Differs from T. derbianus derbianus and T. d. gigas in both 

 sexes by the horns.

 slender; those of the type exceed any measured pair of 

 T. d. gigas. Spiral twist starts much more on front of fore- 

 head. Anterior crest of this spiral passes round the back of 

 the horns only once, NOT twice as in derbianus derbianus ; the 

 distance between base of horn and second frontal point of the 

 twist is much greater than in either of the other two forms.
