D. BRYCE ON THE MACROTKACHELOUS CALLIDIN^. 23 



ceedingly timid and would scarcely extend itself, far less com- 

 mence feeding. The cuticle was dense, and I could not get at 

 internal details, nor could I count with certainty the number of 

 teeth on each ramus. When extended it had rather the outline 

 of a Philodiiia, but I could not detect any eyes. As the head 

 and neck were protruded the lateral s^Dines became depressed, 

 falling close to the sides. The spurs have a distinct re- 

 semblance to the toes of TapJirocampa selemcra, and were each 

 nearly i-^q^ of an inch in length, that of the whole animal ex- 

 tended beinoc estimated at about -^— of an inch.
