the bights. New and old foot-prints in the loam were to be seen on 

 the land near the fresh-water puddles, and, as this was the case 

 even up to the end of July, one may correctly assume that this 

 Diver breeds on Jan Mayen. A female bird shot on the 29th of 

 June was in full breeding plumage. 



Colymbus septentrionalis, L., Red-throated Diver. — I saw this 

 Diver singly and in pairs, in autumn, in the north lagoons. We 

 also heard now and then the call of this bird (reminding one of 

 a human wail) as it flew across the island at a great height. We 

 could not get at one. The continued residence of the same in 

 and near the north lagoon, in a chosen hidden corner, favours 

 the conclusion that this Diver breeds on Jan Mayen. At last 

 I shot one flying across the lagoon. The specimen brought 

 home was obtained on the 10th of June, and proved to be a 

 female in full summer plumage. 



Podiceps arcticus, Boie = Podiceps cornutus, Gm., Sclavonian 

 Grebe. — I saw a single specimen on the 23rd of June, which I 

 shot. Female * * * [description], [This bird is a common 

 summer visitor to Iceland, but only occasionally occurs in Green- 

 land ; its occurrence on Jan Mayen Island is believed to be the 

 most northerly on record. — W. E. C]

NOTES AND QUERIES, 



MAMMALIA. 



Cat with Eyes of different Colours.— There is at the present time in 

 this village a full-grown white Cat which has eyes of different colours. 

 The iris of one is of the ordinary pale greenish yellow, while that of the 

 other is of a beautiful pale, but bright and pure, cobalt-blue.— 0. V. Aplin 

 (Bloxhara, Oxou). [White cats with blue eyes are nearly always deaf. — Ed.] 



Variety of the Field Vole.— A curious variety of the Short-tailed 

 Field Vole {Arvicola agrestis) was captured last month in this neighbour- 

 hood. The head and back are sand-coloured (like a sandy rabbit), this 

 colour shading of! into nearly white on the under parts. — 0. V. Aplin 

 (Bloxharn, Oxou).
