MAMMALS 



in each case (this has certainly been the experience of the writer), and 

 might also reveal some unlooked-for facts as to their frequency or other- 

 wise and the periods of their occurrence, for experience indicates that 

 some species are as constant in their migratory movements as the re- 

 cognized birds of passage, and pass along our coast with the same 

 unerring regularity. It is not unlikely that the bottle-nose dolphin 

 (£). tursio) visits the Norfolk waters at certain seasons, but I know of no 

 instance of its capture, nor have I hitherto been able to record the 

 occurrence of the common dolphin (Z). delphis), which latter seemed to 

 be well known to Sir Thomas Browne. 



Another family in which there is scope for further investigation is 

 that of the Cheiroptera. It is probable that a closer study of these animals 

 would be rewarded by the addition of two or three species at present not 

 recognized as occurring in Norfolk ; the serotine, hairy-armed bat, 

 Daubenton's and the whiskered bat should be looked for. 



I make no apology for these brief remarks, for it is often as in- 

 teresting and instructive to a faunist to know what species, which might 

 reasonably be expected to occur, are missing from a certain district as it 

 is to know those which are actually met with. 



The chief authorities on the Mammals of Norfolk are Messrs. C. J. 

 and James Paget, who published a list in their Sketch of the Natural 

 History of Great Yarmouth, in 1834 ; the Rev. Richard Lubbock in his 

 Observations on the Fauna of Norfolk, 1845 (2nd edit., 1879) and many 

 scattered records in the pages of the Zoologist. The present writer has 

 also contributed a list to the Norfolk and Norwich Naturalists' Society, 

 which, with Supplements, will be found in their 'Transactions, vol. i. 

 (1870-71) p. 71 ; vol. iii. p. 657 ; vol. v. p. 632 ; and vol. vi. p. 493. 

 Other references will be found in the notes which follow. 



Of the forty-five species recorded we have the monopoly of at least 

 four. 



CHEIROPTERA
