The Juvenal female differs from the adult in its much more bronzy 

 interscapulum ; rudimentary hackles on the hind neck ; duller poste- 

 rior upper parts and wings ; much duller, more bronzy lower surface ; 

 and lack of hackles on the foreneck. 



Doctor Abbott reported having seen a few Nicobar pigeons on 

 Pulo Taya, but many more on the Nyamok Islets.

Columha grisea Bonnaterre 1790). 



A single adult female of this rare pigeon was obtained by Doctor 

 Abbott on Pulo Taya, July 27, 1899. The colors of the soft parts are 

 given as follows: "Iris pink; feet pale purple; bill greenish horny 

 at tip; base and cere dull brownish purple." Length in flesh, 

 406.5 mm. The plumage, both above and below, is somewhat adven- 

 titiously stained with brownish. 



Dr. Charles W. Eichmond some time ago called attention to the 

 preoccupation of the name Columla grisea as used for this species, 

 and proposed Columba "phasma in its place.^ Unfortunately, how- 

 ever, the term Columha argentina (a manuscript name from Tem- 

 minck), inserted tentatively by Bonaparte as a synonym of his 

 Myristicivora grisea^ becomes thus a substitute name for the latter. 

 Since, therefore, the specific name grisea can not be used in the 

 genus Columha^ on account of the previous Columba grisea Bonna- 

 terre,^ for a South American species of Chaemepelia^ the bird here- 

 tofore called Columba grisea (Bonaparte) must now be known as 

 Columba argentina Bonaparte. 



This species was first named Carpophaga grisea by G. R. Gray,* 

 from a specimen in the British Museum collected in the " Indian 

 Archipelago." This example is now j^reserved in the British 

 Museum, and should be considered, as already done by Count 

 Salvadori,^ the type of Bonaparte's name MyHsticivora gri^^ea^ and 

 hence of the species, since both the two other names applied to this 

 pigeon, Colu7iiba argentina Bonaparte and Columba phasma Rich- 

 mond, must be treated as merely substitute terms. The type-locality 

 of the species is consequently the Indian Archipelago.
