wishing to breed, a pair was selected and put together in a separate 

 enclosure. Here the eggs were laid, and the birds, as Mr. Selater 

 was assured, took turns in sitting ; but many of the eggs were 

 hatched in incubators. In one compartment were contained 11 

 examples (6 males and 5 females) of the very distinct Somali 

 Ostrich, Struthio molyhdoplianes. The remainder were all of the 

 typical northern form, S. camelus, -with red naked skin ; and 

 amongst them were many very fine birds, quite as large as the 

 well-known specimen lately in the Zoological Society's Grardens, 

 from Western Africa, deposited by the Queen. 



Mr. Howard Saunders, F.Z.S., exhibited, on behalf of Mr, E. M. 

 Barrington, a hybrid Duck shot in March last on the Moy Estuary, 

 in the West of Ireland. It was evidently a cross between the 

 Wigeon (Mareca penelope) and some other species ; the other 

 parent being supposed to have been the Gadwall {Clmulelasnms 

 streperus) b/ some authorities, while others inclined to the Pintail 

 {Dafila acuta), and others again to the Teal (Querqnedula crecca). 



Mr. Tegetmeier exhibited and made remarks on a specimen of 

 a Eook (Corvus frugiler/us), one of a number produced in one 

 Eookery, in which every feather of the entire plumage was tipped 

 or spangled with white. 



The following papers were read : —

Whilst describing a new Caecilian it has occurred to me that a 

 revised list of the 42 species of this order now known would prove 

 useful to the student of these interesting but stiU very imperfectly 

 known Batrachians. Since the publication of the last revision 

 (Cat. Batr. Grad. &c. 1882), in which 11 genera and 32 species 

 were defined, many new species have been described and numerous 

 additions and corrections have been made to the synonymy by 

 Cope, Boettger, Vaillant, Stejneger, and myself. These alterations 

 have all been worked into the list now offered for publication to 

 the Society. In order to facilitate identifications, synopses of the 

 genera and species have been inserted. The prefix of an asterisk 

 indicates that the species is represented in the British Museum,
