of the Genus Haplopelia. 13 



unable to examine this Pigeon personally, but Count Salva- 

 dori describes it so minutely that I have been able to place 

 it exactly, and include it in my key to the species. The 

 following is a translation of Count Salvadori's latin 

 description : — 



S ad. Forehead white, gradually shading into grey on 

 the occiput ; hind-neck and interscapular region grey ; the 

 margins of many of the feathers green or shining ame- 

 thystine. Back, rump, wing-coverts, and middle upper tail- 

 coverts brownish-grey. Throat white, forepart and sides of 

 the neck becoming green when held in certain lights. 

 Middle of the belly and under tail-coverts white; sides of 

 the body grey. Greater wing-coverts, lateral upper tail- 

 coverts, and middle pair of tail-feathers lead-colour ; 

 remaining tail-feathers greenish-plumbeous above, pale grey 

 towards the tip. Underside of the tail black, with a broad 

 apical band of whitish-grey. Remiges brownish-grey ; 

 under wing-coverts plumbeous. Bill black. 



Total length about 290 mm.; wing 150; tail 92; culmenl2; 

 tarsus 30. 



The above description applies equally well to the male 

 bird of H. s. inornata, H. s. plumbescemt , or H. s. poensis ! 

 As, however, these races differ only very slightly in the 

 females, I have upheld the name proposed for the Annobon 

 bird. It may well prove to have a female showing differences 

 from the three forms mentioned above, and, being isolated, 

 is all the more likely to be distinct. It must be a very rare 

 bird on Annobon, as Boyd Alexander did not secure a single 

 specimen during his last visit to the island. 



Could it have been a chance wanderer from the mainland ? 

 As it is known to the natives by the name of " Lola 

 Siin-San,^' this is not very probable. Fea, however, says it 

 is extremely rare.
