32 THE ZOOLOGIST. 



Mr. W. Hachett Jackson gave an abstract of an elaborate paper on the 

 external anatomical characters distinctive of sex in the chrysalis, and on 

 the development of the azygos oviduct, in Vanessa To. 



Mr. E. B. Poulton followed by giving a resume of his researches on the 

 external morphology of the lepidopterous pupa. Mr. J. H. Leech gave an 

 account of some new Lepidoptera from Central China. 



Dec. 5. — Mr. J. G. Baker, Vice-President, in the chair. 



The following were elected Fellows of the Society: — Rev. J.H. Crawford, 

 Major A. R. Dorward, Messrs. S. A. Moor, W. Rome, J. Shirley, H. L. 

 Stonham, C. W. Turner, J. T. Tristram Valentine, J. H. Veitch, J. J. 

 Walker, and John Watson. 



Mr. George Murray exhibited and made some remarks upon specimens 

 of Struvea macrophylla and S. plumosa. 



Mr. A. W. Bennett communicated some observations on a new and a 

 little-known British Freshwater Alga, Schizothrix anglica and Sphceroplaa 

 annulina. It was pointed out that Schizothrix of the ' Phycologia 

 Britannica' is really an Inactis. 



Mr. E. M. Holmes exhibited, as a new British Marine Alga, a speci 

 men of Gracillaria divergent, a rare native of the warmer portions of the 

 Atlantic and the Mediterranean, which had been recently found at Brighton 

 by Mr. J. Myles. The specimen exhibited possessed tetrasporic and 

 cystocarpic fruits not described by Agardh. 



Mr. Pascoe exhibited (with a view of eliciting information as to the 

 modus operandi) a number of Crustacea and certain shells of the genus 

 Phorus having various foreign substances attached to them. Commenting 

 upon these specimens, Prof. Stewart gave an interesting account, from 

 personal observation, of the way in which certain Crustacea collect and 

 adorn themselves with fragments of shell, sea-weed, &c, apparently as a 

 protective covering. 



Mr. T. Christy exhibited and made remarks on some "liquid amber,' 

 or resin, Attingia excelsa, from Cochin China. 



A paper was then read, by Mr. George Massee, on the life-history of a 

 stipitate Freshwater Alga, illustrated by some excellent diagrams. A 

 discussion followed in which the Chairman, Mr. Murray, and Mr. Bennett 

 took part. 



In the absence of the author, Mr. Harting detailed the chief points of 

 interest in a paper, by Mr. George Sim, on the anatomy of the Sand 

 Grouse, Syrrhaptes paradoxus, and the habits of this bird as observed on 

 the sand-hills of the coast of Aberdeenshire. A comparison was made of 

 the sternum and the alimentary organs with the same parts in the Pigeon 

 and Red Grouse.
