in the Paris Mnsenni ; while in the three others the white ends are followed by a 

 more or less distinct black snbapieal band, more pronounced on the onter rectricea 

 than on the inner ones. The two S S in the British Museum agree perfectly with 

 these specimens. 



The ? ? correspond well with Count Berlepech'a description.* No. 731 is 

 rather darker on the nnder-parts than the three others. The colour of the upper 

 surface varies from olive grey to dull olive. 



Although mixed up with .1/. longipennis in the Catalogue of Birds, M. menetriesii 

 is quite distinct from it, and much more nearly related to .1/. cinereiventris, 

 as correctly pointed out by Count Berlepsch. In fact, it seems to be its southern 

 representative, but the exact range in Peru of the two forms is not yet satisfactorily 

 established. M. cinereiventris is known to me from Pebas and Ljuitos, on the 

 north bank of the Maranou, and also from Chyavetas, south of that river, where 

 Bartlett collected several specimeus, while of M. menetriesii the British Museum 

 possesses an adult <?, said to be from Chamicnros. The rj of M. menetriesii differs 

 from that of M. cinereiventris merely by having the middle of the throat and 

 foreneck extensively black. The ? ? of the two forms I am unable to distinguish. 



Prof. Ihering has kindly sent me the type of M. brevicauda juruana, and I 

 found it to agree with the types of M. boliviano,. 



The range of M. menetriesii is, according to our present knowledge, as follows : 



North Bolivia : San Mateo (Garlepp). East Bolivia : Yuraeaivs (D'Orbigny). 

 X.E. Peru: Chamicnros (Hauxwell). N.W. Brazil: Rio Jurna (Garbe) ; Teffe 

 (Hoffmanns) ; Rio Javari (Bates). 



The (? of the present species differs from M. longipennis Pelz. by its much 

 shorter wings and tail, much paler, clear cinereous (Ridgw. pi. ii. 16) instead of 

 deep slate-grey coloration, whitish grey (not black) chin and considerably smaller 

 white shoulder-patch. The middle and greater npper wing-coverts are clear 

 cinereous with a sharply defined black auteapical spot which is followed by the 

 white tip (in .1/. longipennis they are black tipped with white and scarcely edged 

 with slate-grey along the outer web); the primary coverts show distinct white 

 apical margins which are entirely absent in M. longipennis; the axillaries and under 

 wing-coverts pale cinereous, not deep slate-grey, etc., etc. 



The ? ? of the two species are altogether different, that of M. longipennis 

 having the back warm wood-brown (Ridgw. t. iii. fig. 13), the upper wing-coverts, 

 the outer web of the cpiills and the edges of the rectrices bright russet, the abdomen 

 white, etc., etc. It is, moreover, much larger.
