Zenaidura clarionensis. Towns. Pr. U. S. Nat. Mus. xiii. p. 133'; Salvad. Cat. Birds Brit. Mus. 



xxi. p. 378 ' ; Anthony, Auk, xv. p. 318 '. 



Z. caroUnensi similis, sed ubique saturatior : supra rufo-brunnescens, pileo postico vix cinerco tincto, et potins 

 dorso concolore : subtus omnino saturafciua vinaeea. Long, tota circa 10-5, alse 5-4, caudae 4-0, culm. 0-85, 

 tarsi 0-75. (Descr. maris adulti ex Clarion I. Mus. Brit.) 



ffab. Eevillagigedo Is., Clarion I. (Townsend ^ Anthony^). 



Mr. Anthony, who visited Clarion Island in 1897, says that this species was very 

 common there. He found a fully-fledged bird on May 19th, and on the 23rd a fresh 

 egg was found in a hollow in the ground, from which the parent fluttered upon being 

 approached. As Doves were often seen flying along the cliffs, and entering the holes 

 in the lava, it is not improbable that others were nesting there also ^. 



3. Zenaidura graysoni. 



Zenaidura graysoni, Lawr. Ann. Lye. N. Y. x. p. 17'; Mem. Best. Soc. N. H. ii. p. 304'; 

 Grayson, Pr. Bost. Soc. N. H. xiv. p. 299 ' ; Sal v. Ibis, 1874, p. 312 ' ; Towns. Pr. U. S. Nat. 

 Mus. xiii. p. 135 ° ; Salvad. Cat. Birds Brit. Mus. xxi. p. 378 ' ; Anthony, Auk, xv. p. 316 '. 



Z. earolinensi similis, sed corpore subtus toto rnfescenti-cinDamomeo distinguenda : rostro nigro ; pedibns et 

 iride rubris. Long, tota circa 11-0, aJae 5-8, caudse 4*8, culm. 0-65, tarsi 1-05. (Descr. ex scriptis 

 T. Salvadori.) 



Hah. Eevillagigedo Is., Socorro I. (Grayson^ ^, Townsend^, Anthony''). 



This species differs from Z. carolinensis and Z. clarionensis in the colour of the 

 under surface, which is entirely rufous-cinnamon. It is apparently a rare bird in 

 Socorro, but may be more abundant in the higher and less accessible parts of the 

 island. 



ZENAIDA. 



Zenaida, Bp. Comp. List Birds Eur. & N^. Amer. p. 41 (1838) ; Salvad. Cat. Birds Brit. Mus. 

 xxi. p. 379 (1893). 



This genus differs from Zenaidura in having a shorter and more rounded tail, the 

 latter being only three-fourths the length of the wing. The tail-feathers are fourteen 

 in number, as in Zenaidura, instead of twelve, as in Nesopelia of the Galapagos. 

 Zenaida is divided by Count Salvadori into two sections, one with, and the other 

 without, a band of white on the secondaries. The four species of the latter are 

 confined to South America, while the three white-banded forms inhabit respectively 

 the Greater and Lesser Antilles and the islands off the coast of Yucatan. 



Z. auriculata, a South-American species, distinguished by the absence of a white 

 wing-band and by the presence of white ends to the outer tail-feathers, has been 

 recorded from within our limits, as a specimen obtained by Kellett and Wood on the 

 Pearl Islands, off the coast of Panama, is referred to it by Count Salvadori (Cat. Birds 

 Brit. Mus. xxi. p. 386), but it is possible there may have been some error in the locality 

 recorded.
