1. P, arctitorqiiis arctitorquis : Teuimber group. 



2. P. arctitorquis kebircntsis : all the Soutli-West islands from Babber to 

 Moa, Dammer and Roma. 



Or: 



1. P. arctitorquis arctitorquis : Tenimber group (smaller, ? more cinnamon). 



2. 1\ arctitorquis kebiretisis : Babber and Dammer (larger, ? more brownish). 



3. P. arctitorquis subspec. nov. : Roma, size of 2, ? more greyish). 



4. P. arctitorquis subspec. nov. : Moa (colour as 3, but smaller). 

 I prefer to adopt the former course for the present time. 



ZOSTEROPIDAE. 

 11 T. Zosterops lettiensis Finsch. 



ZfKtei-ops lettiensis Finsch, Notes Lrydtn .Vus. 18".I8. p. 13(5 (Letti) 



I am obliged to use binomials for forms of the genus Zosterops in most cases, 

 as I cannot venture just now to review tlie whole genus, in order to arrange it in 

 species and subsjjecies. I cannot, however, agree with Dr. Finsch, who unites 

 Zosterops lettiensis with griseiventris from Tenimber, which is smaller (if correctly- 

 measured, males being compared with males &i\A females vi\t\i females) and greyish 

 on the sides. Though the birds from Moa and Letti, Kisser and AVetter, are 

 extremely near to griseieentris, they are not more difl'erent from citrinella of Timor, 

 Savn, and other Sunda Islands ; in fact, they only differ from citrinella in having 

 considerably larger bills, being perhaps (on an average) paler yellow on the throat 

 and generally slightly longer in the wing. 



I cannot see my way to follow Dr. Finsch {Zosteropidae, Tierreich LieJ. 15. 

 p. 16) in recognising two species on Timor — namely, citrinella on Timor alone and 

 neglecta on Timor and eastwards to Java. Our very large series leaves the possi- 

 bility of separating the Timor form, being slightly darker, and allowing neglecta to 

 inhabit Java to Flores ; but the differences are so slight, so inconstant, that I do 

 not venture to do this. If, however, future material from all islands collected at 

 the same season should induce any one to do snch splitting, then the Alor birds, 

 which are very yellowish above and have brighter yellow upjjer tail-coverts, must 

 also be distinguished. I do not venture to do so at present, having only two 

 specimens from Alor. The followingiforms are evident enough : 



Z. citrinella, Timor to Java : bill smaller. 



Z. lettiensis, AVetter, Kisser, Moa, and Letti : bill larger. 



Z. bassetti, Dammer and Roma : browner on the underside. 



Z. griseiventris, Tenimber : smaller and greyer on the sides underneath. 



All these must be subspecies of one species, but I am not certain about the 

 oldest name of the latter. 



Mr. Kilhn sent the following specimens of lettiensis : 



6 cJ(J, Letti, November, December 1902. (Nos. 5984—5986, 6446—6448.) 



4 c?(?, 2 ^? , Moa, November 1902. (Nos. 6178-6180, 6303, 6304.) 



6 c? c?, 3 ? ? , 2 ?, Kisser, April— June 1901. (Nos. 3842—3846, 3943, 4022— 

 4025, 4105, and two without numbers.)
