THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 151 



1 Nepalese Eagle-Owl {Hithua nipalensis), from the Maikola 

 A^allej, East Nepal, purchased on December 4th. 



1 Jiu.shm.-Aster {Lachesis muhts), from Trinidad, presented by 

 the Baron Leijonhufvud, F.Z.S., on December 10th. 



Mr. D, Seth-Smith, F.Z.S., Curator of Birds, exhibited a 

 female Carolina Duck {^Lampi'onessa sponsa) which had partially 

 assumed the male plumage. It had shown no sign of this con- 

 dition before the last moult. It now resembled the male in most 

 respects, although the colours were duller and the characteristic 

 markings less clearly defined, but it retained the brown colouring 

 of the eye and the yellow skin and white patch of feathers sur- 

 rounding it, which were characters of the female. 



Mr. E. G. BouLENGER, F.Z.S., Curator of Reptiles, exhibited a 

 blue specimen of the Edible Frog {Bana esculenta) which he had 

 obtained from Tuscany. The blue colour was attributed to the 

 absence of yellow pigment, which is present in large quantities 

 in green frogs. This aberration is not very unfrequent in the 

 European Tree-Frog [ffyla arborea), but very rare in the Edible 

 Frog, and this was the first occasion on which such a specimen 

 had been exhibited in the Gardens. Blue Edible Frogs have 

 been previously reported from France, Western Germany, and 

 Switzerland. 



Mr. BouiiENGER also exhibited a living specimen of the remark- 

 able Lizard Pygopus lepidopus, a species which is rarely seen 

 alive in this country, and which had not been represented in the 

 Society's Collection for some considerable time. 



February 18, 1913.
