Note on the Manns of Procoloi)lion.— ]>y R. BROOM, M.D., &c. 



In part 1, vol. 1, of the Records of the Albany Mnseum, page 

 19, I stated that "there are four phalanges in the 5th digit." This 

 is incorrect. A specimen of apparently a new species of Procolo- 

 plion has recently been acquired by the South African Museum, 

 and on being developed was found to present the almost perfect 

 left manus. The true digital formula was then seen to be 2, 3, 4, 

 5, 3, as in all other known Diapsosaurians. A re-examination of 

 the Albany Museum specimen also shows that the phalanx which 

 I believed to be the penultimate is really the terminal. 



Prof. H. F. Osborn, in his recent paper on the Diapsosauria 

 (Mem. Am. Mus. Nat. Hist., 1903), suggests that the carpal element 

 which I regarded as the radiale is really a centrale. The carpus 

 certainly has the appearance of having lost the radiale : but in 

 none of the three carpi which I have examined have I been al)le 

 to hnd a radiale in addition to the element which lies between 

 the 1st carpale and the element which is undoubtedly a centrale. 

 If I am wrong in regarding this element as tlie radiale, tlieu it 

 would seem that the radiale has been cartilaginous.
