in front of the fascia tendinea of the arm. (In Psittacus 
magnuSj Linn., the first of these is seated upon the fascia 
itself.) 
The Raptorial birds have most frequently three series 
seated upon the underside: the first consists of large, and 
the last of very small or quite rudimentary feathers. In 
Strix liturata and Falco subbuteo, however, I found only one 
large, and one nearly rudimentary series. 
Among the Gallinse the species of Tetrao have three defi¬ 
nitely developed ulnar series (fig. 4, q, 1, 2, 3), and two 
or three nearly downy, small radial series. 
Fulica has only the three rows on the ulnar surface formed 
as in Tetrao; Ciconia nigra scarcely more than two. Nu- 
menius and Scolopax have on the ulnar surface one moderate 
and one very small series; and on the radial surface one 
small and one rudimentary series. 
In the Fuligulee {spectabilis, glacialis) there are three series 
behind the fascia, namely one of middle size close upon the 
reversed feathers, and after this two series of very small 
feathers, which are placed alternately, but so close together 
that they seem almost like a single one; and, finally, three 
distinct radial series in front of the fascia. Sterna hirundo 
has only the three first-mentioned. Podiceps possesses only 
one series behind and one before the fascia; Uria grylle , on 
the contrary, has a pretty large one behind and three small 
ones in front of the fascia. 
On the lower surface of the hand itself there are from 
three to four irregular series of short, rounded, and adpressed 
feathers, which closely cover this part, as on the outer sur¬ 
face (figs. 4 and 8, r). 
3. The tectrices ant e cubit ales inferior es or inframarginales, 
the lower marginal feathers of the wing ( s) } clothe the 
underside of the great fold of skin between the humerus and 
cubitus. In general they only form two or three series, 
situated beneath the margin itself, so that the greater part 
of the fold of skin is destitute of feathers, or has nothing but 
down. In all birds they are in all respects right-lying or 
onposite to the remiges. Thus they show the right side, and
