The male only differs from that of P. erythrogenys in being of a less yellowish green; the upper back and interscapulary tract are much bluer, and there is a bluish tinge on the breast. In females the mandibular stripe is green throughout. The size of P. tytleri is rather less.
Length of males 15.5 to 18.5, tail 9 to 10.5, wing 7 ; of females, length 15, tail 7, wing 6.75.
Distribution. The whole Andaman group, including Barren Island, Narcondam, the Cocos, and Preparis; common everywhere.
This and the last species are only just separable, but the distinctions, small as they are, appear to be quite constant.
P. longicauda, from the Malay Peninsula, Sumatra, and Borneo, is an allied species ; and a still more nearly related form is P. modesta, from Engano, off the S. W. coast of Sumatra.
