1. On THE Skeleton or Ornithodesmus latidens: an Ornithosaijr 

 FROM THE Wealden Shales OF Atherfield, Isle of AVight. By 

 R. W. HooLEY. Quart. Journ. Geol. Soc, vol. Ixix, pp. 372-422, 

 pis. xxxvi-xl, 1913. 



In this important paper Mr. Hooley gives a very complete description 

 of a new species of Pterodactyl, founded mainly on a remarkable 

 specimen in which the bones are most perfectly preserved and quite 

 uncrushed. The author was ahle to remove the very hard matrix 

 to such an extent that he could find by actual trial the natural 

 motions of the bones on one another, and in this way to study the 

 mechanics of the reptile's wings. The type is a very remarkable one 

 and of great interest, because it represents an extremely large animal, 

 spread of wing about 5 metres, belonging to quite a different group 

 from the other well-known large types, the toothless Ornithosioma of 

 the Kansas Chalk. The paper concludes with a discussion of some 

 points in the structure of Pterodactyls and of their classification in 

 the light of this new type. 



2. Rekonstruktionen des Flugsaceiers, Reampeobhyncevs Gem- 

 3tiNGi, H. V. M. By Ernst Stromen, of Munich. Neues 

 Jahrbuch fiir Min. Geol. u. Pal., January, 1913, Bd. ii, S. 49-68, 

 Taf. iii-v. 



An important paper, dealing -with many points in the osteology of 

 Pterodactyls, illustrated by a beautiful drawing of a restoration 

 of the skeleton, and photographs of a remarkable life-size model of 

 the skeleton from three aspects, which give a much better idea of the 

 build of a long-tailed Ornithosaur than has previously been possible. 



3. On some New Genera and Species of Dicynodont Reptiles, with 

 Notes on a few others. By R. Broom. Bull. Amer. Mus. Nat. 

 Hist., vol. xxxii, art. xxvi, pp. 441-57. 



A description of three new genera and thirteen new species of 

 Dicynodont reptiles. The specific and generic characters are mostly 

 drawn from the features of the top of the skull in the pineal region, 

 particularly from the relations of the pre-parietal, which are illustrated 

 by clear figures. 



4. Note on Equus capensis, Broom. Bull. Amer. Mus. Nat. Hist., 

 vol. xxxii, art. xxv, pp. 437-9. 



A description of upper premolar (pm.*) of the large E. capensis, 

 which is found associated with the extinct Jios haini, Connochoetes 

 antiquus, Coins venterce, and human implements. 



5. On Evidence of a Mammal-like Dental Scjccession in the 

 Cynodont Reptiles. By R. Broom. Bull. Amer. Mus. Nat. 

 Hist., vol. xxxii, art. xxviii, pp. 465-8. 



Dr. Broom describes a specimen which appears to give satisfactory 

 evidence of the I'eplacement of canines, incisors, and milk molars 

 in DiademodoUf a discovery of very great importance, as hitherto, 

 although examples of Tlierocephalia, Gorgonopsids, and Cynodonts 

 showing replacements of the canine have been fairly common, and
