25. Biceps hrachii (hie, figs. 0, S, T) in the gopher has two 

 heads; in this respect it differs from this muscle in the rabbits, 

 ground squirrel and tree squirrel, in which the biceps has only the 

 long or glenoid head. In the gopher and in the rat, however, the 

 biceps also has the coracoid head, as in the human biceps.
