 There are sixteen specimens of this apparently new Zosterops in 

 the present collection, obtained at various dates in the localities above 

 mentioned. The irides are noted as " reddish brown." 



The species belongs to the group of Z. albioentris ; but appears 

 to be distinguishable by its greyish abdomen, which is only whiter 

 in the middle line. 



24. Gerygone dorsalis, sp. nov. 



Supra bru)inescenti-castanea, alis caudaque nigris dorsi colore 

 Umbatis, pileo et nucha murino-brunneis ; subtus alba, hypo- 

 chondriis rufescenti lavatis ; subalaribus albis ; caudce rectrici- 

 bus subtus in pogoniis interioribus ?iigricantibus macula versus 

 apicem alba preeditis ; rostra et pedibus nigris : long, tola 4*0, 

 alte 2'\, caudce r6, tarsi 0'8. 

 2 . Mari similis. 



Hah. Larat, Loetoe et Moloe insulas Tenimberenses. 

 I was rather uncertain as to the correct position of this little bird, 

 which is quite distinct from any thing that I am acquainted with ; 

 but Count Salvadori, to whom I have sent a skin for examination, 

 kindly tells me it is a Gerygone. The bill is rather compressed, and 

 the tarsi are long and slender. The third, fourth, fifth, and sixth 

 primaries are nearly equal and longest. The irides are noted as 

 black. 



25. MiMETA decipiens, sp. nov. 



Fuscus fere unicolor, super ciliis albidis, pilea nigricanti striolato i 

 subtus paulo dilutior, gutture et cervice antica albis, prcecipue ad 

 latera nigra guttulatis ; pectoris summi plumis quibusdam nigri- 

 canti striolatis ; regions auriculari nigricante ; rostra et pedibus 

 nigris : long, tota 11 '8, alcB 6-5, caudce 50. 

 Hob. Larat uisulam Teuimberensem. 



Obs. Similis M. bouraensi, sed gula albida nigro transversim gut- 

 tulata et pectoris summi plumis nigricanti striolatis distinguendus. 



Two specimens of this Mimeta, marked " irides dark brown," are 

 in the collection. They so closely resemble Phileman piuuagenis in 

 general appearance, that I had at first marked them as of that species^. 

 Adding the new species now described and Cacatua sanguinea 

 and Stigmatops squatnata to the list given in my first communication 

 we shall find that, so far as we are acquainted with the birds of the 

 Tenimber Islands from Mr. Forbes's researches, its avifauna embraces 



' Cf. Wallace, P. Z. S. 1863, p. 26, on a similar case of mimicry m another 

 species of this genus.
