A (S specimen of low development (represented in outline 

 above) shows the remarkable tendency to dimorphism seen in 

 males of various genera of the group. The size is httle less than 

 that of the type specimen, but the cephalic horn is only a third of 

 the length and bifurcated at the end and the thoracic horns are 

 represented by a pair of nodular processes occupying the same 

 position, but showing no indication of the very peculiar form 

 assumed in their fuller development.
