SYNOPSIS OF DINOCERATA. 



The present synopsis contains a list of all tlie known species of the 

 Dinocerata, and at least one characteristic figure of each species not 

 elsewhere illustrated in this volume. Full references, also, are given to 

 all the important literatxu-e. The complete titles of the works cited will 

 be found in the Bibliog-raphy, which follows this synopsis. A brief 

 history of the discovery of each specimen of importance, with the locality, 

 geological horizon, collector, date, the natui-e of the remains, and where 

 now preserved, is likewise placed on record under each species, as an 

 essential pai-t of a Monograph of the group. 



The dates of publication of the various papers on the Dinocerata have 

 been carefully reexamined, and those here given are substantiated by 

 conclusive evidence.^ ^ The^ names adopted for genera and species are 

 based on priority alone, except in the cases of those already used. For 

 the higher groups, the new names proposed are to replace those previously 

 applied, or to gain appropriate terms for nomenclature. Amhlydactijlu has 

 thus been substituted for Amblypoda, and Coryphodoutia, for Fantodonta, 

 the names replaced being both essentially pre-occupied. The last term, 

 moreover, has no significance when applied to the group of which 

 Coryplwdon is the original and characteristic type. The names Profiuigidata, 

 Holodactyla, ■Aud Clinodadyla, express, respectively, a prominent feature of 

 the groups they represent, and hence have been introduced in the 

 preceding chapter.
