and Tendons of a Toe, of the Foot of Dinornis robustus, Ow. By Professor

[Pirate LX XXVIII. } 
THROUGH the liberality of the President and Council of the Philosophical Society 
of York I have been favoured by the transmission, for examination and description, of 
the portion of the foot, with the adherent tendons and integument, of the skeleton of 
the Moa, referred to in the letter of Dr. Hector, F.G.S., quoted in a former Memoir 
(Part IX.)', which skeleton, having been transmitted to the Museum of the Philoso- 
phical Society at York, I determined, and referred, in that Memoir, to the Dinornis 
robustus. 
The toe, so preserved, with the tendons, sesamoids, and tegumentary sole-pads 
(Pl. LXXXVIITI.), is the inner one (7) of the right foot, and includes the three pha- 
langes, corresponding in size and character with those figured in the Memoir 
(Part IV.)?. 
To the outer side of the proximal end of the first phalanx the capsule of the joint 
adheres (Pl. LXX XVIII. fig. 1, ¢), whence it is continued upon the same side of that 
part enclosing the metatarsal trochlea, and is extended upon the upper part of the 
sheath of the tendons and sesamoids (s, ib. a, 6, ¢) beneath the joint between that 
phalanx and the corresponding (innermost) trochlea of the tarso-metatarsal. Part of 
the dried cartilage also adheres (at f') to the proximal articular surface of the phalanx. 
The terminal portions of the tendon (a), inserted by means of the sesamoids and 
their ligament into the base of the first phalanx, part of the perforating tendon (4), 
similarly inserted into that of the second phalanx, and part of the upper perforating 
tendon (c), which is continued to that of the last phalanx, are here preserved. 
The largest portion of the sole-skin includes the pad (ib. fig. 2, dd’) beneath the 
trochlear division of the metatarse answering to the above toe, with part of that which 
extended beneath the middle trochlea, but wanting the outer portion. The under 
surface of so much as remains of this ‘‘ heel-pad” measures 3 inches 8 lines by 3 inches 
6 lines. 
The margin (d' d') towards the missing outer heel of the pad shows abrasion; but 
where the under surface is entire, it is beset with large papille, having a tendency to a
