fused 4th and 5th carpalia, and its inner side articulates with the 

 outer centrale. 



The intermedium is imperfectly preserved, but was pretty 

 certainly small. As preserved it lies between the radius and 

 ulna. 



The two centralia are of about equal size. The outer is irregu- 

 larly cubical, and lies between the radiale and ulnare. The inner 

 lies between the radiale, the outer centrale, and the 1st and 2nd 

 distal carpalia. 



There are apparently four distal carpals, but there is good reason 

 for believing that what is apparently the 4th is really the 4th and 

 5th anchylosed. 



The 1st distal carpal is a comparatively flat bone somewhat 

 broader than long, and it gives articulation to the first metacarpal. 

 At its outer and posterior corner there lies a small distinct bone 

 which is unfortunately imperfectly preserved. This may be 

 regarded as a radial sesanioid or prepollex. 



The 2nd distal carpal is a small cubical bone, much thicker than 

 the 1st, and it gives articulation to the 2nd metacarpal. 



The 3rd distal carpal is when viewed from above also small, but it 

 is very thick. It supports the 3rd metacarpal. 



The combined 4th and 5th distal carpalia is a large bone nearly 

 twice as wide as long. It is not so thick as either the 2nd or 3rd. 

 What makes it pretty certain we are dealing with two bones and not 

 one are the following characters : A ridge divides the bone into an 

 outer and inner half, and the bony fibres of the inner half at least 

 can be seen radiating out from the centre of this inner half, and 

 further the two halves have each a distinct group of nutrient 

 foramina. The combined bone supports the 4th and 5th meta- 

 carpals. 



The 1st metacarpal is very imperfectly preserved. It evidently 

 was broad and flat. 



The 2nd metacarpal is a short bone only a little longer than 

 broad. The distal end seems to indicate that the 1st phalanx could 

 be considerably overextended. 



The 3rd metacarpal is nearly twice as long as broad, and the 4th 

 metacarpal is nearly three times as long as wide. 



The 5th metacarpal is comparatively flat and broad. It is less 

 than twice as long as broad. 



The phalanges of the 4 outer toes are almost perfectly preserved. 

 In the 2nd digit the 1st phalanx is comparatively short only a little 

 longer than broad, and it is rather flat. The second phalanx is also
