118 THE ZOOLOGIST. 



Mr. Thomas Christy exhibited and made remarks on some specimens of 

 honey: — (1), "Arbutus honey," from Turkey, said to produce great drowsi- 

 ness and sleep; (2) " Eucalyptus honey," from Mount Barker, Adelaide, 

 said to possess valuable therapeutic properties; and (3) so-called "Wool 

 honey," from the Euphrates, collected by natives from the leaves of the 

 oak, which would be more properly termed " honey-dew," being formed by 

 aphides, and not by bees. 



Mr. J. E. Harting exhibited a living albino example of the Common 

 Frog, Rana temporaria, captured in Wiltshire in September last, and 

 remarked upon the infrequency of albinism amongst the Batrachia and 

 Keptilia, of which he had only been able to find four or five recorded 

 instances. 



On behalf of Mr. Gammie, of Sikira, Mr. C. B. Clarke gave an 

 abstract of an interesting paper on the Tree Ferns of Slkim, in which 

 several moot points were discussed and difficulties cleared up. 



The next paper was one by Prof. W. A. Herdman, on a revised classifi- 

 cation of the Tunicata. Taking as a basis the scheme of classification 

 adopted in his Report on the ' Challenger ' collection, he incorporated the 

 various known genera and species not represented in this collection, and 

 discussed the general principles to be recognised in classifying the Tunicata, 

 especially dwelling on the value of the various modifications of the branchial 

 sac, and of the tentacles. The polyphyletic origin of the group Ascidia 

 composite was pointed out, and the relations between simple and compound 

 Ascidians were shown by means of a phylogenetic diagram. 



A paper was then read by Prof. G. B. Howes, in which he gave a 

 description of the genitalia of six hermaphroditic Codfish examined by him, 

 and a resume of what is known on the general subject of hermaphroditism 

 amongst fishes, more particularly referring to the Teleostei, which exhibited 

 the most nearly primitive condition of the genital gland realised by living 

 Vertebrata. He regarded the genital duct of the Teleostei as homologous 

 in both sexes, representing a primitively hermaphrodite duct of the 

 ancestral chordata. He sought to homologise it with the proliferating 

 mass described by Balfour and Sedgwick, Furbinger, and others, as entering 

 into the formation of the base of the Mullerian duct proper, and regarded 

 it as having been replaced by that structure on the advent of uni-sexuality. 

 Several other points were touched upon of special interest to physiologists.
