514 SCIENCE PROGRESS 



From the preceding paragraph we are led by an easy 

 transition to pterodactyles, on which group, as represented 

 in the upper Jurassic strata of Swabia, Dr. Felix Plieninger 

 has contributed an important memoir to the Stuttgart Palceonto- 

 graphica (vol. liii., Nos, 4-6). Several beautifully preserved 

 skeletons from the Lithographic Stone of Nusplingen and other 

 Swabian localities are figured, for one of which the new name 

 Rhamphorhynchiis kokeni is proposed. The generic position 

 of the English Scaphirhynchus purdoni is also discussed at 

 some length. 



Having completed the survey of the extra-European Triassic 

 dinosaurs. Prof. F. von Huene has commenced in Geologische 

 und Palceontologische Ahhandlungcn (Jena, 1907) a detailed 

 description of their European representatives. The first part 

 is devoted to the dinosaurian remains from the Keuper of the 

 Nurenberg district, first brought to notice by Engelhardt in 1834, 

 and afterwards referred to Thecodontosaunts and Palceosaurus 

 of Riley and Stuchbury, which were long regarded as a general 

 receptacle for Triassic dinosaurs of all descriptions. Dr. von 

 Huene refers all the remains described in this part to von Meyer's 

 genus Plateosaunis, of which, in addition to the typical PL ciigcl- 

 hardti and PL qitciisfcdti, he recognises the new species PL 

 reinigeri and PL crlenhergiensis. 



A redescription of the type skeleton of the sauropod 

 dinosaur Morosaurus agilis forms the subject of a paper by 

 Mr. C. W. Gilmore in the Proceedings of the U.S. National 

 Museum (vol. xxxii. p. 151), in which it is suggested, on 

 account of the primitive character of the vertebral column, that 

 this species may belong to the genus Hoplocanthosaiiriis. To 

 the sauropod genus Pclorosaiirus, typified by a humerus from 

 the English Wealden, Mr. H. E. Sauvage {BiilL Soc. Boulogne- 

 sur-mer, vol. vii.) refers part of a femur from the Jurassic of the 

 Boulonnais ; also mentioning that the teeth from the same 

 deposit described as Neosodon and Caulodon likewise pertain 

 to the same genus. 



Dinosaurian remains from the Jurassic and (?) Cretaceous of 

 Madagascar have been described by Mr. A. Thevenin in the 

 Annales de Paleontologie, vol. ii. pt. 3. Some of these are referred 

 to Bothriospondylus fiiadagascarieiisis, a species described several 

 years ago by the present writer ; while others are assigned 

 to Titanosaurus and Megalosaurus. As Titanosaunts is typically
