Show 1877.] DR. F. DAY ON COREGONUS OXYRHYNCHUS. 419 Spix obtained his specimen at Tabatinga; Mr. E. Bartlett got a single example on the Huallaga1; and Castelnau and Deville brought home a series a from the Upper Amazons, but do not give the exact locality. 4. Two specimens of the rare Yellow-throated Parrot, Caica xan-thomera (G. R. Gray), which arrived along with the Pygmy Marmoset, also quite new to the collection. Mr. Sclater made some remarks on the progress and condition of the Zoological Gardens of Rotterdam, Amsterdam, Antwerp, Brussels, and Ghent, which he had lately visited. In Rotterdam he had seen a pair of the West-African Jackal described and figured in the Society's 'Proceedings' (1870, p. 279, pl. xxiii.) as Canis lateralis, and a fine specimen of Casuarius uniappendiculatus. At Amsterdam Mr. Sclater had found the young male Hippopotamus, born on the 3rd of August, 1876, in excellent health and condition, and another young one expected shortly. Two examples, nearly adult, of Casuarius uniappendiculatus were in the collection, one of which Mr. Westerman has consented to part with to this Society. At Antwerp M . Vekemans was busy on the construction of a new Lion-house, about 230 ft. long by 65 ft.-that is, of about the same dimensions as the Society's newly-constructed building. A communication was read from Dr. G. S. Brady, C.M.Z.S., containing a memoir on the Fossil Ostracoda of the Antwerp Crag. This paper will be published in the Society's ' Transactions.' The following papers were read :- 1. Notice of the Capture of Coregonus oxyrhynchus in Lincolnshire. By F R A N C I S D A Y , F.Z.S. [Received May 7, 1877.] Amongst a consignment of fresh fish received on April 1 7th, this year, at Cheltenham, from Lincolnshire, I observed a Coregonus3, along with some Smelts (Osmerus eperlanus). So far as I am aware, Coregonus oxyrhynchus has not been previously recorded as either a visitor to or resident along the coasts of Great Britain or Ireland. The genus Coregonus has been divided into those forms having (a) The lower jaw the longer, (b) The upper jaw the longer. Amongst those comprising this latter division, a soft prolongation of the snout may be present or absent. 1 See P. Z. S. 1871, p. 220. , 2 See Casteln. and Dev., Exp. de l'Am. d. S.
