of anterior tarsi longer than those of the two posterior pairs : middle and 

 posterior pairs, femora four-angled, narrow above broad and flat below with 

 spines on all four edges ; of the middle pair the femora and tibias are of equal 

 length, 7 lines long, with an elevated spine on the outer edge of the tibia3 at the 

 upper end : posterior pair, femora and tibia? also of equal length, 8 lines long.

Obs. I may also note that this specimen had lost its anterior left leg, 

 and that a new one was growing to replace it. This new leg is very small 

 and slim, less than 1 inch in total length, but agreeing in all minute par- 

 ticulars with the right one, save that its more salient points were not fully 

 developed. I suspect this loss of limb is a matter of rather common 

 occurrence among the Bacilli, — from the great length of their slender legs, 

 their habitat among the green leaves of trees in the exposed windy 

 branchlets, and their known fighting and cannibal propensities. I have 

 already noticed an instance of similar mutilation, in my description of 

 B. sylvaticus (Trans. N.Z. Inst., vol. xiv., p. 278).
