16th. A Long-tailed Duck was shot at Cley, and two Mer- 

 gansers (Pashley) ; and a few days later three more Mergansers. 

 A Pink-footed Goose with yellow legs was taken to Mr. Pashley 

 while fresh. Mr. Saunders says the Bean and Pink-footed Geese 

 have been known to hybridize in confinement, and doubtless they 

 sometimes cross in a wild state. M. Suchetet mentions several 

 hybrid Geese (' Oiseaux Hybrides,' p. 738). 



23rd. A cinnamon-coloured Yellowhammer at Yarmouth 

 (Patterson). 



24th. A Little Gull was caught alive during a gale at Lowestoft 

 (H. Bunn). 



26th. A Black-throated Diver was shot at Cley (Pashley). 



28th. A Waxwing at Filby (Lowne). 



ON WILD FOKMS OR SUB-SPECIES OF MUS MUSCULVS. 

 By G. E. H. Barrett- Hamilton. 



I was much interested in reading the remarks of Mr. Oldfield 

 Thomas (pp. 137-139), "On a Wild Living Mouse of the Mus 

 musculus group in Portugal," as last spring, while in Morocco, 

 I met with a white-bellied form of Mus musculus, which occurred 

 both about Tangier and also at Scharff-el-Akab, three or four 

 hours' journey southwards. I have four specimens of this mouse, 

 all males, in my collection, and their dimensions are as follows : — 



Length of head and body . . 83 80 81 80 mm. 



tail 57 59 53 56 „ 



hind foot ... 17 17 16 16 „ 



After carefully reading M. Fernand Lataste's description of 

 his Mus spretus* I am of opinion that my mice belong to this 

 species, although the line of demarcation between the colours of 

 the upper and under sides is more distinct in mine than it was in 

 his specimen, and although I cannot find that " sa premiere molaire 

 superieure presente un talon supplemental anterieur." Since, 

 however, Lataste based his species on a single specimen (a female 

 containing 4 + 5 = 9 young, and with the mammae as in Mus 

 musculus), from "l'Oued Magra, entre M'sila et Barika, au nord du 



:;: "Note sur les Souris d'Algerie et description d'une espece nouvelle 

 (Mus spretus)." Actes Soc. Linn. Bordeaux, torn, xxxvii. (1883).
