NOTES ON THE VERTEBRATE FAUNA OF YORKSHIRE. 

 By W. Eagle Clarke, F.L.S., and W. Denison Rokbuck. 



It is our intention to prepare from time to time — annually if 

 possible — a report upon the vertebrate fauna of Yorkshire, in 

 which we propose to embody not only notices of the rarer and 

 more interesting occurrences in the county during the period 

 covered by the scope of the report, but also such records of 

 older date as may have escaped our attention during the com- 

 pilation of our ' Handbook of the Vertebrate Fauna of Yorkshire,' 

 together with such emendations and corrections of the statements 

 contained therein as may seem to be called for. 



The present report covers the period of time which has elapsed 

 since the publication of our Handbook in the autumn of 1881 

 down to the end of 1883, and includes notices concerning eighty- 

 seven species, of which the following nine appear to be additions 

 to the Yorkshire list : — Rhinoloplms hipposideros, Emberiza rustica, 

 Torpedo hebetans, Raja maculata, Auxis rochei, Trachypterus 

 arcticus, Regalecus grillii, Engraidis encrasicholus, and Ortha- 

 goriscus truncatus. 



In addition to these there are various occurrences to record 

 which are of special interest, such as those of Vespertilio Nattereri, 

 V. mystacinus, and Delphimis tursio among the Mammalia ; of 

 Ttirdus varius, Cyanecula sp. ?, Cypselus melba, Botaurus lenti- 

 ginosus, Ardea garzetta, and the breeding in the county of 

 Querqedula circia and Spatula clypeata among the Birds; and the 

 occurrence of Brama Rail, Mugil septentrionalis, Regalecus Banksii, 

 Ctenolabrus rupestris, Nerophis cequoreus, and Atherina presbyter 

 among the Fishes, 



The numerical summary of species now stands as follows, the 

 British forms being also given for comparison : —
