on Dr. JerdorPs e Birds of India’ 363 
208 and 209. Polyphasia nigra and P. tenuirostris. 
Barely separable, and included by Prof. Scblegel under 
Cuculus passerinus, Vabl, as distinguished from the Malayan 
C. merulinus (C. flavus, &c.). In the Malayan Peninsula P. 
tenuirostris occurs at Pinarig, and the smaller P. merulina at 
Malacca. 
214. Eudynamis orientalis. (Egg figured in Jard. Contrib. 
Orn. pi. 52.) 
All India with Ceylon, Indo-Chinese countries (including 
Siam and Cambogia), China, and Malayan Peninsula. In 
Sumatra [fide Bonaparte), Java, Philippines, Lombok, Elores, 
/ Timor, and Australia ( vide Ibis, 1865, p. 32), replaced by E. 
mindanensis (L.) (E. australis, Swain son, E. flindersi , Gould, 
B. Austr. iv. pi. 91), which is not the supposed E. flindersi of 
New Zealand referred to by Dr. Jerdon. Prof. Schlegel unites 
the Indian and Australian Coels, but I have always found them 
manifestly distinct, the Australian being considerably larger, 
with a greenish instead of a bluish gloss on the black male, and 
the nestling-plumage decidedly different. There is a fine series 
of both races in the Derby Museum at Liverpool. Length 
confidence in the opinion that the single specimen which I have called H. 
nisoides denotes a peculiar race, which should be sought for in Butan (as 
also Hierax melanoleucus, Alcedo grandis, Indicator xanthonotus, and other 
Sikhim rarities). There certainly is not that fusion of different races which 
we observe in the instances of the Indian and Indo-Chinese Rollers and in 
different specific races of Gallopliasis. 
The voice differs exceedingly in Cuculus canorus, C. striatus, and C. 
poliocephalus. That of Hierococcyx sparverioides is “ very similar ” to that 
of H. varius, and probably also of other specific races of this form. The 
vehement whistling cry of the Chok-galios or Hawk-Cuckoos is very 
peculiar among the group. I find that the voice of II. flaviventris is 
described in a note of Mr. Mottley’s (P. Z. S. 1863, p. 209 ):—“ A common 
bird, though rarely seen, from its habit of flying as it were on the upper 
side of a large branch to utter its monotonous cry. I have repeatedly 
tried in vain to discover it, when certainly a dozen must have been crying 
at once all around me! Its note is a loud but soft flute-like whistle, 
repeated three times, and then once again two notes lower, and is continued 
for several hours together in the evening.” This description certainly 
does not exactly apply to the whistling note of H. varius in India.
