A metacarpal bone, probably the second, is quite short, and the shaft is 

 contracted, and the distal end expanded. The proximal extremity has the 

 facet slightly concave, and with the posterior edge broadl}^ rounded, and a 

 little raised, and with a narrow lateral facet on each side. The one of these 

 slopes outwards below; the other inwards to an open excavated surface. 

 The shaft is slightly convex in front, both in length and width. The distal 

 condyle is flat and truncate, and is not bounded by a groove pi-oximally. 

 The keel is distinct but not strong. The condyle is truncated by a round liga- 

 mentous fossa on each side, and a wide transverse one posteriorly proximad. 

 There is a fossa of the anterior face just below the proximal facet; and 

 there is an open groove on each side proximally, below the lateral facets, 

 which are not cut by them. 



Some fragments of metajoodials and some phalanges are preserved 

 which may belong to the manus or pes. The phalanges are those of the 

 middle place. Their outlines are nearly square, the narrowing distally de- 

 stroying its regularity. They are quite depressed, and the proximal coty- 

 lus looks partly upwards. The lateral distal ligamentous fossae are round, 

 and impressed. The lateral border proximad to them is a narrow ridge. 

 The distal condyle is not produced posteriorly, but extends posteriorly and 

 is cut off by a rather shallow fossa. An ungual phalange is quite flat, but 

 not much expanded. The distal extremity is deeply fissured above. The 

 inferior table fades out distally; its proximal lateral angles are bounded by 

 fossse, two of which are, perhaps, foramina. There is a short free angle on 

 each side of the proximal cotylus. The superior surface is longitudinally 

 roughened on each side of the median groove.
