76 A RE-EXAMINATION OF AUSTRALIAN PYCNOGONIDA, 



the ventral side of the cephalon some distance behind it» 

 anterior margin. 



Chelophores have a simple scape with ovoid palm and 

 short stumpy fingers. The hand is turned inwards in front 

 of the moiith. The fingers are provided with many small 

 teeth. The scape and palm possess a number of short hairs. 



Palps are four-jointed. They are much shorter than 

 the chelophores, but extend well beyond the proboscis. 

 The basal joint is short and thick, the next joint longer, 

 the third joint longest. The fourth joint is shorter than 

 the third but longer than the second. There are scat- 

 tered hairs on all the joints, but on the last there is a 

 well marked ventral fringe of setae. 



Ovir/erfi. — ^These are ten-jointed and do not possess a 

 terminal claw. Haswell's description is accurate except 

 in relation to the length of the sixth joint, which is longer 

 than any of the other distal joints. 



Legs. — There is nothing to add to Haswell's descrip- 

 tion of these. 



Cement glands are small and numerous. 

 Male genital apertures occur on all limbs.
