more accurately, the shaft and head present more outwardly than those of 

 the fourth. The proximal, or cuboid facet is narrow anteroposterior^, and 

 is curved, the external side being concave. On the external side just distal 

 to this facet, the bead of the bone expands into a large outward-looking 

 tuberosity, which is separated from the posterior tuberosity by a strong 

 notch. Between it and the head proper, on the anterior face, is a large 

 fossa. The entire form is something like that of the proximal extremity of 

 a femur with head, neck, great trochanter and trochanteric fossa. A some- 

 what similar form is seen in the corresponding bone of Oxymna forcipata. 

 The shaft of the fifth metatarsal, is one-fifth longer than that of the second 

 metacarpal (? 3d) above described. Its direction is straight, but it is some- 

 what curved anteroposteriorly. Its section is subtriangular, the apex ex- 

 ternal. The condyle is narrowed and sub-globular above, and spreads 

 laterally behind, the external expansion being wide and more oblique. 

 The keel is prominent, and is only visible from above (in front) as an angle. 

 The distal extremities of some other metatarsals differ in being flatter at the 

 epiconclyles, and concave between them on the posterior face. The con- 

 dyles are more symmetrical, and are bounded above on the anterior face 

 by a profound transverse groove. Several phalanges are preserved, including 

 part of an unguis. They are all depressed, and with well marked articular 

 surfaces, of which the distal are well grooved, and the proximal notched 

 beloWi The lateral areas of insertion of the tendons of the flexors are well 

 marked on the edges of the posterior faces. An ungual phalange is much 

 compressed at the base. The basal table is well marked, and has a free 

 lateral edge. The nutritive foramen enters above the posterior extremity 

 of this edge. No trace of basal sheath.
