of very rough and primitive pottery. The flint implements from the 

 upper floor are all Aurignacian, and two specimens from a still later 

 deposit are clearly early Solutrean. The succession of the deposits 

 in the valley near Ipswich is therefore the same as that already 

 noted in the caves of France and Belgium. 



Flint implements of all ages since the appearance of man have now 

 been recognized in Suffolk, and Mr. Reid Moir has also published an 

 interesting and useful summary of these, with excellent illustrations 

 of the principal types, and a bibliography. We commend his paper 

 to those who desire a clear elementary statement of the subject.

 The Downtonian of South Staffoedsh[re. By W. Wickham

 Soc, vol. xiv, pp. 90-9, 1917.

By W. S. Boulton. Ibid., pp. 107-12, pi. viii. 

 rpHERE are three papers of special interest to geologists in the 

 X latest part of the Proceedings of the Birmingham Natural History 

 and Philosophical Society. Messrs. King and Lewis have continued 

 their researches on the Downtonian of South Staffordshire since their 

 contribution to the ^Geological Magazine in 1912 (Dec. Y, Yol. IX, 

 pp. 437, 484), and they now publish a detailed summary of their 

 results. They have found numerous fish-remains which determine 

 the age of the deposits with certainty ; and as these rocks are on the 

 faulted fringe of a great coal-field, a knowledge of their precise 

 sequence is of economic as well as of scientific importance. 

 Mr. Herbert Bolton describes three wings of insects from the Coal- 

 measures, probably of Coseley, one representing a new species of 

 Phyllohlatta, the others belonging to Brodia priscotincta. Professor 

 "W. S. Boulton gives an account of a sand-pit at Amblecote, 

 Stourbridge, in which teeth of Tlifpopotwmus have been found with 

 remains of Elephas primigenius, Rhinoceros antiquitatis, and Bison 

 priscus. All the bones and teeth are very fragmentary, but they 

 show little evidence of having been rolled or water-worn. Careful 

 search has been made for stone implements, but none have hitherto 

 been identified. The spot is evidently well worth continued 

 observation. 



YII. — The Phzlogent and Classification of Reptiles. By 

 S. W. WiLLisTON. Contributions from Walker Museum, vol. ii, 

 No. 3, 1917. 



PROFESSOR WILLISTON states that in this paper for the first 

 time he ventures to express in tabular form liis views as to the 

 phylogeny and classification of the Reptilia. As he remarks, he has 

 no startling novelties to offer, but nevertheless he makes a clear 

 statement of the results of recent work which will receive the assent
