Extetisor indicis. — Arises from the posterior border of ulna and 

 from expanded olecranon. It divides into two tendons which go 

 to the second and third digits. This muscle is not mentioned by 

 Coues as distinct ; he describes an abortive slip of communis as 

 probably representing aii indicis. In my specimen indicis was a 

 most distinct separate muscle, situated on a deeper plane than 

 extensor communis.
