9. Myiobius subochraceus, sp. iiov. 



Supra sordide olivaceo-viridis, uropygio paulo magis ochraceo ; alls 

 nigrlcantibus, tectricum alariiim apicibus latis et secundariorum 

 marghiihus externis pallide fiilvis ; cauda obscure cinerea : subttis 

 late ochraceus, in rostro medio magis flavesceiis ; subalaribus 

 pallide ochraceis ; rostro obscure fusco ; pedibus niyris : long,

Obs. Affinis M. pulchro, sed crassitie majore et colore subtus 

 ochraceo diversus. 



The specimen described is apparently a female of a third species 

 of the group of 31. pulcher, distinguished by its large size and the 

 uniform ochraceous colouring below. There is just a faint appear- 

 ance of a bright colour on the crown, so that the male would 

 probably have a concealed orange crest. The bill is rather narrower 

 and more elongated than in M. bellus and M. pulcher. 



10. Empidonax ridgwayi, sp. nov. 



Supra obscure olivaceo-viridis, loris et oculorum atnbitu nlbescen- 

 tibus ; alis schistaceo-niyris, tectricum ularium apicibus et secun- 

 dariorum externorum marginibus externis albescentibus, ochraceo 

 vix tinctis ; cauda schistaceo-nigra ; hujus rectricis externce 

 poyonio externo albido ; infra sordide albus, in gula media clarior ; 

 ventre inferiore et crisso flavicante tinctis; subalaribus albis ;

Mr. Ridgway marks this bird, which has been submitted to his 

 examination, as " probably a new species, most like E. trailli in 

 coloration, but \Aith the outer web of the exterior rectrix white, as 

 in E. obscurus." I projiose to adopt this suggestion, which I quite 

 agree with, and to call the species Enipidotiax ridgwayi, after one 

 who has done so much good work in this group of birds. 



The second, third, and fourth primaries are nearly equal and 

 longest in this species. The first is shorter than the filth, and yery 

 slightly longer than the sixth.

Mr. F. Day, F.Z.S., exb.ibited a specimen of a hybrid Pilchard, and 

 a specimen oi Salmo j)ur])urutus raised in this country. 



A series of specimens of Lepidopterous Insects, which had been 

 bred in the Insect-house during the past season, was laid on the
