Type : ad., Banggai, Sula Islands. Native Coll. 



In 1900 we received a number of well-prepared skins, collected by natives, 

 from Mr. van Renesse van Duivenbode. They were said to come from Banggai in 

 the Sula group, east of Celebes. Though the localities of skins from this source 

 are often doubtful and incorrect, the locality must have been correct this time, 

 as shown by certain other species and subspecies. Among these skins were the 

 two specimens of Gazzola unicolor, and they remain all that is known to this day. 



The genus Gazzola is based on rather slight grounds, and is perhaps as well 

 united with Corvus. All that I can appreciate is the rather wide ridge of the 

 culmen, which is broadly devoid of bristles to the base, and the general thickness 

 of the beak. The tail is almost quite square. The shape of the wings affords 

 no reason for generic separation. 



14. Corvus corax hispanas Hart, and Kleinschm. = G. corax hispamts. 

 Corvus corax hispanua Hartert & Kleinschmidt, Nov. Zool. 1901, p. 45 (Spain. Type Aguilas). 

 Type : S ad., Aguilas near Murcia, shot from nest, 2. v. 1898. (3ray leg. 



15. Corvus corax canariensis Hart, and Kleinschm. 



Corvus corax canariensis Hartert & Kleinschmidt, Nov. Zool. 1901, p. 45 (Canary Islands. Type 

 from Falma). 



Type : cJ ad., Palma, Canary Islands. Scott Wilson leg. 



I admit that it is not easy to distinguish this form from G. c. tingitanus, 

 and that one might not agree to separate it, while no such questions can arise 

 with regard to C. chispdnus: Mf. Bannerman (Jbis, 1912, p. 625, 1914, p. 235) 

 declares that he does not find the supposed differences in his series, and he also 

 cites a letter from Otto le Roi, who said that he had come to the same conclusion. 

 At the same time I am not convinced that our conclusions are quite incorrect. 

 While there are specimens of canariensis which have the same beaks as tingitanus, 

 in the majority of examples the bill is slightly more elongated and not so high,
