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

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

 lono- as the body. Both in the legs (jf the 4"^ and in those of the 5"^ pair merus and carpus 

 are equally long. 



Immediately behind the tul)ercles on the coxae 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 B.\te's Fig. i'" just 

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