without olive tinge, darker on piieuni ; upper tail-cov^erts and edges 

 of rectrices, reuiiges, and greater wing-coverts rusty. Chin, throat 

 and jugulum pale ash-gray; rest of lower parts very pale sulphur- 

 yellow. Wing, 3.00 ; tail, 2.00 ; culmen, .85 ; bill from nostril, .50 ; width 

 at base, .33; tarsus, .80; middle toe, .42. 



This bird is so closely related to M. harhirostris^ of Jamaica, that it 

 should perhaps be considered merely a local race of it. However, the 

 general coloration is very distinct on comparison ; but to what extent 

 this ditt'erence is due to action of alcohol on the feathers — the speci- 

 men having been preserved in spirits and afterwards skinned — is not 

 known. 



40. Contopus schottii Lawr. ? 



Four si)ecimens, which uniformly differ from the type of C. schottii in 

 decidedly grayer coloration above, with the pileum darker. They may 

 represent a distinct form. 



r 41. Empidonax gracilis Ritlgw. (^^E. minimus, Baird!) 



EmpidoHcix gracilis RiDGW. Descr. New Sp. B. Cozumel, February 26, 188^, 3. 



Sp. char. — Most like E. minimus, but the plumage much grayer, the 

 lower parts without yellow tinge. 



Adult 9 (No. 102,737, U. S. Nat. Mus., Cozumel, January 22): Above 

 ash-gray, more brownish, but still decidedly gray, on lower back, rump, 

 and upper tail-coverts; a distinct orbital ring, two broad wing-bands, 

 and broad edges to tertials grayish-white; sides of head light ash- 

 gray, fading to grayish white on throat; jugulum and sides of breast 

 light brownish gray ; restof lower parts white. Wing, 2.50; tail, 2.20; 

 culmen, .55 ; bill from nostril, .25 ; width of bill at base, .23; tarsus, .GO; 

 middle toe, .30. 



This bird, of which a single specimen was collected and preserved 

 in alcohol, so closely resembles the female of E. minimus, Baird, in 

 dimensions as to cause a suspicion that it may be in reality a specimen 

 of that species with all the yellow coloring abstracted from the plumage 

 by the action of the alcohol in which it had been preserved before skin- 

 ning. Still, the difference of coloration is much too great to allow of 

 this hypothesis determining the question. 



42. Elaiuea martinica (Linn.)? 



Two Specimens, one skinned'from fresh bird the other from alcohol. 

 The former I am unable to distinguish satisfactorily from some Domin- 

 ica specimens; but the latter is very different in appearance, all the 

 yellowish tints having been extracted from the plumage by the alcohol, 

 leaving the color dull brownish gray above and dull pale gray or gray- 

 ish white beneath. 



- 43. Elainea placens Scl. ? 



Four examples, two skinned from fresh birds and two from alcohol. 

 The former agree very closely with Guatemala specimens of ^. placens,
