I AM indebted to Mr J. Graham Kerr for the opportunity of 

 examining some cases of abnormal limbs in Lepidosiren paradoxa 

 obtained by him in the Paraguayan Chaco. The specimen now 

 shewn and these sketches of the limbs of others shew the unusual 

 condition to be either partial duplicity of the limb or else a 

 sudden tapering into a sharp tip. Mr Kerr informs me that 

 among 26 adult individuals examined he found two cases of partial 

 duplicity, and it seems certain that this condition is of fairly 

 frequent occurrence, while the sudden sharpening of the tip is still 

 more common.

 branching than any which are illustrated here. The branches
