Adult male. Similar to that of T. nigrofasciata, but smaller. 

 Length of wing 2-15 inches, tail 1-35, bill "88. 



Unknown to me. Mr. Elliot, who compared the type with spe- 

 cimens of T. nigrofasciata, says there is absolutely no difference 

 between the two except in size. This difference is not great, and I 

 think T. jelskii must be considered a species of doubtful value,

 Polytmus furcatus. Gray, Hand-l. B. i. p. 1£0. 



Adult male. Upper surface nearly black when viewed from in 

 front, with a slight shade of green, which is brighter on the rump ; 

 interscapulium glittering blue ; throat glittering green ; abdomen 

 glittering blue ; under tail-coverts black, with white edges and 

 green discs ; tail steel-blue ; bill black. Total length about 4-3 

 inches, wing 2 ; tail, central rcctrices O'S, lateral 1-75 ; bill 0-85. 



Adult female. Upper surface shining grass-green tinged with 

 golden, central rectriccs darker and bluer; under surface dusky 

 white, lateral rectrices steel-blue, grey at the base, and tipped with 

 white. 



Home Cayenne skins have the tail longer and more deeply forked 

 than others. Count Berlepsch tells me that he believes that the type 

 of T. forfieata. Cab. & Heine, really came from Cayenne, and not from 

 Para, and is one of the long-tailed individuals of T. furcata.
