BOHEMIAN WAXWING.

AMPELIS GARRULUS. 

 Bohemian Waxwing. 



Ampclis gaiTulus Linn., Syst. Nat. 1, ITGC), iiJ". 



DESCRIPTION. 



Sp. Ch. Form, similar to that of the Cedar Bird, but tlie size is larger and the general coloration is 

 similar, but differs in having the throat abruptly black, the forehead and sides of head chestnut : the color 

 beneatli is paler but without any .yellow, the under tail coverts are chestnut; the secondaries edged on outer 

 web near tips with white, and the primaries with yellow or white. 



OBSERVATIONS. 



During the winter of ISISO I received some fifty specimens of this s]>ecies, in the flesh, from Mexico, 

 N. Y. and Clayton, Minn., and was thus afforded an e.xcellent opportunity of examining the vocal and 

 other organs. 



As I knew it to be a mooted point among ornithologists as to whether the IJuhemian Waxwing is capable- 

 of uttering anything like song, it was with cunsideralile interest that I examined the inferior larynx.

The sterno trachealis is present, but it is not only reduced to a mere transparent thread, but has no- 

 sternal attachment. This muscle has its tracheal origin, as in all of the true singing birds that I have- 

 examined, below the division of the broncho trachealis, which muscle is present and well developed, from 

 thence the stemo trachealis proceeds upwards, at a slight angle backward, and becomes firraly attached to 

 the muscles of the neck. 



This arrangement can be seen at Fig. (iO ; t, being the trachea, b, the broncho trachealis, m, the lungs 

 from which emerge the bronchial tubes : e, e, represents a jwrtion of the neck to which the short sterno 

 tracheal muscle adheres, n being the right, and u the left of these. All three of these figures are life size. 



Although it is not unusual for the lower larynx to receive support from filamentous tissues which are 

 attached to the neck, this is the only case that has come to my knowledge where the stemo trachealis is so 

 attached. 



Owing to its point of attachment, this muscle must be ((uite functionless so far as being an aid toward 

 producing sound, thus we are not surprised upon examining the bronchial tubes to find that there is no- 

 tympaniform membrane. The bronchial rings, although extending round the tubes, are not entire, but there- 

 is a narrow division on the inside in the place usually occupied by the t\ mpaniforms. I also find that the-
