1. Trei-on* griaeicauda griseicauda : Rather smaller (wing of males about 

 145 to 153 mm.), duller and darker, mantle deeper red-brown, tail-feathers seen 

 from above with an ill-defined band across the middle. Hab. Java, Bali (and 

 Lombok ?) ; males from the latter island, however, not examined, the fenutle slightly 

 lighter than Java females). 



2. Treron griseicauda tvallacei : Closely allied to t^i^ical griseicauda and of 

 the same size, but colour generally brighter and lighter, the dull orange patch on the 

 sides of the neck larger, the band across the rectrices very sharply defined. Wing of 

 laalea 144 to 153 mm. Hab. Celebes and Sula Islands. 



3. Treron griseicauda sangirensis: Only larger, wing longer (in males 150 to 

 160 mm.), and with a somewhat more robust bill, otherwise like T. g. wallacei. Hab. 

 Sanghi Islands. 



4. Trermi griseicauda pallidior: jNIueh more distinct from Nos. 1, 2, and 3, than 

 any of the former from each other, being much paler, lighter, and generally larger. 

 Tail as in Nos. 2 and 3. Wing in males, 162 to 163 mm. Hab. Djampea and Kalao. 



5. Treron griseicaiula vorderraani : Very closely allied to T. g. paUidior, but 

 slightly more gpeen below, somewhat more greyish throat. Wing of males 165 to 

 167 mm. Hab. Kangean Islands. 



4. Treron vernans (L.). 



Culumla vermnis Linn., Mant. (1771) p. 526 (ex Brisson — hab. Ins. Philippin.) — Trerun vermins 

 Vorderm,, Xnluiirl. T'ljihchr. XeJ. Iiid. LII (1893) p. 202. 



S ad. Kangean E., ? Kangean W. " Iris rosa, Fiisse fleischroth, Schnabel 

 blauweiss." (Nos. 64,73.) Local name : " walik." 



(?, wing 162, ¥ 158 mm. Vorderman quotes the wing of his male as even 

 167 mm. long, and both our specimens being worn it may be that my measurements 

 are rather too small. In any case they clearly show that we know a very large race 

 from Kangean. 



I have on a former occasion (Nov. ZooL. II, 1895, p. 476) already discussed the 

 remarkable difference in size of Trermi vernans. I may add that I can only confirm 

 my former observations, and that Philipi)ine s|jecimens are generally, though not 

 without exceptions, very small.

* I do not think that Osmotrertm is a well-iletineil fjenus. This view is illustrated Ity Treron sau- 

 girnnsiit, and in fact by all the forms of the grixeicaitda group, in which the soft space between the 

 rhamphoteca and the feathers of the forehead is in extent between that of Trenm nipaleims and 

 '• Osmotreroyi " tdnx. 



t There is no reason to reject Miiller's name, Linnaeus' Coluvib.z iiidira belonging to a very different 

 genus. Miiller douljtless named Daubenton's "Tourterelle de Batavia" I'olumba imlica. It is true that 

 Miiller's diagnosis is a most wretched and misunderstood description of Daubenton's figure, and that he 

 quotes " Button." The latter, however, did not give a description at all, and Miiller clearly described tlic 

 figure ; besides he always quotes Daubenton's plates as " BufEon," as they really belong to BuSon's Uitt.
