a series from Roma, Wetter, aud Letti, twentj-five specimens in all. They are 

 as puzzling as they can be. The majority from Roma aud Letti agree perfectly 

 with my nifomeriu^, but three from ^Vetter and some few from the other islands 

 have the second rectrix on the inner web almost entirely rufons-cinnamon or for 

 a great part of that colour. I wonld be willing to consider them more or less 

 immature, as they do not seem qnite adult (?), and there are intermediately 

 coloured ones between them and those looking exactly like ruj'onit'rns. But 

 there is one objection to this : our very young birds (without bars below) from 

 Dammer have no rufous at all or only a trace of it in the tail. What have we 

 now to conclnde? I think these birds with rufons in the tail must belong to 

 the same form as the adult ones looking like rufomen/s, because the markings 

 in the tail are absolutely the same ; they cannot well be poecilurus (which 

 Dr. Finsch records from Wetter), as that form has the outer rectrix differently 

 marked — at least, all those before me. Are these birds the same as those from 

 Dammer ? If not, we should have two forms only distinguishable by their young, 

 which is not probable I 



(a) Form from Dammer : above very dark, bars below somewhat wide, no 

 rufous in tail in adult and young : n/fomerxs. 



(b) Form from Roma (Wetter ?) and Letti : adnlt like that of r///omeriis, 

 younger birds with much rufons in the tail, first plumage not known. Probably 

 the same as the Dammer form. The Kisser bird (i/uiom/natus Finsch) might 

 belong to the Dammer one rather than to the Roma form ? 



(c) Form from the Malay Penmsula, Sumatra, Java, Borneo, Phili{ij)ines, and 

 Celebes : differs from (a) and (b) in the adult birds not losing the rufous in the 

 tail, bars below generally narrower : malayanus Raffl. 



(d) Form from North Australia, parts of New Guinea, etc., Aru, to Timor : 

 with a great amount of rufons-cinnamon in the tail, even the outermost rectrix 

 not without that colour : poccilwus. 



C. basalis is very different. It has much rufous iu the tail, is large and 

 pale, the middle of the abdomen unbarred. 



C. pla(/osus is also a large bird, but more widely barred below, with no rufous 

 in the tail. 



C. lucidus is merely a southern form of it and very much like the latter. 



Of the bird I now call C. rufomerus Mr. Kiihn sent the following specimens : — 



2 (?(?, Moa, 20, 31). xi. 19(»2. (Nos. (W.Vd, 63i)8.) These two birds are 

 like the adult Dammer birds, with wide bars below and hardly a shade of rufous 

 on the edges of the white patches on the second rectrix. 



3 (?c?, 1 ?, Moa, November, December 1902. (Nos. 6309, 031(), 6391, 6392.) 

 These four birds have narrower bars underneath and more or less, liut mostly, 

 a large amount of rufous in the tail. 



4 (?(?, Roma, August 1902. (Nos. 5334, 5354, 5368, 5368a). These birds 

 have no rufous at all in the tail. 



2 Si, 2 ? ?, Roma, August 1902. (Nos. 5029, 5332, 5333, 5335.) With 

 more or less (much to almost none) rufous-cinnamon in the tail, bars hardly 

 narrower. 



4 (?(?, Letti, December 1902. (Nos. 6431, 6433, 6435.) Without rufous in 

 the tail, bars below wide. 



1 S, Letti, 4. xi. 1902. (No. 5981.) Without rufous in the tail, but bars 

 narrower, upper wing-cpverts with pale edges (? immature). This specimen and
