BIRDS FROM NORTH CELEBES RILEY. 



99 



running from forward border of nos- 

 tril toward tip of bill. 



Ramus to symphysis with gonys 

 nearly equal to the latter. 



Lores more or less naked, except for 

 the eye-ring. 



Frontal antiae poorly defined and 

 sparsely feathered and not extending 

 far forward on the bill. 



Bare superciliary and post-ocular 

 space small. 



Outer primary greater than half the 

 second, broader. 



Feet proportionally heavier and 

 longer; middle-toe and claw equal to 

 four-fifths tarsus; outer-toe without 

 claw extending to about the middle of 

 the ultimate joint of middle-toe. 



Tail-feathers narrower and rounded 

 at the tip ; the two outer on each side 

 only very slightly shorter than the 

 others. 



tinct line or stria from the forward 

 border of the nostril toward tip of 

 bill. 



Ramus to symphysis with gonys less 

 than one-half the latter. 



Lores feathered. 



Frontal antiae well defined and 

 well feathered, extending well for- 

 ward on the bill. 



Bare superciliary and post-ocular 

 space proportionally greater. 



Outer primary equal to about one- 

 half the second, narrower. 



Feet proportionaly weaker and 

 shorter; middle-toe and claw equal 

 to three-fourths tarsus ; outer-toe with- 

 out claw extending beyond the mid- 

 dle of the ultimate joint of middle-toe. 



Tail-feathers broader and obliquely 

 rounded at the tips ; the two outer on 

 each side appreciably shorter than the 

 others. 



Some of the above differences are only relative and probably 

 specific, yet there are so many structural differences remaining be- 

 tween the two genera that to think of uniting them would be unrea- 

 sonable. Judging from what specimens I have seen and the litera- 

 ture, MeliUstes is monotypic, so far as known at present, which agrees 

 with Stresemann's^« conclusions. The genera Arachnothera and 

 Arachnorhafhis superficially resemble some of the Meliphagidae 

 and have the commissure serrated at the tip, but so do some of the 

 other genera of the Nectariniidae. If T oxorha7nphus Stresemann 

 (type Cinnyris novaeguineas Lesson) is allowed to remain in the 

 Meliphagidae, then it would appear as if Arachnothera and Arach- 

 norhaphis should be placed near it in the same family. HaTtert " 

 in discussing MeliUstes fergussmm has already questioned the right 

 of Arachnothera as a member of the Nectariniidae.
