1. Parus annexus, nobis. 



Form. Crested; bill strong, conical; fourth and fifth quills longest and equal, 

 wings and tail rather long, crest pointed. 



Dimensions. Total length (of skin) from tip of bill to end of tail about 5 

 inches, wing 2 J, tail 2i inches. 



Colors. Sex unknown. Anterior feathers of the crest black at their bases and 

 cinereous at their tips, the most elongated of the succeeding entirelyblack, others 

 margined with white, shorter occipital feathers, black ; chin and throat black. 

 Wide line from above the eye running into the crest, thence around upon the side 

 of the neck, white. Line commencing behind the eye, running thence around 

 and uniting with the space of the same color upon the throat, black, cheeks 

 white. Entire superior surface cinereous, tinged with olive, quills and tail 

 feathers brownish black, primaries narrowly edged externally with white, 

 secondaries and tail feathers edged externally with ashy olive. Body beneath 

 ashy white, darker upon the breast. Bill black. 



Hai. Texas, upon the Rio Grande, discovered by Mr. John Woodhouse 

 Audubon. 



Obs. This very remarkable species, discovered in Texas by a son of the illus- 

 trious naturalist of the same name, is marked upon the head more like the P. 

 eristatus of Europe than any other American species yet known. It does not 

 resemble that species in any other character, however, being more strictly 

 related to P. bicolor, Linn, and P. inornatus, Gamb., and like them belonging to 

 the genus Lophophanes, Kaup. 



2. Partes atricristatns, nobis. 



Form. Crested, wings and tail rather long. Crest pointed as in P. bicolor, 

 Linn., bill strong, conical. Specimen now described not in mature plumage. 



Dimensions. Total length of skin from tip of bill to end of tail about 5 inches, 

 wing 21, tail 2i inches. 



Colors. Sex unknown. Crest black, front and under parts of the body ashy 

 white, flanks ferrugineous ; entire superior surface cinereous, darker upon the 

 wings and tail, and inclining to olivaceus upon the back. Bill and legs black. 

 Shafts of primaries reddish at their bases, those of the tail feathers white beneath. 



Hab. Texas, on the Rio Grande, discovered by Mr. John Woodhouse 

 Audubon. 



Obs. This species is of the same general form and color as P. bicolor, Linn. 

 and P. inornatus, Gamb.; smaller than the former, but about the sizeof the latter. 

 It may be easily recognized by its black pointed crest and white front, which, so 

 far as I know, are peculiar chaiacters. This species, like the preceding, was 

 discovered in Texas by Mr. Audubon, and belongs to the same genus.
