It occurs in the Auhinga also, hut is there much smaller. The desmoguathous structure is seen in its highest development; the palatines being not only soldered, but sending down a keel along their line of union; the interorbital septum is. very d(f(ftne, 'svith hori- zont il lutinor border (a ecneial cbaiactei of the Older except m the Peli- cans) The sternum and shouldei - gii dl<, and the knee, are shown in figs. 504, 502. In the knee-joint, thei'e is a bulky free patella, coexistent with a sh(jrt cne- mial apophysis or rotular process of the tibia, but per- fectly distinct tlierefi'oni, as in Podiceps. The muscles of the legs are as in SvUda. The pterylosis agrees essen- tially with the ordinal ptery- lographic characters, but the plumage is peculiar in cer- tain details. Excepting a few speckled species, and some others that are largely white below, the plumage is glossy or lustrous black, often higldy iridescent with green, purple, and violet tints, commonly uniform on the head, neck, and under parts, but on the back and wing-coverts, where the feathers are sharp-edged and distinct, the shade is more apt to be coppery or bronzy, each feather with well-defined darker border.
