so perfectly resemble the adults, as in Megapodiua, I hesitate to sejjarate a form 

 on account of size onl}', unless I have measured a very large series. Local name : 

 " manuk kosong." 



2. Gallus varius (Shaw & Nodd.) 



Pliaxkinus rnriux Shaw & Nodder, Nut. Misc. X, pi. X>S, text (about 1799). (Loc. incert. — laccept 



Java as the typical locality.) 

 Gallu/i varius Vorderm., Natuurk. Tijiht-hr. Neil. furl. LII (1893) p. 204. 



(?(?Kangean East. "Iris brown; comb red, blue at base, throat-wattle red, 

 light and bright blue at lowest end ; feet greyish ; ujjper bill blackish, lower whitish." 

 ? 9 Kangean N.-E. "Iris yellow; feet greyish white, bill blackish, below white.'" 

 (Nos. 178, 179, 188, 225, 232.) 



Dr. Vorderman says that the Kangean fowls have lighter colours, and are more 

 easily tamed tlian those in Java. I find that the colours are exactly tlie same as in 

 Java cocks anil hens, while the dimensions and everything else also agree. Local 

 name: "ajam alas." 



Both Dr. Vorderman and Prillwitz (in litt.) tell us of the hybridisation of the 

 Gallus varius and the domestic fowl on Kangean. A cock of Gallics varius is made 

 lusty with a tame hen of Galius varius, which is half hidden in a hole in the ground, 

 and the natives cunningly substitute a domestic hen before the copulation begins. 

 The hybrid hens are killed; but the cocks, called "perkissar," are highly estimated 

 on account of their fine plumage and especially their frequent crowing, on which 

 the Malays bet, and whicli amuses them greatly. The offspring of the cock 

 perkissar and domestic hen is called " kapindu." It has also a fine plumage, but 

 does not crow so frequently, and is therefore not often bred. Pairs of cock perkissar 

 and hen perkissar, or of hen perkissar and domestic cock, as well as hen Oallns 

 varius and domestic cock, are said to be never fertile.

 (Nos. 65, 118.) Local name : " walik." 



The interesting form from Kangean differs conspicuously from the Ja\a form 

 (T. yriseicaiulu) by its much larger size, paler grey head and throat, brighter and 

 more yellowish green rump, lighter green underside, brighter maroon mantle in the 

 mate. It should, however, be compared with the form described by me as Osmotreron 

 wallacei palUdior,* from Djampea and Kalao Islands. It is most closely allied to the 

 latter subspecies, differing from it only in the slightly brighter green luidersurface 

 and gi-eyer, more sliarply separated throat. The throat in jjallidior is more whitish, 

 and the green merges into it. The under tail-coverts are apparently a little darker 

 cinnamon-brown in vordermani. T. g. vordermani differs also from griseicauda in 

 its tail, the black band being as sharply defined as in wallacei and pallidior. The 

 size is that oi jjaUidior. There is no doubt that these four forms and T. sangirensis 

 constitute a well-marked gioup of subspecies. They may be shortly diagnosed as 

 follows :
