1919-] Birds of the Canary Islands. 99 



Systematic List of Species. 



Family Cokwum. 

 Corvus corax. Raven. 

 A Resident species. 

 Habitat in Archipelago . 



Western Group : Tenerife, Gran Canaria, Palma, Goraera, 



Hierro. 

 Eastern Group : Fuerteventura^ Lanzarote. 

 Outer islets : Allegranza, Montana Clara. 

 Obs. I have not yet decided whether the Canarian Raven 

 is distinct from the form found on the mainland. The 

 Canarian bird has been named Corvus corax canariensis 

 Hartert & Kleinschm. (Nov. Zool. 1901, p. 45 — Type 

 locality : Palma). The African species to which I have 

 hitherto united it is Corvus corax tingitanus Lvhy (Ii)i.s, 1874, 

 p. 261 — Type locality : Tangier, Morocco). 

 Range beyond the Archipelago. 

 C. c. canariensis does not occur. 



C. c. tingitanus : Tunis to Morocco south west to 

 Mogador and Casablanca. 



Corvus monedula spermologus. West European Jackdaw. 



Corvus spermologus Vieillot, Nouv. Diet. d'Hist. Nat. viii. 

 1817, p. -10 — Type locality : south of France. 



A very Rare Visitor to these islands, which are far beyond 

 the usual range of this species. The form w'hich is here 

 dealt with is doubtless Corvus monedula spermologus if 

 recognized as distinct from C. m. monedula. 



The Jackdaw has only been recorded once, by Webb & 

 Berthelot who wrote (Orn. Canarienne, p. 10) that a single 

 specimen o^ Corvus monedula was killed at Laguna (Tenerife) 

 after a very strong south-east gale in February 1830, the 

 only one (as they mention) seen in ten years. 



Bolle also mentions this bird in his first list (J. f. O. 1854, 

 p. 451).
