576 DR. O. FINSCH ON THE BIRDS OF RUK. [NoV. 16, 



resembles that of M. pluto from Ponape. It is cup-shaped, 12'" 

 deep by 20'" to 24'" ia diameter, and consists of fine grass fibres, 

 &c., covered all over outside with moss and lichen. Tlie egg 

 (c. 10'" long) is of a shining cream-colour, passing faintly into isabel- 

 line, A little above the centre, towards the larger end, there is a 

 bi-oad ring of reddish-brown spots, which are confluent and are mixed 

 with some greyish ones ; the remaining portion of the egg has a few 

 reddish speckles. The nest is placed on the branches of trees, and 

 contains mostly a single egg, seldom two. The breeding-season is 

 nearly the whole year through. I inspected eggs collected in May, 

 June, and August. 



This is a very good species, and by no means identical with 

 M. albiventrit, Peale, as was suggested byus(Ornith. Centralpolyn. 

 p. 93). I add a short description : — 



Male. Upper parts slate-grey; wing and tail darker, of a brownish 

 black ; head above with steel-black lustre ; underparts white ; chin 

 pale ; throat and upper part of a bright rust-red. 



Female. Like the male, but paler ; above smoky brown ; head 

 above the same, underneath with only the throat washed with rufous- 

 yellow. 



Long. al. caud. rostr. Lat. rostr. Long. tara. 



3" 2" 7'" 6'" 4'" 9'" 



This species is much larger than M. albiventris ; the latter has 

 only the chin and throat vivid rufous-red and the upper parts 

 black. 



7. Calornis pacificus (Gm.). 



Specimens from Ruk agree with others from Ponape and Kushai, 

 although some look apparently a little more shining. A young 

 male has the feathers of the underparts from below the throat dis- 

 tinctly margined on the sides with whitish, forming light longitudinal 

 stripes, as I described in Palau specimens. 



*8. Erythrura trichroa (Kittl.). 



9. Ptilopus ponapensis, Finsch. 

 Agrees with Ponape specimens. 



*10. Carpophaga oceanica, Less. 



11. Phlogcenas erythroptera (Gm.). 

 Agrees with specimens from Ponape. 



*12. Strepsilas interpres, L. 

 *13. Charadrius fulvus, Gm. 



14. NUMENIUS PH^OPUS, L. 



This is perhaps rather N. uropygialis, as the specimens have a 

 dark-barred rump. 



*15. ACTITIS INCANA (Gm.).
