Tiie wi'stera foriu, M'/iohiits cnjtlirtiriis fulmgulans Salv. k Godm., is qnite 

 flistiiict in liiiviiii; the tVoiitnl region more rnfescent than the \\\)\wv head, in having 

 the throat more strongly snti'nsed with ochre-einnamon, and the breast and abdomen 

 also of a deeper ochraceons cinnamon.

Altagracia: J(? 2, 22, 14. xii., 13, ai. i., 1, 5. ii., 29. xi., ?? 13, 24. i., 1, 5. ii., 

 16. xii. " Iris seal. Iris Vandyke ; feet slate ; bill black."

(Nos. 8924, S971, 9199, 9261, 0353, 9669, 967(1, 9758, 9759, 9794, 992U, 9921,

Muscicajia pilmta P. L. S. Milll., Satur,y,t. Huppi. (1776) p. 172 (ex PI. Enl. 574 fig. 2.— Cayenne). 

 Mu^-Jcapa oUva Bodd., Tabl. PL Enl. (1783) p. 34 (ex PI. Enl. 574 fig. 2.-Cay6nne). 



Snapnre : ? 24. iv. '99. " Iris brown ; feet light grey ; bill black and white" 

 (S. M. Klages coll.). 



AI. o9i, caud. 55J, culm. IH, tars. 13 mm. 



The specimen agrees perfectly with a skin collected by Goeriug at C'aripe, and 

 with another of the so-called Orinoco make in Mus. H. v. B. 



The above name is somewhat doubtful. Uaiibenton's figure and Buflbn'g 

 description in the Hist. Nat. Ois. IV. p. 544 (under the name of " Le Gobe-Mouciie 

 olive de Cayenne ") are poor and by no means very clear. It is therefore somewhat 

 arbitrary to accept Miiller's name, but in any case it has the priority over M. oliva 

 of Boddaert. If M. pikata is not accepted, a new name must be created. 

 Empidochanes altirostris Cab. is apparently the same as E. arenaceus. 



175. Horizopus brachytarsus depressirostris (Ridgw.) ? 



{Cmtopus hnirhijtarms Scl., Ibis 1859 p. 441 (typus ex Cordova, Mexico, Salle' coll,).] 



Contopus ,1,'preesh-Oflris Kidgw., Prnc. C.S. A'ul. .Mus. VI. (1883) p. 403 (Los Sabalos, Nicaragua). 



Altagracia : " ?" in freshly moulted plumage, 16. xii. '97. 



" Eyes seal ; feet black ; bill black above, pale below." (No. 9252 Cherrie coll.) 



Al. 66i, caud. 59i, culm. 11|, tars. 12^ mm. 



The female from Altagracia agrees fairly well with spi'cimens from Pto. ('abello 

 (in Mus. H. V. B.), but differs by presenting smaller diiuensions, esjiecially a smaller 

 bill, by having the back a little more sulfused with greenish, the abdomen somewhat 

 more strongly tinged with snlphnr-yellow, the breast less ashy, and by having 

 broader whitish borders to the larger upper wing-coverts and inner secondaries. 



These dift'erences are slight, and some may be due to difference of sex (the 

 Altagracia specimen being a female) or age. A larger series of specimens must 

 therefore be examined, and if possible compared with the type of Hidgway's 

 depressirostris in order to make out satisfactorily the proper name to be attached 

 to the specimen from the Orinoco. 



Contopus aHdinu.% Tacz., P.Z.S. 1874 p. 539 (Juuin, Central Peru), is larger, 

 and, judging from the measurements given by Taczanowski, seems to be the same 

 as C. virens (L.)
