The skeleton of Astrosclera in many ways recalls that of the 

 extinct l^haretrorus, and Mr. Lister devotes a cousideraMe space to 

 the consideration of the possible relationship of the two groups, 

 but comes to the conclusion that there is no clear attinity between 

 them. 



The paper on AntroscUra is followed in the volume by a memoir 

 l)y Mr. \V. I'. I'ycraft, " On the Pterylography of the Megapodii," 

 dealing with the pterylosis of the adult, the nestling, and the 

 embryo. In the course of some remarks on the nature of the nest- 

 ling plumage, Mr. Pycraft advances the view that this does not, 

 in Meyajimiitis, consist of true ueossoptiles, but of a growth of 

 feathers intermediate between the latter and the detinitivo contour 

 feathers of the adult. Similar feathers are found in the nesiliug 

 owl. There are no preplumulae and the true prepennae are shed 

 during embryonic life. 



The remaining papers in the volume are respectively by Dr. D. 

 Sharp on the Insects from New liritain, by Mr. L. A. Borradaile 

 on the Stomatopoda and Macruru, by Mr. Walter CoUingo on the 

 Slugs, iliss Pliilipps on tlie Polyzoa, Miss Thornely on the llvdroids, 

 Professor Hickson and Miss lliles on the Stolonitera and Alcy- 

 onacea, and Dr. Ashworth on the Xeniidte, the whole series forming 

 a valualde addition to our knowledge of the zoology of the regions 

 visited by Dr. Willey. 



A MoHOijriiph of tht Coleoi^terous Families Corylophidae and 

 Sphieriida^. By the Rev. A. Mattuiws, M.A. Edited by Pqiup 

 B. M.4S0N, M.R'C.S., F.L.S., F.Z.S., &c. London : 0. E.' Janson 

 1899. 



This work is published in the same form as the author's previous 

 monograph on the Trichopter\ gida^. It consists of 220 pages of 

 letterpress, and is illustrated with nine plates in outliue, with 

 details of structure. One hundred and sixty-nine sptcies are 

 described. The author comludes that the affinity of the Corslophidse 



is with tlie SilphidiE and Leptinidie, and places the familiesthus : 



Leptinidfc, Corylophidae, Phaeuocephalida?, Silphida\ 



The Phoenocephalida} consists of a single genus, Phipnocq,h(du8, 

 separated from the Corylophidae on account of the maxilhe having 

 two lobes, &c. Aphanoct'i>hah(.s, originally described as a member 

 of the Cor)lophidae, is separated as a distinct family, Psendo- 

 corylophidae, chiefly on account of ti.e maxilUc having '' three lobes," 

 somewhat as in the Trichopterygidte. The family is j)!aced between 

 the Corylophidie and Phienoceplialidtc in the work, but the author 

 would "■ letain it in the position now occupied by the whole family 

 in the vicinity of the Coccinellidaj." This is a most interesting 

 point, for the Coccinellida.% formerly placed at the end of the 

 Coleoptera entirely away from the Clavicoruia, are now by some 

 eminent Coleopterists located with them. 



The various genera included in the Corylophidae are so diverse
