ninth and thirteenth (usually tl nth) is oblong, and the following quickly become triangular, 



is long as broad. 



rhe first four brachials have a low very broadly rounded median carination which is 

 very obscure; the following have an equally obscure slight very broad cönvexity in the middle 

 of the dorsal surface which after the eight or ninth becomes smaller in area and resolvés itself 

 into a low rounded tubercle witch gradually disappears after the end of the proximal third, 

 though it may be detected as far as the end of the proximal half. 



The ornamentation of the smaller specimen is similar, but the tubercles on both elements 

 of the IBr fhtly narrower so as to appear as a broadly rounded carination.
