Index to the Fossil llemahis of Avcs, Oriiithosauria, and Iloptilia,

 lUusrum of the University of Cambridge. ]5y H. G. Skelkv, of

The Woodwardian Museum holds a high place among Geological 

 Institutions. It has been enriched by the careful gatherings and 

 liberal gifts of tho venerable Woodwardian Professor, and by the 

 active cooperation and liberality of many University men and others 

 following so good an example. It is well housed and cared for by 

 the University and the Professor, as the illustrative material of the 

 Cambridge school of Geology ; and the well printed volume before us 

 not only enhances the usefulness of the museum to students, but, 

 as a classiticatory catalogue of its precious collection of Keptilian 

 remains, carefully allocated and critically determined, it supplies a 

 standing-ground for herpetologists, whether working out their own 

 \'iews of the alliances of recent and fossil Eeptiles, or following the 

 plan of research indicated by Mr. Seeley's proposed relationsliips of 

 the numerous osseous relics of new or ill-understood genera and 

 species. Mr. Secley sepai'atcs the Pterodactyles and their fellows 

 from the Reptilia as " Ornithosauria " (Pterosauria), and regards the 

 Birds as an intermediate group. His views on the Pterodactyles arc 

 published in the ' Annals of Nat. Hist.,' and the specimens which ho 

 has already illustrated and described are indicated in this catalogue. 

 Very many specimens described and figured by Professor Owen in 

 the monographs of tho Palaiontographical Society are in this collec- 

 tion and are duly noted. 



From the several tables in the List of Contents, pp. xi-xxiii, the 

 reader gathers much information ; thus there are : — 1. The *' Table 

 of the Distribution of the large Groups of Animals in the Secondary 

 Strata," as far as the mass of material in the Cambridge collection 

 shows. 2. " Table of Secondary Strata, sho\ving the larger Groups 

 of Animals which they contain," as illustrated by the same collection ; 

 and it is rich in these osseous fossils from the Chalk, the Cambridge 

 Upper Greensand, Gault, Potton Sands, Wealden Series, Purbcck 

 Series, Portland Stone, Kimmeridge Clay, Coral-rag and AmpthiU 

 Clay, Oxford Clay, Great Oolite, and Lias. 3. " An approximate 

 List of the Species included in the catalogue, with provisional 

 names for new species and reference to the specimens on which 

 they are founded, and to the pages of the Index in which they 

 are described." These are arranged according to the geological for- 

 mations. Thus from the Chalk we find one new species of Ichthyo- 

 saurus ; from the Upper Greensand seventeen new species of a new 

 Pterosaurian genus (Ptenodactylus), which comprises some of Owen's 

 Pterodactyli, whilst another, accompanied by two new species, falls 

 into Seeley's new Ornithocheirus. Enaliornis is a new bird-genus
