142 Lord Walden on a further Collection of 
any kind of description; and their accounts, unsatisfactory 
and meagre, relate to the Bengal bird. But Mr. Blyth has 
recorded the identity of his T. grisola with Javan, Pinang, 
Arakan, and Andaman examples, while Dr. Cabanis, having 
compared the S.E. Bornean example alluded to by Mr. 
Sclater (/. c.), identified it with Javan examples of Hyloterpe 
philomela (Boie), Temm., in the Berlin museum. This Bor¬ 
nean individual agrees well with several Javan examples, as 
well as with one from Malacca in my collection. In it the 
entire head above is ashy brown, the rest of the upper sur¬ 
face of the bird being of a ruddy brown. The throat, cheeks, 
flanks, abdominal and ventral region silky white slightly 
sullied on the throat and cheeks with the cinereous hue 
of the breast, there forming a distinctive band. The bill 
is black. A single Javan specimen differs materially from 
the remainder by having the head, cheeks, ear-coverts, back, 
and uropygium uniform dark ferruginous asji-colour with¬ 
out a tinge of rufous brown, and by the throat and breast 
being almost uniform in their shade of dark smoky ash-colour, 
though lighter than above. Neither in structure nor in di¬ 
mensions can this bird be distinguished from the others; 
and I must therefore regard it as a sexual or other stage 
of plumage. Three other Javan individuals differ from the 
Bornean type by having pale yellowish bills, by the upper 
surface of their plumage being of a much redder and lighter 
hue, and by the outer edgings of the quills being bright 
rufous. These may be young birds. Be that as it may, 
three very distinct phases of plumage are represented in my 
Javan series. 
The three Andaman specimens obtained by Mr. W. Bams ay 
have the head above and nape smoky ash-colour, very much 
like the single Javan bird described above; but the cheeks and 
ear-coverts are pale grey, nearly white, and not fuliginous. 
The dorsal plumage has more an olive than a ruddy tinge, 
and is not fuliginous. Underneath, the colouring agrees with 
the Bornean bird. These Andaman examples therefore re¬ 
present a fourth phase of plumage; for I am disinclined, with¬ 
out more acquaintance with the group, and after Mr. Blyth's
