154 PROCEEDINGS OF THE ACADEMY OP 



Young. Green. Head, back of neck and chin black, the first spotted with 

 chestnut, front chestnut. Throat white ; upper part of breast brown, lower 

 parts paler brown ; crissum very light scarlet ; wings green, shoulders covered 

 with large white spots, forming a broad band ; primaries black ; rump green- 

 ish blue, tail black, bordered with blue. Bill black, end horn color ; feet light 

 flesh color. 



Of this species I have only a young bird from which to take my description, 

 but it differs so greatly from the young of any species of this family, or even 

 from any adult which I have had an opportunity of examining, that I have 

 determined to give it a name, trusting that some future ornithologist, more 

 fortunate than myself, may be successful in discovering the adult. The great 

 peculiarity of this species is its white shoulders, which is a characteristic I 

 have never before witnessed among the Pittidse, that portion of the plumage 

 in these birds being almost invariably of different shades of blue ; and as in 

 the majority of the species of this family, the young bear the plumage of 

 the adult from the period of leaving the nest, I feel assured that the adult of 

 P. leucoptera would have a conspicuous white wing. 



The first primary is all black, the 2d, 3d and 4th have more or less white 

 on the lower half of both webs, while the 5th, 6th, 7th, 8th and 9th are all 

 white, with the exception of the tips, which are black. 



I obtained my specimen from M. Parsaduki, of Paris, and upon the label is 

 only the word Ceylon, which I suppose is its native country. 



On CYPRINUS CORPOBALIS Mitch., referring it to the genus SEMOTILUS 



Rafmesque. 



BY CHARLES C. ABBOTT. 



In the Delaware River, and in certain of its contiguous streams, there exists 

 a large and unusually brightly tinted Cyprinoid, that bears many and strong 

 resemblances to the Leucosomus pulchellus. Upon a more careful observation, 

 however, it becomes evident, from the want of barbels and the variance of the 

 pharyngeal teeth and bones, that the species is generically distinct. 



Dr. S. L. Mitchell first made known to ichthyologists the species under con- 

 sideration, giving to it the name Cyprinus corporalis, and stated it to inhabit 

 " the Hudson in the neighborhood of Albany, the Walkill through its whole 

 extent, and the western streams and lakes from Wood Creek to the Oneida 

 Lake, and so on." 



Dr. J. E. DeKay, in his work on the Fishes of New York, quotes the des- 

 cription of Mitchell, referring the species to the heterogeneous mass he enti- 

 tled Leuciscus ; stating at the termination of the quotation, "it has not yet 

 been my good fortune to meet with (this species.") 



Dr. Storer, in his "Synopsis of the Fishes of North America," quotes the 

 description of Mitchell, and the quotation of DeKay , placing both, with 

 queries, as synonyms of Leuciscus {Leucosomus) pulchellus, Storer. 



Messrs. Baird, Girard, Agassiz and Kirtland make no mention of the species, 

 from a want of specimens evidently, as the description of Mitchell, though 

 meagre in the extreme, mentions certain peculiarities by which the species 

 would be instantly recognized, should bona fide specimens be exhibited. 



The author is indebted to his friend J. Walter Vroom, of Trenton, N. J., 

 for specimens of the species and the remarks upon its habits, quoted in this 

 paper.
