VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 111 
the character of the banding on the middle rectrices of the immature male. But in the 
immature female there is no terminal dark brown band, and the middle rectrices are 
almost evenly divided by seven pale and seven dark-brown bands. Yet in all other 
respects the immature pair are identical in plumage. 
PERNIS CELEBENSIS. 
Pernis ptilorhyncha (Temm.), anted, p. 36. 
An examination of several examples of the Celebean Honey-Buzzard has convinced 
me that it is distinct from the Indian and Javan species. In this view I am only con- 
curring with both Messrs. Gurney and Wallace, and therefore propose the above title 
for it. The remarkable resemblance of this species to Limnaétus lanceolatus, in adult 
plumage, has been commented on by Mr. Wallace and Professor Schlegel. 
Upper surface brown. Chin, throat, and cheeks white, each feather broadly centred 
with dark brown. Breast pale rufous, some of the feathers with brown central stripes. 
Abdominal and ventral region, flanks, under wing- and tail-coverts, and the thigh-coverts 
white, with two, three, or four broad transverse bands. Tail crossed by three broad 
dark-brown bands, one being terminal; between the terminal band and the next a 
broad, light greyish-brown band of irregular shading and marking ; between the second. 
dark-brown band and the third a paler brown band. 
YUNGIPICUS TEMMINCKI (Malherbe), anted, p. 41. 
Dr. Meyer has sent a male as well as several females of this rare species. The male, 
hitherto unknown, is peculiar in having the sides of the neck blood-red instead of a 
narrow stripe behind the eyes. In other respects it exactly resembles the female. 
Notwithstanding Bonaparte’s remark (Consp. i. p. 137, no. 20), this species in no way 
resembles Y. kisuki. It is an isolated form, readily distinguished by its olive-brown 
plumage, spotted on the wings with yellowish-white dots, by its fulvous upper tail- 
coverts and rump, and by all its rectrices being barred rufous and brown. 
MEROPOGON FORSTENI (Temm.), anted, p. 42. 
This species has the first primary half the length of the second, which is a little 
shorter than the third. The third and fourth are longest, and equal. The fifth is 
somewhat shorter than the third and fourth, but longer than the second. In the 
structure of the wing, therefore, it differs from both Merops and Melittophagus', but 
agrees with Nyctiornis. The grooved culmen of Nyctiornis is not present; but a shallow 
channel extends from the base of the maxilla, on both sides of the culmen, for two 
* Prince Bonaparte says (Consp. i. p. 164), “ale Melittophagi;” but in Melittophagus, M. minutus being the 
type, the third quill is the longest. The African species which most resembles MW. forsteni in the graduation of 
the quills and the form of the rectrices, the middle pair excepted, is M. bullockoides, Smith.
