3cT, 4tli, 5tli and Gtli longest. Tail as in M. geniharhis; tail-feathers 

 eqnal to or a little longer than the wing. 



Whole upper parts slaty plumbeous with a conspicuous olivaceous 

 wash, becoming more intense on the lower back, but lacking on the 

 rump and upper tail-coverts. The pattern of the head that of M. (jeni- 

 harhis, except that the black stripe below the eye extends further back 

 on the auriculars, and that the white part of the malar stripe occupies 

 the forward half. Chin pure white, this color abruptly defined against 

 the throat, which is rufous-chestnut. The remaining underparts like 

 those of the Martinique bird, except that the gray of the breast ex- 

 tends more backward on the abdomen. Wings and tail also have 

 the same general appearance as in the above-mentioned species; on the 

 wings, however, the black speculum of the secondaries is more reduced, 

 the adjacent grey cross-bands being broader, and on the tail the white 

 is more extended, especially on the outer pair, in which the middle third 

 of the outer web is white; besides, the outer webs of the three outermost 

 rectrices are broadly tipped with white, and the following two jwirs 

 have also very distinct white tips. Bill black, feet pale yellow. 



In none of the seven specimens before me is the sex indicated ; but 

 as they show no differences from the specimen described above, I i^re- 

 sume there is no difference between the male and female. 



Tahle of dimensions. 



Hab. — Santa Lucia. Mr. Semper (1. c.) states these birds are " gen- 

 erally found in the virgin forest or near it," and that " they are fond of 

 cool shady places on the hills and high lauds." 



Eemarks. — Although very nearly allied to the foregoing species, the 

 M. sanctce-luci(B is easily distinguishable by the well defined white chin, 

 the greater amount of white in the malar stripe, the darker, more chest- 

 nut shade of the rufous of the throat, the greater extent of the gray on 

 the lower parts, and by the olivaceous tinge of the back in front of the 

 rump. 



The differences from the next form, M. dominicanvs, will be pointed 

 out under the head of the latter.
