immediately opposite the interval between radius and ulna; in one carpus a rough 
nodule of bone, 54 by 33 inches in diameter, was imbedded in but did not reach the 
surface of the cartilage, in the other the cartilaginous area was defined, but it had no 
ossification, it represented the carpal intermedium. ‘To its ulnar side an unossified area 
represented the ulnare, and from it a cartilaginous projection constituted the pisiform, p. 
Fic. 22.—Pectoral limb, B. biscayensis. 
On the radial side of the intermedium was a mass of cartilage imperfectly mapped into 
areas, the proximal part of which represented the radiale ; the distal part was jointed to 
the metacarpal of the pollex, P, and in one carpus a rough nodule of bone 53 by 4 inches 
occupied it which was doubtless distal carpale,, but in the other carpus it was not’ 
ossified. A prolongation of the cartilage between the intermedium and carpalez was 
possibly a potential os centrale. 
The distal part of the carpal cartilage was also mapped into areas : one associated 
with Metacarpal; represented carpalez, another with Mii carpales, another and larger 
with Miy and My represented carpalias;5. In one carpus the distal carpalia were
