Tin' ? J agree very well with (batterer's typical examples, except in being 

 decidedly less rufescent above. In fact, the colour of the back is exactly t ho same 

 as in the ¥ of //. p. vidua Hellm. //. p. griseiventris can, however, easily be 

 distinguished by the pale ferruginous chin spot, front and sides of the head, etc. 

 It is also rather larger, especially the tail longer, and the bill stronger. 



No. 885, a young male, has the general plumage of the female, but some 

 newly-grown feathers on the upper wing-coverts are black margined with white, as 

 in the adult c?. 



Telle is quite a new locality for //. p. griseiventris, which hitherto was only 

 known from Borba (liio Madeira) and Mattogrosso.

These birds have the belly of the same clear slate-grey as topotypical 

 specimens from British Guiana. The forehead seems to be less extensively 

 white, though one <J ad. from the Caura River is hardly different on this score.

This specimen agrees perfectly with females from North-eastern Peru, having 

 the head above broadly striped with black, and the underparts buff with narrow 

 but very distinct black shaft-stripes on the foreneck and breast (cfr. Menegaux 

 and Hellmayr, Bull. Soc. Pkilom. Paris, 1900, p. 48). 



Having now examined 5 cS 6 ad. and 9 ? ? of M. s. multostriata, I feel quite con- 

 fident as to the distinctness of this form, though the S ci differfroin M. s. surinamensis 

 only by their slightly shorter tails and rather more densely striped under-surface. 

 It appears that there occurs in Upper Amazonia another species of this group, 

 which is most nearly allied to M. longicauda Berl. & Stolzm. of ( Vntral and South-east 

 Peru, but distinguishable by its much shorter tail, etc. The British Museum 

 possesses three c?c? ; one collected by Bartlett on the Upper Ucayali, the two others 

 said to be from the Bio Napo, East Ecuador. More material is required to settle 

 the true status of this form. 



M. S. multostriata seems to be new to the Brazilian avifauna. I suspect, 

 however, that the specimens from the Bio Jurua, recorded by Von Ihering s.u. 

 M. surinamensis* will also turn out to belong to it.
