The dimensions of the four Andaman individuals in the collection are less than those of 

 G, macei from Northern India, about equal with those of the same species from Burma, and 

 greater than in so-called G. layardi of Central and Southern India and Ceylon. Of the specific Ibis, 1873, 

 distinction of the last-named species I am not yet quite satisfied, the question mainly turning 

 upon whether the adult male (and female X) 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 individual 

 not sexed, has the chin, throat, and upper breast uniform plumbeous. Seen from below it recalls 

 the beautiful G. lineatus (Swains. )=rT. mvainsoni, 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.

Two female examples of an Arachnechthra are in Mr. Ramsay's collection, but unfortunately 

 no males. Provisionally I refer them to the well-known Burmese species, as Mr. Ball's description 

 (/. c.) of the male agrees best with that Sun-bird. 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. flammaccillaris $ these Andaman individuals fairly agree.
