The comparision ofCount Salvadori's specimens witli the British Museum series induces me to believe 

 that his E. mueUeri is not to be separated from E. tenuirostre. At the same time I must confess that the 

 Aru Island birds appear to belong to another race or even a distinct species. Thus a male from Lutor 

 (Beccari) is decidedly smaller than an other from Mansinam which has the wing 5.15^ whereas in the Lutor 

 bird the male has the wing only 4.6, the colour too is darker grey without the light edgings to the quills 

 which are margined with the same grey as the back. The femalc is deep fawn colour below, and has 

 regulär arrow shaped bars on the white of the under surface.excepting the throat, vent, and under tail- 

 coverts which are uniform. The eyebrow and sides of neck have a stroug chestnut tinge, and the quills 

 are edged with chestnut, wbile the back is brown instead of grey. This bird is also from Lutor, and as 

 both sexes seem to ditfer from the true E. tenuirostre, I fully expect that they will turn out to be distinct 

 in which case I should propose to call the species Edoliisoma aruense. 



The following is a list of the species which apparently belong to the genus Edoliisoma. 



1. E. cojrulescens (Blytk). Hah. Philippine Islands. 



2. E. nigrum {Garn.). Hah. New-Guinea: Aru Islands. 



3. E. dispar, Salvad. Hab. Ke Islands: Goram: Banda: Matabello: Tijor: Pulo-Padjang: Monawolka. 

 A good species: in the Museum from Goram (Wallace). 



4. E. montan um [Meyer). Hab. N. W. New Guinea. 



5. E. ceramense (Bp.) Hah. Ceram.: Amboyna: Mysol. 



6. E. salvad orii, Sharpe. Hab. Sangi Islands. 



7. E. timoriense, Sharpe. 



Similis E. ceramensi sed facie laterali pallide cineraceo, nee nigro. gutture cineraceo corpori reliquo 

 concolori: sexus dissimiles. Long. tot. 10, culmen 0.8, ala3 5.0, cauda3 4.5, tarsus 0.9. 



10. E. obiense, Salvad. Hab. Obi groiip of Islands. 



11. E. aruense, Sharpe. Hab. Aru Islands. 



12. E. incertum, Meyer. Hab. Islands of Miosnoum and Jobi. 



13. E. meyeri, Salvad. Hab. Mysore Island. 



14. E. remotuni, Sharpe. 



cf ad. vix ab E. meyerio distingueudus. Long. tot. 9.5, culmen 0.9,5, alte 4.95, caudre 4.05, tarsi 0.95. 



9 ad. smilis E. meyerio sed pileo cinerascenti-brunneo, nropygio et supracaudalibus rufescenti-fiüvis: 

 rectricibus centralibus rufescenti-brunneis distinguenda. 



Hah. New Hauover. 



The male of this species is cxceediugly like E. meyeri, but the female is quite diflferent. From E. 

 meyeri the hen bird differs in beiug ashy brown instead of slaty blue on the crown (the same sex of E. 

 melan having the head rufous brown), and also in having the rump and upper tail-coverts chesnut fawn- 

 colour instead of brown. The tj'pes are in the Berlin Museum, and were sent over for my examination by 

 the kindness of Dr. Peters. 



15. E. morio {8. Müller). Hab. Celebes. 



16. E. tenuirostre {Jardine). Hab. N. E. Australia. New Guinea. Aru Islands. 



17. E. uesiotis, Hartl. S,- Finsch. Hab. Island of Uap, Mackenzie group. 



The type of this species was kindly sent over for my inspection by the Godeffroy Museum, where 

 it still remaius unique. The specimen is unfortunately not fully adult, and is a female, but it differs quite 

 as much more than the hens of the allied species, and I fully expect that when the male is discovered, it 

 will be found to be a good species. The type comes nearest to the female of E. tenuirostre. 



18. E. grayi, Salvad. Hab. Halmahera: Batchian: Ternate: Morty Island. 



19. E. anale {Verr. et Des Murs.). Hah. New Caledonia. A species unknown to me.
