and greater than in so-called G. layardi of Central and Southern 

 India and Ceylon. Of the specific distinction of the last- 

 named species I am not yet quite satisfied, the question 

 mainly turning upon whether the adult male (and female ?) 

 always has the upper part of the abdominal region barred 

 instead of pure white.

" S. Andaman : § , iris lake ; bill and feet black." 

 An excellent species ; perfectly distinct from G. concretus, 

 Hartl., and G. striatus (Bodd) . The example, sent as a female, 

 has the entire under plumage barred across. A second in- 

 dividual, not sexed, has the chin, throat, and upper breast 

 uniform plumbeous. Seen from below it recalls the beautiful 

 G.lineatus (Swains.) = G.swainsoni, Gould; but the dark bands 

 are not as decided and well defined, nor so intensely black as 

 in the Australian species. In all other characters it entirely 

 differs.

" S. Andaman, Jan. 3, $ ; 18, $ ." 



Two examples of a female Arachnechthra are in Mr. Barn- 

 say's collection, but unfortunately no males. Provisionally 

 I refer them to the well-known Burman species, as Mr. Ball's 

 description (/. c.) of the male agrees best with that Sunbird. 

 That gentleman states that in all the male specimens " there 

 are more or less distinct traces of a maroon pectoral band/' 

 which character is at' once decisive against their belonging to 

 A. frenata. With Tenasserim examples of A. flammaxil- 

 laris $ these Andaman individuals fairly agree.
