The crista sagittalis is well developed and extends forward 

 over the whole parietal and posterior portion of the frontal. 



The cranial measurements of this species appear to be 

 considerably larger than in any other species of this group, 

 and as the colour as well is very distinct, it seems to be a 

 very easily recognized animal. 



BIBLIOGRAPHICAL NOTICE. 



Index Zoohgicus No. II. An AJphahetkal List of Names of Genera 

 and Subgenera proposed for Use in Zoology, as recorded, in the 

 ^ Zoologiccd Record,'' vols. 38-47 inclusive {1901-1910), and the 

 Zoology Volumes of the ' International Catalogue of Scientific 

 Literature,^ Annual Issues 1-10. together with other Names not 

 included in previous Nomenclators. Compiled (for the Zoological 

 Society of London) by Chaeles Owen WAXEEHorsE, I.S.O., and 

 edited by David Shaep, M.A,, F.R.S., Editor of the ' Zoological 

 Pi.ecord.' London, 1912. 



Me. C. 0. "Wateehouse's ' Index Zoologicus,' pubHshed by the 

 Zoological Society in 1902, is known to every systematic zoologist 

 as an indispensable supplement to the indispensable " Scudder," 

 and he has once again earned the gratitude of the zoological world 

 by his ' Index Zoologicus No. II.,' covering the years 1901-1910. 

 Like the former volume, this is far more than a mere combinatiou 

 of the indexes of successive volumes of the ' Zoological Record.' 

 A very large number of names omitted from previous nomenclators 

 have been included, with, in nearly all cases, a reference to the 

 original source. No fewer than 774 of these omitted names have 

 been discovered by Mr. Waterhouse himself. From the editor's 

 preface we learn that the total number of generic and subgeneric 

 names proposed for use in zoology is estimated at 140,000, of 

 which about 62,000 are indexed in Mr. Waterhouse's two volumes. 

 These figures give some measure of the extent to which he has 

 lightened the burden of future bibliographers.
