 364. Troglodytes musculus rufulus (Cab.). 



Troglodytes tessellatus SALV. & GODM. Ibis, 1879, 198 (Marocaso) ; ibid. 

 1880, 117 (Santa Marta). 



Troglodytes rufulus SHARPE, Cat. Eds. Brit. Mus. VI, 1881, 258, in part, 

 the reference to the above-mentioned Santa Marta specimens. 



A series of 8 specimens is provisionally referred to this sub- 

 species, taken as follows : Minca, June 21 ; Cacagualito, May 16 

 and 17 (4 specimens, i juv. in first plumage) ; Cienaga, Sept.;' 

 Bonda, June 22 (juv.) and Oct. 8 ; Minca, June 21. 



These examples agree very well with examples from Trinidad, 

 in several instances specimens from the two localities being prac- 

 tically indistinguishable. The Trinidad specimens are apparently 

 strictly referable to the type form of rufulus from Guiana. Mr. 

 Sharpe (/. c.) also considers British Guiana (Bartica Grove) speci- 

 mens " identical with the Santa Marta race." 



365. Thryothorus laetus Bangs. 



Thryothorus Icetus BANGS, Proc. Biol. Soc. Wash. XII, 1898, 160 and 180 

 (Pueblo Viejo and Palomina). 



Six specimens : Onaca, Dec. 20, ad.; Cacagualito, May 28 and 

 29, ad. and juv. in first plumage ; Minca, July 6, 22, and 26, 2 

 ad. and i juv. 



The young in first plumage has the head nearly concolor with 

 the back, which latter is similar in color to that of the adult ; the 

 throat is dull grayish brown, almost without black spotting ; the 

 breast is buffy olivaceous brown, without spotting, and the rest 

 of the lower surface is nearly uniform dull olive brown with 

 a tinge of buff. The young appear to molt directly from this 

 plumage into that of the adult. 



366. Thryophilus rufalbus castanonotus ( 



Thryophilus rufalbus SALV. & GODM. Ibis, 1880, 116. Minca. 

 Thryophilus minlosi BANGS, Proc. Biol. Soc. Wash. XII, 1898,. 144 (not of 

 Berlepsch). Santa Marta. 



Ten specimens, collected as follows : Cacagualito, May 7 

 June 2 ; Bonda, March 15 and Nov. 24 ; Minca, July 31. 



These specimens agree well with specimens from Panama, on- 

 the one hand, and with examples from Cumanacoa, Venezuela, 

 on the other. The Thryophilus minlosi Berlepsch, from Bucara-
