of its variations from the taxonomic point of view {Para- 

 sitology, vol. viii. No. i, 1915). 



Two further notes on descriptions and records of bees add 

 to the already long series that have been made by Cockerell 

 (Ann. and Mag. Nat. Hist. April and June 1915)- Smith has 

 a paper on the genera Eglisia, Callostracum, Mesalia, Turri- 

 tellopsis and Trachyrhynchus (Ann. and Mag. Nat. Hist. April 

 191 5). The gill-chamber of land-crabs appears to furnish a 

 convenient resting-place for a number of different parasites 

 that have been described by Bayliss, and include, strangely 

 enough, an Oligochaete (Ann. and Mag. Nat. Hist. April 191 5). 

 Two papers concern new species of Coleoptera ; one by Arrow 

 deals with those belonging to the Dermestidae from the collec- 

 tion in the British Museum together with notes on that family 

 (Ann. and Mag. Nat. Hist. May 191 5) ; the other, by Lee, de- 

 scribes certain Malacodermidae and Curculionidae that were 

 obtained by Mr. Bryant in Australia (ibid.). In the same 

 publication Bergroth catalogues new Oriental Pentatomoidea, 

 Distant some Rhynchota hitherto undescribed, andSchaus gives 

 a long list of corrections in the nomenclature of Heterocera 

 from Costa Rica that have previously appeared in the Annals 

 and Magazine of Natural History. Bagnall treats of a small 

 collection of Symphyla from Algeria (Ann. and Mag. Nat. 

 Hist. May 191 5), and of new Thysanoptera (Ann. and Mag. 

 Nat. Hist. June 191 5). Fossil Arthropoda are to be found in 

 notes on fossorial Hymenoptera by Turner (ibid.) and also in a 

 note on British fossil species of Woodlice, Apodemus, by Hinton 

 (ibid.). The holotype of Nymphon gracilipes, one of the Pycno- 

 gonida, is ably discussed by Caiman (ibid.). Couper's Snake in 

 the Zoological Society's Gardens has yielded a new mite de- 

 scribed by Hirst and placed in the genus Ichoronyssus, and it is 

 probably to be regarded as a primitive form since the female 

 markedly resembles the protonymph stage in other members 

 of the genus (Proc. Zool. Soc. May 191 5). The spiders collected 

 in Dutch New Guinea by recent expeditions, including a new 

 genus and new species, are recorded by Hogg (ibid.). 



Vertebrata. — Moodie has written an account of recent 

 studies in fossil Amphibia which provides a very useful resume 

 of practically all the work in this field for some years past, 

 together with a certain amount of criticism on it (American 

 Naturalist, June 191 5). Nichols has shown that in Anurous
