58 VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 
seventh quill, if any thing, the longest. The claw of the hallux is short, and therefore 
appears straight; in character, it is the claw of the large species, shortened in pro- 
portion to the size of the bird. In the second and third groups the hind claws are 
not proportionately diminished, and therefore appear disproportionate when compared 
with those of the large species. The upper surface of the tail is a deep, rich, almost 
purple blue. The nape is glossy violet-blue, contrasting with the duller green-black of 
the head. The adolescent plumage possesses characters peculiar to the species. From 
this it will be seen that it has no characters in common with the members of the second 
and third groups. It does not appear to be contained in the Leyden Museum. 
The following is a synopsis of the smaller Asiatic Coucals, together with the dimen- 
sions of the individuals I have had access to. Cuculus tolu, Gm., ex Madagascar, seems 
to belong to the Asiatic and not to the African section of Centropodine. 
A. 
1. Centrococcyx affinis (Horsf.), Trans. Linn. Soc. xiii. p. 180, “ Java” (1821). 
Cuculus totu, Gm., ap. Raffles, Trans. Linn. Soe. xiii. p. 285, is either the Sumatran form of this 
species or else of C. javanensis. 
Hab. Sava, Sumatra (2), Celebes, Flores. 
2. Centrococcyx medius (Bp.), ex Miiller, Consp. i. p. 108, ““ Amboyna” (1850). 
Professor Schlegel applies this title to the Amboyna species. Prince Bonaparte 
includes the Javan form. 
Hab. Amboyna, Ceram. 
B. 
1. Centrococcyx javanensis (Dumont de Ste. Croix): Dict. Sc. Nat. xi. p. 144, “Java” 
(1818). 
Centropus lepidus, Horsf. Trans. Linn. Soe. xiii. p. 180, “ Java” (1821). 
Centropus pumilus, Less. Traité, p. 136, “ Java” (1831). 
Lesson described partly from the example on which Dumont founded the title of 
javanensis. My Bornean example is smaller than Javan individuals. 
Hab, Java, Malacca, Banjermassing, Celebes. 
2. Centrococcyx viridis (Scop.), Del. Fl. Faun. Insub. ii. p. 89 (1786), “ Philippines,” 
ex Sonn. 
Centropus philippensis, Cuv. R. An. i. p. 426 (1817), ex Pl. Enl. 824, “ Philippines.” 
Corydonix pyrrhopterus, Vieill. Enc. Method. iii. p. 1353, ex Pl. Enl. 824, “ Philippines” (1823). 
Centropus molkenboeri, Bp. Consp. i. p. 108, descr. orig. (1850), “ Philippines.” 
In the first edition of the Régn. An., Cuvier erroneously quotes Pl. Enl. 884. In the 
edition of 1829 this error is corrected. Vieillot founded his species on Pl. Enl. 225—also
