No. 2.] APHRIZA VIRGATA. 331 
ous “ectocondyloid process” is to be observed; and at the 
extreme end, the oblique and radial tubercles, or condyles, stand 
out with more than their usual boldness, a condition which is 
enhanced by the fact that just above them there exists a fossa 
of some considerable depth. When the bones of this limb are 
articulated, and the arm tightly closed, the head of the radius 
accommodates itself to this latter depression at the distal end of 
humerus. Upon the anconal aspect of this extremity of the 
bone, we also find strong and powerfully impressed grooves for 
the passage of the tendons of muscles inserted upon it, and at 
the shoulder joint, during the life of the individual. 
Neither vadzus nor ulna exhibit any very great degree of cur- 
vature, and as a consequence the interosseous space in the 
articulated arm is not very wide. The latter bone develops 
down its shaft a row of some eight or nine papillz, for the quill 
butts of the secondaries of the wing, a feature common to so 
many of our Shore Birds. Comparatively speaking, the distal 
extremities of these bones of the antibrachium in Aphriza, as in 
all Lzmzcole which the writer has examined, are small, though 
to this fact the Oyster-catcher seems to offer an exception. 
The carpal segments are two in number, as usual, and present 
nothing, either in their size, form, or method of articulation, in 
any way different from what we usually find. 
In the pinion (Figs. 13 and 14), the carpo-metacarpal bone is 
long, large-headed, and with its coalesced shafts straight, and 
more than commonly close together. As a negative character, 
we miss the overlapping process at the proximal end of the mid- 
metacarpal, —an apophysis which characterizes this bone in all 
true Galling. Prominent and upturned, the pollex metacarpal 
supports a phalangeal joint that is clawless; the same being 
the case with the distal phalanx of the digit of the succeeding 
finger. 
Regarding the expanded and proximal phalanx of this last 
digit, it is to be noted that its somewhat narrow blade, although 
more or less scooped out upon either aspect, is never perforated 
as we find it in some of the Lavzd@. Att its further end a little 
process protrudes, against which, in life, the head of its follow- 
ing phalanx plays ; this latter joint being very long and slender, 
as in some Plovers and Sandpipers. The little phalangeal joint 
of the remaining digit is crooked so as to accommodate itself to
