The central tail-feathers are long-exserted, and spatulate by absence of webs along a part of the shaft - a mutilation effected, it is said, by the birds themselves; the bill is about as long as the head, gently curved; the nostrils are rounded, basal, exposed; the wings are short and rounded; the tarsi are scutellate anteriorly. It is greenish, with blue head." Elliot Coues, 1884

"Spermatozoa of domestic cock, greatly magnified." The spermatozoam or seminal animalcules, or male Dynamamaebae (figs. 106, 107), are the exact counterparts of ovarian ova, in so far as they are single-celled animals of a very low grade of organization; but their activity and intelligence is marvelousm and still more so is the mysterious attribute with which they are endowed of assimilating their protoplasmic substance with that of the ovum; with the result that thus fecundated ovum is capable of procreating itself by fission for a period until a mass of similar creates in engendered; from which mass is then speedily evolved the complex body the bird."

Drawn by Dr. R. W. Shufeldt, USA, After Owen. The Axial Skeleton of a bird or any vertebrated animal, that is, one having a back-bone, exhibits in cross-section two rings or hoops, one above and the other below a central point, like the upper and lower loops of a figure 8. The upper ring is the neural arch, so called because such cylinder encloses a section of the cerebro-spinal axis, or principal nervous system of a vertebrate (brain and spinal cord, whence arise all the nerves of the body, excepting those of the sympathetic nervous system). The lower ring is the haema arch, which similarly contains a section of the principal blood vessals and viscera.

'Rhynchops. Skimmer. Bill hypognathous Among the singular bills of birds that frequently excite our wonder, that of the skimmers as one of the most anomalous. The under mandible is much longer than the upper, compressed like a knife-blade; its end is obtuse; its sides come abruptly together and are completely soldered; the upper edge is as sharp as the under, and fits a groove in the upper mandible; the jawbone, viewed apart, looks like a short-handled pitchfork. The upper mandible in also compressed, but less so, nor is it so obtuse at the end; its substance is nearly hallow, with light cancellated structure, much as in a toucan; it is freely movable by means of an elastic hinge at the forehead."

"Desmognathous skull of mallard duck, Anas boscas, nat. size, from nature, by Dr. R.W. Shufeldt, U.S.A. Letters before. In the "bound-palate" type, the vomer in either abortive, or so small that it disappears; when existing it is usually slender and tapers to a point in front; the maxillo-palatines are united across the median line, either directly or by means of ossification in the nasal septum; the posterior ends of the palatines and the anterior ends of the pterygoids articulate directly with the rostrum (as in schizognathism). This type is simply and perfectly exhibited by a duck in which the maxillo-palatine is a broad flat plate united with its fellow in mid-line; the oval sessile basipterygoid facets are far forward, opposite the very ends of the pterygoids."
