An adult, seemingly an aged male, is in Mr, Buxton's Lampong collection. That gentleman, 

 in his notes, describes the naked gular skin as bemg yellow, " with a black bar and greenish 

 tinge." This bar is evident on the dried skin. Dr. Cantor has described the gular pouch of 

 the Malaccan male as being " rich gamboge-yellow, with two transverse black bars " (Horsf. & 

 Moore, I. c.*), that of the female as dirty azure, with two transverse black bars," of the young 



* In his later account (I. c.) ilr. Moore omits all mention of tlie two transverse black bars.
