422 Reviews — The Lower Cretaceous Floras of Queensland. 



figures ; amongst these latter may especially be referred to figs. 36-9 

 and 41, the restorations of the skeletons of Pleuropholis formosa, 

 Leptolepis dubius, and Lepidotus minor, as fine examples of delicate 

 drawings by Miss G. M. "Woodward. So far as known, the fishes 

 of the Wealden and Purbeck formations are essentially Jurassic and 

 not mingled with any typically Cretaceous forms. Most of them are 

 indeed (in the author's opinion) specialized and evidently final 

 representatives of the Jurassic families to which they belong, not to 

 be regarded as possible ancestors of the fishes of Cretaceous and 

 later times. 



2. The index and title-page complete the first volume of 

 Mr. F. W. Harmer's great work on the "Pliocene Mollusca of Great 

 Britain", with a systematic list of genera and species (pp. xii and 

 463-83). A view is added of the pit of " Waltonian " Crag at Little 

 Oakley from which the author obtained the shells of about 650 

 species of Mollusca and upwards of 100 specimens of Polyzoa. This 

 concludes the Crag volume for the year. 



3. Dr. W. Spencer follows with part iv of his monograph on 

 British Palseozoic Asterozoa (pp. 169-96), illustrated by twenty-five 

 text-figures of anatomical details of living and fossil forms, which 

 greatly assist the student in understanding the structure of these 

 very interesting organisms and their life-history and functions, so 

 that the dry bones of the Palseozoic starfishes, interpreted by their 

 modern representatives, live again. 



4. Mr. Philip Lake adds part v of his monograph on the British 

 Cambrian Trilobites with four excellent plates and 31 pages of text, 

 embracing Ctenopyge, Leptoplastus, Eurycare, Peltura, Beltella, Para- 

 lolinella, Angelina, Dikelocephalns, Dilcelocephalina, and Apato- 

 kephalus. Mr. T. A. Brock's figures are excellent. 



We trust the splendid work carried on by the Palseonto graphical 

 Society may not be permanently hindered by the evils arising as an 

 " aftermath" of the War, which has affected the cost of printing and 

 publishing of all scientific work more or less severely.
