2 (?) xEgialttis dealbata, Swinh. Proc. Zool. See. Lend. 1870, 138 (southern coast of China, 



including Formosa and Hainan). 

 To this bird I refer, with much hesitation, five specimens of an ^'Eglulitis from Hong-Kong Bay, col- 

 lected by Mr. P. L. Jouy, of tlie United States Xational Museum. These birds, while closely resembling 

 ^. alexandrina (vel cantiana), are uniformly much larger than European examples of the latter, as 

 indicated by the measurements given above ; they are likewise nmch more richly colored, an adult male 

 collected November 12, and an adult female olrtained about the .same time, having the entire crown and 

 occijjut a soft cimianion-buff or light cinnamon-rufous, the female having even the whole dorsal region, 

 including the tertials, tinged with this color.
