214 PROCEEDINGS OP THE ACADEMY OF 



This appears to be exclusively a Western and Northern species, the only speci- 

 mens of which that we have ever seen are in the Museum of the Philadelphia 

 Academy. One specimen was brought from California by Dr. Gambel. 



This bird is perhaps rather larger than L. sejitentrionalis, and resembles it in 

 robustness of organization, but in colors is more like L. ludovicianus. The white 

 spot on the wing is much larger than in any other North American species of 

 this group, and the inner webs of the secondaries are pure white, with more or 

 less black at the ends of the feathers, and as though the white spot of the 

 primaries was continued on the inner webs of the secondaries. All the tail 

 feathers, except the two middle, are largely tipped with white. This bird is ac- 

 curately described by Mr. Swainson as above cited. 



This bird bears a greater resemblance to Vieillot's figure, referred to above, 

 than any other species of North America. 



Selenidera spkctabilis, nobis. 



Belongs to the same group of species as Selenidera piperivora, (Linn.) Gould, 

 Monograph of Rhamphastidae, second edition, pi. 36, and resembling that and 

 other species of this genus in general colors, but with the bill unusually large, 

 and in form and colors somewhat similar to the bill of Rhamphastos ambiguus, 

 Swainson, Gould's Monog. 2d ed., pi. 5, but much smaller and not so dark 

 colored. Rather larger than iS. joepewora or any other known species of this 

 genus. 



Colors of the upper mandible divided obliquely by a line i-unning from below 

 the nostril to the edge of the mandible, within about one third of its length from 

 the tip. Upper portion and tip of upper mandible light greenish yellow, nearly 

 pure yellow at the tip ; lower portion and the entire under mandible dark 

 fuscous green, lighter at the base. Bill at its base with an edging of black as 

 in some species of Rhamphastos. 



Auricular feathers light yellow, tufts on the sides deep orange yellow; tibife 

 dark chestnut ; under tail coverts scarlet. Head, neck, breast and abdomen 

 glossy black. Upper parts of body, wings and tail olive green, darker and 

 tinged with bluish ashy on the tail. Quills with their outer edges tinged with 

 vellow, and their inner edges yellowish white, which is also the color of the 

 under wing coverts. 



No crescent on the back of the neck nor tips of chestnut on the tail in the 

 present specimen. 



Total length about 15 inches, wing 5^, tail 5, bill from the gape 4, from the 

 nostril to tip of upper mandible 3 J inches. 



Hab. — Cocuyos de Veragua, New Grenada. Discovered by Mr. Robert W. 

 Mitchell, of Philadelphia. Spec, in Mus. Acad. Philada. 



This Toucan presents some remarkable and rather anomalous characters. 

 Though having the yellow auriculars and large spots of this color on the sides, 

 and in fact the usual colors of the species of the group designated Selenidera, it 

 has the bill longer and colored in a manner similar to Rhamphastos ambiguus. 

 In form the bill of this species more strongly resembles that of S. piperivora 

 than of any other bird of this group. There is no crescent of yellow on the 

 back of the neck, nor are the feathers of the tail tipped with chestnut, as is usual 

 in this group. All the known species o? Selenidera are in the Museum of this 

 Academy. This species is rather the largest of the genus. 



A single specimen of this curious bird is in a very interesting collection pre- 

 sented to this Academy by Mr. Robert W. Mitchell, son of its distinguished 

 member. Professor John K. Mitchell, M. D., of the Jefferson Medical College. 

 This collection was made in Veragua, the most northern province of New 

 Grenada.
