310 Mr. O. Salvin's Visit to the 



he could find no reference. The abbreviation here stands 

 doubtless for the genus Empidochanes, and not for Empidonax. 

 olivus is Boddaert's name for Buffon's Gobe-mmiche olive 

 de Cayenne (PI. Enl. 574. fig. 2). Mr. Ridgway's bird should 

 be compared with E. fuscatus (Max.), from Brazil; or with 

 Dr. Cabanis's E. argentinus, Journ. f. Orn. 1868, p. 196. 



Empidonax fulvipectus, Lawr. 



This appears to be a distinct species, having a general re- 

 semblance to E. bairdi, but with the outer web of the outer 

 rectrix whitish as in E. obscurus. The type is in Mr. Law- 

 rence^s collection. See 'North-American Birds/ ii. p. 364. 



CoNTOPus LUGUBRis, Lawr. Ann. Lye. N. Y. viii. p. 134. 



This species is a southern form of C. pertinax, and differs 

 from it chiefly in being of smaller size, slightly darker in 

 general colour, and in having the head of a darker hue. In 

 ' North- American Birds ' C. lugubris is treated as a " variety " 

 of C. pertinax. This view may be the correct one ; but it 

 must be remembered that these birds aflPect semialpine regions, 

 and therefore, the range of the stock being broken, the bird 

 is in all probability unrepresented in the low-lying valley of 

 the San Juan river and the lakes of Nicaragua. 



Thamnophilus HOLLANDi, Lawp, Ann. Lye. N. Y. viii. 

 p. 180. 



The types of this species which I examined in the col- 

 lection of the Smithsonian Institution appeared to me to 

 belong to the common T. melanocrissus , their bills being only 

 very slightly larger, not nearly enough to justify the suppo- 

 sition that T. hollandi is a distinct species.

 p. 172 (1865). 



This is identical with the bird I have called Myrmotherula 

 meneti'iesi, in my lists of Veragua birds (P. Z. S. 1867, p. 144, 

 and 1870, p. 195). The bird has a very wide range; and I 

 can see no satisfactory differences between Central and South 

 American examples. 



The following five species of this genus are all that have as
