from Stat. 316, the legs of the 5'^^ pair measure three-fourths the length of the whole body, 

 whereas, according to Alcock, in full-grown specimens long 85 mm. these legs are at least as 

 long as the body. Both in the legs of the 4''' and in those of the ^^^ pair merus and carpus 

 are equally long. 



Immediately behind the tubercles on the co.Kae of the 3"' pair of legs, the females captured 

 by the "Siboga" bear a transverse vertical plate with a rather sharp upper edge, but 

 which barely can be said to have a crescentic or lunate form ; the flattened, median, sternal, 

 shield-shaped tubercle between the legs of the 5"' pair appears in Spence Bate's Fig. 1'" just 

 as long as broad, in all our females, however, distinctly broader than long.
