4. carolinensi similis, sed ubique saturatior : supra rufo-brunnescens, pileo postico vix cinereo tincto, et potius 
dorso concolore : subtus omnino saturatius vinacea. Long. tota circa 10°5, ale 5:4, caude 4-0, culm. 0°85, 
tarsi 0°75. (Descr. maris adulti ex Clarion I. Mus, Brit.)

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 °.

Z. carolinensi similis, sed corpore subtus toto rufescenti-cinnamomeo distinguenda: rostro nigro; pedibus et 
iride rubris. Long. tota circa 11:0, ale 5°8, caude 4°8, culm. 0°65, tarsi 1:05. (Deser. ex seriptis

Hab. Revittacicepo Is., Socorro I. (Grayson1?, Townsend 5, 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. 879 (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.
