hitherto called J/, melanogastra, onght to bear the next available name, M. luctuosa 

 Pelz., of which I have likewise seen the types, and its proper appellation is, 

 therefore, M. axiUrnis luctuosa Pelz. 



64. Myrmotherula longipennis Pelz. 



Myrinotherula longij/etmis Pelzeln, Ziir Oiu. Brasil. ii. (1868) p. 153 (Marabitanas and Rio Negro). 

 M. brevicauda (neo Swainson !) Solater & Salviu, P. Z. S. 1867. p. 576 (Capim River, the (J only). 



2 (?c? ad., 30 X., 15. xi. 0.5. Nos. 40, 130. "Iris brown."— Wing .59*, 60; 

 tail 33 ; bill 13i, I4| mm. 



These two skins have the middle of the breast and the cheeks decidedly paler 

 grey than the rest of the plnmage, and the ear-coverts show distinct silvery-white 

 shaft-lines, which are entirely wanting in the types of the species and in one c? ad. 

 from Snapure, Canra River. 



I have examined the specimens recorded by Sclater & kSalvin s. n. M. brevi- 

 cauda. The S belongs to M. longipennis, agreeing perfectly with Guianan examples 

 in size and coloration except the lower surface, which is mnch clearer grey, almost 

 as pale as in M. beidepschi Hellm. ; bnt I feel snre the colour has been altered 

 by some external influence. 



The so-called ? , however, belongs to M. a. axillaris (Vieill.). 



6.5. Myrmotherula hauxwelli hellmayri Snethlage. 



M. It. hellmayri Snethlage, <Jni. ilonbrr. xv. (1906) p. 9. descr. orig. {J (no locality given, the types 



came apparently from Panl). 

 Mi/rmntherula spec. ; Hellmayr, Nov. Zool. xii. (1905) p. 285 (Pard). 



3 (?c? and 3 ? ?, collected 15, 24, 28. x., 1, 26. xi. 05. Nos. 14, 16, 33, 36, 

 50, 213. Iris marked as " brown" or " blackish brown." 



These specimens differ from a good series of true M. hauxwelli by the complete 

 absence of the white interscapular patch; besides this, the females have the 

 upper jiarts of a warmer olive-brown. The male has been fully described by 

 Miss Snethlage. 



M. hauxwelli does not belong to the section of M. axillaris, where it has 

 been placed by Mr. Sclater {Cat. Birds xv. p. 237), bnt it is a very near ally of 

 M. guttata (Vieill.). In fact, both species agree perfectly in the markings of the 

 wing-coverts, tertials, npper tail-coverts, and rectrices, and in the shortness of 

 the tail. The only difference between the males consists of the colour of the 

 abdomen, which is ferruginous red in M. guttata, and slate grey like the breast in 

 M. hauxwelli. The females differ only by the colour of the throat and breast. 

 These are pale l)uffy browni.sh in M. guttata, while in M. hauxwelli the whole 

 nndersurface from the chin to the crissum is bright ferruginous. 



66. Formicivora grisea (Bodd.) 



Tnrdus grieseus (sic) Boddaert, Tahl. Pl.etil. 1783. p. 39 (ex '• Le Grisin de Cayenne," Daubeuton, 



PI. oil. 643. fig. 1 = ^.—Cayenne). 

 Furmirirora gnxea Sclater & Salvia, P.Z.S. 1867. p. 576 (Rio Tocantins) ; Pelzeln, Ziir Ornith, 



Brasd. ii. (1868) p. 73 (Pard) ; Lay.ard, Ihia 1873. p. 387 (Pard). 



3 c? <? and 2 ? ? ad. : 4, 8, 21, 23. xi., 20. xii. 05. Nos. 60, 80, 170, 182, 386. 

 " Iris brown." 



This series agrees well with specimens from British Guiana and Bahia, the 

 females being bright ochraceous underneath except the whitish throat.
