Typical Pigeons. 145 



Triangular-spotted Pigeon (Columba guinea). 



Only sexed males are recorded in the Catalogue, but, according to 

 Salvadori, the female is similar to the male, though somewhat 

 smaller ; it is probable that the bill of the male is heavier when 

 seen in proBle. 



Naked-eyed Pigeon (Columba gymnophthalma). 

 Only one example in the Museum : but the same structural 

 differences — that is, in size and character of bill — should be looked 

 for as in most of the species of the genus. 



Picazuro Pigeon (Columba picazuro). 



Only males are indicated in the Museum Catalogue; therefore 

 look for the same structural differences. 



Spotted Pigeon (Columba maculosa). 

 The same note applies to this as to the preceding species. 



Olive Pigeon * (Columba' arquatrix). 



"Female. — Somewhat smaller and duller in colour than the 

 male; the vinous-purple colour of the neck more greyish" 

 (Salvadori, Catalogue of Birds, vol. xxi. p. 277). 



White-crowned Pigeon (Columba leucocephala). 

 According to Salvadori, the female is somewhat smaller and 

 duller than the male ; " the top of the head, at least in some 

 specimens, tinged with dirty grey." 



Porto Rico Pigeon (Columba squamosa). 



" Female. — Similar to the male, but somewhat smaller and perhaps 

 duller" (Salvadori, Catalogue oj Birds, vol. xxi. p. 281). 



Specious Pigeon (Columba speciosa). 

 "Female. — Differs from the male in being much duller, and 

 principally in having the back, rump, and smaller wing-coverts 

 brown, with no maroon colour" (Salvadori, Catalogue of Birds, vol. 

 xxi. p. 283). 



Cuban Pigeon (Columba inomata). 

 The female is smaller and duller in colouring than the male. 



Ring-tailed Pigeon (Columba eariboea). 

 The sexes have been stated to be alike, but Count Salvadori 

 seems doubtful of the accuracy of this assertion. Comparing sexes 

 in the Natural History Museum, I noted that the male was slightly 



* As the Zoological Society gives the same trivial name to this as to the pre- 

 ceding pigeon, I have adopted the name proposed in Stark and Sclater's Birds 

 of South Africa, vol. iv. p. 163.
