 Variation of a small terminal member of a Meristic Series on 

 becoming penultimate which was predicated especially in regard 

 to Teeth (see p. 272). In Morand's case the interesting feet of th<

 proper to the minimus is commended to the attention of the

Girl : one extra digit on the external side of each hand. The 

 normal little fingers are rather longer than usual and the extra lingers 

 have nearly the same length. Each has three phalanges. Neither of 

 the extra fingers can be moved separately from the finger adjacent to 

 it. In the left hand the extra finger is borne on a supernumerary meta- 

 carpal which lies parallel with the normal metacarpal V. Each extra 

 digit can be opposed to the pollex. In the right hand the extra finger 

 is borne on the enlarged head of the fifth metacarpal. Beraxger, Bull.

Man (parents normal, one brother had six digits on each extremity, 

 six other members of family normal) having an extra digit external to 

 minimus on both hands (Fig. 100) and both feet, in series with the 

 normal digits. 



Left hand: unciform abnormally large, having two articular facets, 

 one for the metacarpal of the fifth and the other for that of the sixth 

 digit. The sixth metacarpal bears a digit of three phalanges of which 

 the second and third were very short. [It does not appear that V was 

 of increased length.] Bight hand : metacarpals normal in number, but 

 the fifth is very thick, having in its peripheral third on the external
