and the yonug typical alhcrtisii (? ami females) having a slaty throat and 

 being darker and clouded with grey underneath, these Batjan specimens closely 

 resemlile young tyjiical albertisii. The young C. alhertiui albi'rtisii, however, 

 have a niCous forehead, which is only to be seen in one of the Batjan specimens. 

 Nevertheless, the fresh sprouting feathers on the upper throat being dark slate, 

 I am convinced that they are always, throughout all ages, slate-coloured. The 

 wings also are very long, though partly in moult, aud the crown and hindneck to 

 the iuterscapulium are conspicuously darker. Wings 216 — 220 mm. The greater 

 size is the more remarkable, as we have probably no adult male yet from Batjan, 

 sxiAfemales of typical albevtim are smaller than males. 



One of the Batjan examples is marked as having been shot 30U(i ft. above the 

 sea. The others have no elevation marked on the labels, and should therefore, if 

 the labelling is done with care, have come from the lowlands. 



The island of Batjan is, of course, (j^uite out of the range of ('olamha 

 {GymHophaps) albertisii, which is only known from New Guinea (Papua) itself. 

 Therefore (unless we believe that it has been introduced by Malays) the entirely 

 new habitat alone should suggest that the Batjan race is different. In view of the 

 occurrence of Columba mada Hart, on Burn (cf. Bull. B. 0. Club viii. p. 33 and 

 Nov. ZooL. 1900. p. 241), the existence of another Colamba still nearer albertisii on 

 the Moluccas is not quite so surprising.

(It is incomprehensible to me that the name albigularis, published without au 

 attempt at a descrijition, could become generally accepted for this pigeon. In the 

 t'onsp. Ac. p. 44, Bonaparte names this bird J. halnmheiru, aud gives a sufficient 

 diagnosis, mentioning that it is the Carpophaga albigularis Temm. nee Gray {sic)
