N.B. — Tlio above is tlie proper name for tlie species commonly called C. pcrsiciis, 

 as has been brony:lit to my attention by Count Berlepsi-h. Linne's diagnosis of 

 Parus cela reads as follows : " P. niger, rostro albo, macula alarnm basiqne caiidae 

 flavis, Mus. Arl. Fi: 2. p. . . . Habitat in Indiis." Turning to the " Museum Ad. 

 Frid.", we find but one species, T<i/iai/iri nlhiroxtris, to which this description can 

 a]iply. The diagnosis given ibr that bird is the same, word for word, but a more 

 detailed account is added that renders the ideutilication absolutely certain : (!f. 

 " corpu.s sturno fere mains, nigrum, basi pennarum in tergo albo."

A good series from Chaguaramas, January ; Seelet, April ; C'ai>aro, March and 

 April ; Pointe Gourde, January; Laventille, March. 



These examples have generally longer and stronger bills than others from 

 ( 'umana and the Orinoco valley, and the wings average 2 to 3 ram. longer. One 

 specimen from Margarita Island is somewhat intermediate. X. x. curaqoensis 

 (Ridgw.) has the bill still longer and more slender. 



Immature birds are much less brightly coloured tlininghonf, more greenish 

 yellow aljove and less orange below.

Tiiese sjjecimens agree in coloration and size with a series from Tobago 

 {M. >ni)iimn.s Dalm.) and with the type of J/, iit/onitens Cab. in the Berlin Museum. 

 I suspect that Ualmas, when describing his M. mini/mis, compared it with 

 M. renezuelethvs Stone, which he might have mistaken for M. atronitens. 

 M. renezuelethv.'i is indeed mucli larger than the latter species, as will be seeu from 

 the following measurements.
