Regis. As the Liassic species is almost certainly distinct from 

 those of the superior formations, it may be appropriately 

 designated Megalosaurus woodwardi, with the tooth from Lyme 

 as the type. Dr. Woodward has also shown, in the Geological 

 Magazine for May, that the limb-bones from the Greensand of 

 Hythe, described by Owen as Dinodocus mackesoni and regarded 

 as sauropterygian, really indicate a gigantic sauropod dinosaur. 



Evidence is gradually accumulating to show that during the 

 middle of the Secondary epoch the dinosaurian reptiles ranged 

 over the greater part of the world. They occur, for instance 

 (mostly as isolated bones), all over temperate Europe, in both 

 North and South America, in Madagascar, and now they have 

 turned up in East Africa. Dr. E. Fraas, of Stuttgart, has 

 recently published (Mitteilungen Nat.-Kabinctt, Stuttgart, No. 61, 

 1908) an account of a large portion of the skeleton of a monster 

 of this kind which he brought back from German East Africa. 

 Some of the bones appear to have been lying on the ground, 

 but others were dug up at a short distance below the surface. 

 They comprise a number of the vertebrae, the haunch-bones, 

 and most of the bones of the hind-limbs, inclusive of the huge 

 claw-bones of the feet. As the thigh-bone measures close upon 

 a yard and a half in length the African monster (for which the 

 name Gigantosaums, despite its having been previously used for 

 a dinosaurian bone from Cambridgeshire, has been proposed) 

 must have rivalled Diplodocns in point of size. The memoir 

 is illustrated by the reproduction of a photograph showing the 

 bones as they lay on the ground in front of the party of natives 

 by whom they were disinterred ; and there seems little doubt 

 that the whole of the skeleton must have been buried in the 

 same spot, together with one of a second species. And where 

 one or two skeletons have been found others ought to occur in 

 the neighbourhood. Dr. Fraas is on his way to German East 

 Africa for the purpose of collecting other specimens. 



Passing from dinosaurs to crocodiles, we find that Mr. L. M. 

 Lambe has contributed a paper to the first volume of the third 

 series of the Transactions of the Royal Society of Canada on the 

 remains of a new type of crocodile from the Cretaceous formation 

 of the Judith River. This crocodile, for which the uncouth name 

 Leidyosuchus canadensis is suggested, is a broad-nosed type 

 recalling the European Oligocene genus Diplocynodon, but with 

 the splenial included in the short mandibular symphysis, as in
