. 



The Reptiles which form the subject of Dr. Andrews's masterly 

 monograph are of peculiar interest to the evolutionist, and the 

 author in these pages has missed none of the evidence bearing on 

 this theme ; hence those who desire fresh evidence on adaptational
