680 KEPORT— 1887. 



Professor Huxley once more taking up the pen and writing upon Hyperodapedon 

 and Rhynchosaurus in his old vigorous and earnest style. We can only regret that 

 liis health precludes him from continuous labour, to the no small loss of science. 

 Professor Marsh shortly promises us his memoir on the Sauropoda, the plates of 

 which are progressing rapidly to completion. 



Our late veteran chief, Sir Richard Owen, although retired from active official 

 duties, contributes a paper on Galesaurus planiceps, a Triassic saurian from South 

 Africa, and a further memoir on Meiolania from Lord Howe Island. 



Professor Seeley and M. Louis Dollo are both occupied with Dinosauria, the 

 former from the Cape (whence he has also detected part of a mammalian skeleton 

 in the Triassic rocks), and the latter is adding to our knowledge of Iguanodon and 

 other forms from the Wealden of Bernissart. 



In the Amphibia, Professor Dr. Herman Credner has added a most valuable 

 paper on the development of Branchiosaurus, a small Labyrinthodont from the 

 Keuper of Saxony, in which he has been able successfully to trace the development 

 through a long series of individuals of a water-breathing naked larva of the Palaeo- 

 zoic epoch into an air-breathing adult form, clad in a strong coat of mail. 



In fossil ichthyology, A. Wettstein has been occupied in the study of the Eocene 

 fishes of the Glarus slates, and in his recent memoir he shows that out of one fish 

 (Anenchelum), so constantly distorted by slaty cleavage, Agassiz had made no 

 fewer than six species. This fish is now found to be identical with the living 

 * scabbard-fish,' Lepidopus ; and the author reduces the forty-four species of Glarus 

 fishes to twenty-three and adds four new ones. Among the latter is the first fossil 

 Remora yet met with, named Echeneis glaronensis. Its first dorsal is modified as 

 a sucker, exactly as in the living Remora. 



Baron Zigno, of Padua, has figured and deseiibed the first entire Myliahatis, 

 hitherto discovered in the Eocene of Monte Bolca. 



M. Louis Dollo records the occurrence of two skeletons of Carcharodon heter- 

 odon in the Eocene of Boom, Antwerp, one measuring 7 metres, the other nearly 

 9 metres in length. They are now mounted and exhibited in the IBrussels Museum. 



Mr. J. F. Whiteaves is commencing to publish the detailed descriptions of the 

 Devonian fishes from Scaumenac Bay, Quebec. 



Mr. James "VVm. Davis, of Halifax, has produced a second monograph for the 

 Royal Dublin Society. The first, which appeared in 1883, was devoted to the teeth 

 and spines of Elasmobranch fishes from the Carboniferous limestone of Great Britain ; 

 the present monograph, illustrated by twenty-four plates, is devoted to the descrip- 

 tion of the fishes of the Cretaceous rocks of the Lebanon, and makes us acquainted 

 with a wonderful series of Selachian fishes, representing nine genera and sixteen 

 species, of which two genera and twelve species are new to science. The Ganoids 

 comprise two species of Pycnodonts and two forms related to Amia ; there are also 

 a number of Teleostean fishes, amongst which are Pagellus, liei-y.v, Ilomonotus, 

 Plata.v, and many other genera. Two species of eel, Angudla, are the first 

 Mesozoic examples recorded. Altogether we have ten genera and sixty-three 

 species of fish recorded as new. The author is to be congratulated upon having 

 contributed to fossil ichthyology one of the most extensive works published in 

 recent years. 



Mr. Arthur Smith "Woodward (a former student of Owens College, Man- 

 chester) has this year also contributed numerous papers on fossil fishes : on 

 Ptychodiis from the Chalk ; Squaloraja from the Lias ; on the Brazilian genus 

 Rhacolepis ; on a Maltese Holocentrum ; ' On some Eocene Siluroid Fishes from 

 Bracklesham ' ; and 'On the Canal-system in the Shields of Pteraspideau Fishes.' 



Mr. E. T. Newton describes a Semionotus from the Trias of Warwickshire. 



Both Mr. James W^ Davis and Dr. II. H. Traquair have given us 

 descriptions of the anatomy of Chondrosteus acipenseroides from the Lias of Lyme 

 Regis. 



Mr. William Davies describes two species of Pholidophorus from the Purbeck 

 beds of Swanage, Dorset. 



But the groups which have proved of the greatest service in the chronology of 

 the sedimentary rocks have been the Mollusca, the Brachiopoda, and Crustacea
