George Busk, Esq., F.R.S., V.P., in the Chair. 



The Secretary called attention to two fine specimens of Boidce 

 lately added to the Society's collection of living Reptiles, namely: — 



1. A specimen of the Carpet-Snake of Australia {Morelia varie- 

 gata. Gray), received from Queensland, purchased of a dealer. 



2. A specimen of the Peruvian Boa (JBoa eques, Eyd. et Soul.), 

 from Guayaquil, presented to the Society by Prof. William Nation, 

 of Lima, Peru, C.M.Z.S. 



Mr. Sclater also called attention to the specimen of Larus fusces- 

 cens, Licht. (Clupeilarus fuscescens, Bp. Consp. ii. p. 221), living 

 in the Society's Gardens, having been purchased, when in immature 

 plumage, in 18.59, out of a vessel coming from Mogador, and pointed 

 out how very distinct, when seen alive and in full plumage, this bird 

 was from its near allies Larus fiiscus and Larus argentatus. The 

 three species might be diagnosed as follows : — 



L. argentatus. Major ; pedibus pallide carneis : chlamyde ci- 



L. fuscescens. Medius : pedibus Isete flavis : chlamyde nigricanti- 

 cinerea. 



L. fuscus. Minor : pedibus pallide flavis : chlamyde nigricante.
