Sir, — In the last number of your Journal (1874, pp. 416 

 -420), Dr. Sclater gives a short account of the contents of my 

 ornithological papers in the ' Sitzungsberichte ' of the Im- 

 perial Academy of Sciences of Vienna for 1874. Dr. Sclater 

 concludes with the " fifth memoir (read June 18, 1874).^' As 

 I published six memoirs in the ' Sitzungsberichte ' (as Dr. 

 Sclater himself remarks on page 416), I beg leave briefly to 

 point out to the readers of ' The Ibis ' the contents of this 

 sixth memoir (read July 16, 1874). 



Rhipidura rufidorsa, from New Guinea and Jobi (allied to 

 R. dry as, Gould), and Rhipidura kordensis, from Mysore, are 

 described as two new species, as well as Myzomela cruentata, 

 from the Arfak mountains, and Myzomela rubrobrunnea, from 

 Mysore ; some specimens of a Myzomela, from New Guinea, 

 are provisionally registered as M. erythrocephala, Gould. 

 Ptilotis pyrrhosis is a new species from Jobi ; and Ptilotis me- 

 garkijncha. Gray, is proved to be a young Ptilotis rostrata, 

 Wallace ; then follow some remarks on Xxtnthotis chrysotis 

 (Less.) and allied forms. Tropidorhynchusgilolensis, Temm., 

 Antkochara senex. Gray, and Melitograis striata, Sundevall, 

 are shown to be identical ; a Tropidorhynchus from New 

 Guinea is provisionally determined as Tropidorhynchus inor- 

 natus, Gr. & Mitch., likewise another bird provisionally as 

 Gliriphila modesta. Gray. Cosmetira eques (Lesson) varies 

 considerably in size and coloration. Mimeta striata (A. & G.) 

 has a black bill when young, a red one only when full-grown. 

 The sexual differences occurring in the different species of 

 Dendrochelidon, especially in Dendrochelidon mystacea (Less.), 

 are then discussed. The paper concludes with detailed re- 

 marks on the following Parrots (pp. 21-39) : — Pionias pu- 

 cherani (Bp.) et stirpes; Trichoglossus cyanogrammus, Wagler; 

 Domicella Jori (L.) et stirpes [D. Im-i (L.), D. lori jobiensis , 

 n. var., D. cyanauchen (Miiller)], D. cyanogenys (Bp.), D, 

 fuscata (Blyth), and Z>. scintillata (Temm.). In a note the 

 correct spelling of the names " Mafoor " and '' Mysore " is 

 spoken of.
