ARTAMIA COMORENSIS 191 
the forests on the eastern slope of the highlands, where they 
may be seen frequently flitting from branch to branch on 
the tops of the highest trees in pursuit of their insect food; 
they generally congregate in parties of from fifteen to twenty, 
frequently uttering a little short cry, and are not shy. Their 
flight is rapid. They thrive well in captivity on insects, grain 
and cooked rice. In the north they are known as the 
‘Vorontsara-etra,’ and their Betsimisaraka name is ‘ Raisa- 
satra.’”’ The Rev. J. Sibree attributes the former name to 
A. chabert and adds “Fondra,” “ Pory” and “ Sarabesa”’ 
as North Sakalava names for this species. 
Pollen records the species as often found in flocks asso- 
ciating with other birds which frequent similar resorts.

Artamia comorensis, Shelley, Bull. B. O. C. iii. p. 42 (1894) Great 
Comoro Isl. ; id. B. Afr. i. No. 656 (1896) ; ii. pl. 2, fig. 1 (1900) ;

Type. Similar to the adult male of A. bicolor but larger, and with no 
black tip to the bill; upper parts of a more uniform and deeper cobalt blue 
faintly tinted with lilac. Total length 6:5 inches, culmen 0:8, wing 3°75, 
tail 2:7, tarsus 0°7. Great Comoro Island (Kirk). 
The Comoro Blue-and-white Vanga is confined to Great 
Comoro Island. 
The type, a beautiful adult specimen, figured in this work 
(ii. p. 41), was procured on the Island of Angaziya, or Great 
Comoro, and was presented to me by Sir John Kirk. Like 
some of the other species of this island it is a larger and 
finer representative of the Madagascar form. ‘To this species 
belongs a specimen obtained by M. Humblot, and referred 
to Cyanolanius bicolor by Milne Edwards and Oustalet in 1885.
