This hitherto overlooked species diiFers from M. surinamensis in the male sex 

 in its much longer tail, the much wider black stripes on the under surface, the 

 middle of the throat and abdomen also being striped, rather wide white tips to 

 the rectrices, shorter white borders to the feathers above, so that the upper surface 

 appears blacker, and black mandible as well as maxilla. The female is still more 

 strikingly distinct. The crown and hindneck are black with buff edges to the 

 feathers, the under-surface is buff striped with black. The tail is much longer. 

 The sexes are equally large. 



Hartert has examined the series in the British Museum, and finds tliat the 

 skins from Oyapoc, in Southern Cayenne, belong to our new species, one of them 

 (already queried by Dr. Sclater), however, apparently erroneously labelled, being 

 M. surinamensis. 



These birds have nothing to do with Sclater's multostriuta. 

 M. multostriata * (type from Dcayali, Peru) has a female with a striped 

 nnder-surface ; but the stripes are narrower, and the crown is black with deep 

 rusty cinnamon edges to the feathers ; the males are whiter below, with the 

 black stripes narrower ; the middle of the throat and abdomen are almost pure 

 white ; moreover the adult male has a whitish under mandible. Sclater was wrong 

 when he stated {Cat. B. Brit. Mus. XV. p. 231) that his multostriata was based on 

 young males ; nor does the series in the British Museum show that " intermediate 

 forms are represented in specimens from Panama, Guiana, and Colombia." The 

 striped under-surface of multostriata stamps it as at least a very well marked 

 subspecies of M. surinamensis. 



Onr M. cherriei is, by its long tail, somewhat more allied to M. longicauda 

 Berl. & Stolzrn.,! from Central and North Peru and Bolivia, which, however, has 

 the throat and middle of the abdomen uniform white, unstriped in the male, and 

 a still longer tail. T\\g J'etnale of lo?igicauda h&s the crown black with buff, not 

 chestnut-rufous edges, and the under surface is much lighter and very little striped.
