Mr. L. DoxrASTER, M.A., F.Z.H., anrl the Rev. (!. H. Rayxok, 

 M.A., commimicated a paper on Breeding Experiments they had 

 made with Lepidoptera. 



The species used were Angerovajyrunaria and its xnv.sordiata, 

 and Abraxas grossidariata and its ver. lacticolor. 



In A. prunaria the banding of the vai-. sordiata Avas dominant 

 over its absence in the type, but the speckling characteristic of the 

 type appeared in the heterozygote, so that the latter was both 

 banded and speckled. The characters appeared to segregate in 

 the typical Mendelian manner, but in several families there was 

 an excess of jor?;7i«Wrt; ovei- sordiata. In A. grossidariata the 

 xnx. lacticolor was a Mendelian i-ecessive, but was noiinally found 

 only in the female. By pairing a heterozygous male with a 

 lacticolor female, lacticolor males and females wei'e obtained. 

 Lacticolor male X female gave only lacticolor ; lacticolor males 

 ])y heterozygote females had given all males of the type, all females 

 lacticolor. 



8evei'al typical families of each species were exhibited. 



Mr. W. P. Pycraft, F.Z.S.,read a paper on the " Tracheophone 

 Passeres," which lie desciibed as a group differing firm all the 

 remaining Passeres in the foimation of the syrinx, which was 

 tracheal — instead of tiacheo- bronchial — and jieculiar among 

 syringes of the ti'acheal type in the development of a cartila- 

 ginous pillai' for the inseition of the intrinsic niu.'-cles. The 

 group was divisible into three sections : («) having holorhinal 

 nares and a single-notched sternum, [h) with schizorhinal nares 

 and a single-notched sternum, and (c) with holorhinal nai'es and a 

 doubly-notched sternum . 



He proposed to make the Tracheophone Passeres one of four 

 gr-eat divisions of the Passerine stem. The most primitive of the 

 divisions Avould contain the Euiyjjvmida^, Cotingidte, and Phile- 

 pitta. The second would be represented by the Tracheophonse, 

 the third by the lyrannidfe and Pittidse, and the fourth by the 

 i-est of the Passeres. 



A paper by Messrs. Oldfield Thomas, F.R.S., and Harold 

 ScHWANX, F.Z.8., Avas read, giving an account of a collection of 

 Mammals made by Mr. C. H. B. Grant at Knysna,, and presented 

 to the National Museum l)y Mr. C. D. Rudd. The collection 

 consisted of about 150 specimens, belonging to 31 species or 

 subspecies, of Avhich the most noticeable Avas Mrs. Rudd's Golden 

 Mole {Amhh/somvs corrice), the description of Avhicli had already 

 been laid befoi'e the Society. 



A iieAv generic name, Xototragxs, Avas applied to the Grysbok, 

 Avhich diffei'ed from the other members of liaphicerios by its 

 possession of supplementary hoofs. 



A con an uni cation from Prof. Bashjord Dean contained an 

 account of 1he liabits of the Australian Lung-fish {Ccratodus 

 forainri) as obser\'ed l)y hiin in the Society's Menagerie.
