animals. Dr. J. Murie, the Society's Prosector, has made some 

 observations on the Tracheal Pouch of the Emeu (Dromoeus Novos 

 Hdllandife). He discussed the structure of this remarkable organ 

 and of the opening of the trachea into it, and made some sug- 

 gestions of its probable use in the bird's economy. The birds 

 added to the Society's menagerie have been from time to time noted 

 by the Secretary. Amongst others the various species of gulls, 

 and especially an example oiLarus fuscescens (Licht), from Mogador, 

 were remarked upon. Mr. Gould has described a new bird from 

 the interior of South Australia, which he proposes to call Malurus 

 callainus ; and other short ornithological papers have been laid 

 before the Society. No Keptiles appear to have engaged the 

 Society's attention during the quarter, but we have a few papers on 

 Fishes. Amongst these are those of Dr. F. Day, " On the Fishes 

 of the Neilgherry Hills and Kivers," and two by the same author 

 " On Fishes from Western India." 



New Mollusca from China have been described by Dr. Baird 

 and Mr. H. Adams, amongst which were some interesting forms of 

 Unionidae collected at Shanghai by Dr. J. Lamprey. 



The Coleoptera of the Azores have formed the subject of a 

 communication from Mr. G. E. Crotch, in which he has given an 

 account of a very fine collection of these insects formed by Mr. F. 

 Godnian during a recent visit to those islands. 



The interest in the beautiful Lace-sponge has been augmented 

 by a communication from Dr. Bowerbank on Eujplectella speciosum 

 (Owen), in which he gave a detailed account of the structure of this 

 organism. Dr. J. E. Gray has brought before the Society some 

 new genera of Sponges, and at the same time gave some notes upon 

 a new classification of the class.
