150 ANNALS OF SCOTTISH NATURAL HISTORY 



Scotland (Banffshire coast, T. Edward], and the south of 

 Norway. Prof. F. A. Smitt, in his " History of Scandinavian 

 Fishes" (1893), p. 55, writes of it as follows: "From its 

 proper home, the Mediterranean and the Atlantic between 

 the Canary Islands and England, the Black Sea-Bream has 

 several times wandered north and been met with on the 

 south coast of Norway, up to Trondhjem Fjord. On only 

 one single occasion, however, has it been found in Swedish 

 waters. ... It is extremely improbable that it propagates 

 its species north of England, as only full-grown specimens, 

 and never small fry, have been taken there. ... Its flesh is 

 generally little esteemed, but in the north of France it is 

 considered fairly good." 



The present specimen, it should be stated, has been 

 presented to the Royal Scottish Museum, Edinburgh. A 

 photograph of it, taken by my son, W. E. Evans, is here 

 reproduced. 



ON THE DIPTERA OF ST. KILDA. 



BY PERCY H. GRIMSHAW, F.E.S. 



I AM indebted to my friend the Rev. James Waterston, 

 B.D., B.Sc., for the privilege of examining a very fine 

 collection of Diptera made by him in the island of St. Kilda 

 during the months of June and July 1905. As considerably 

 over one thousand specimens were taken with discrimination 

 and carefully pinned by Mr. Waterston, it may fairly be claimed 

 that the present collection is a representative one, and that 

 the following list gives a tolerably good idea of the actual 

 Dipterous fauna of this small and remote, but none the less 

 interesting portion of the British Isles. Although I have 

 been able to clearly distinguish 119 species, yet a number 

 of these have baffled any attempt on my part to identify 

 them specifically. It is possible that some of those still 

 unnamed may be new to science, while the most interesting 

 of those satisfactorily determined include such species as 

 Diamesa tonsa, Hal. (probably never seen since the type 

 was described fifty years ago), RJiampJiouiyiafninipennis, Zett
