96 TWO NEW AUSTRALIAN PYCNOGONIDA, 



any of the trunk eminences, with well marked visual 

 elements, anterior pair a little larger than the posterior. 



Proboscis hasi tlie^ form and appearance' associated with 

 many of the members of this genus. Its shajoe is roughh'" 

 that of a long ellipse, the narrow end of which is inserted 

 moveably into the ventral side of the cephalon. At about 

 one-third the distance from its: proximal end there is a 

 shallow transverse groove running circularly round the 

 proboscis. In front of this, the proboscis expands greatly 

 and then contraicts, ending in a rounded anterior ex- 

 tremity. 



Ghelifori short, a little less than one-third the length 

 of the proboscis ; scape smooth and one-jointed, chela re- 

 duoed to a single terminal joint. 



Paljji loinger than proboscis, nine jointed, first joint 

 small, sieoond very long, third a little longer than the 

 first, fourth joint is about equal in length to the second 

 but is a little stouter and slightly curved, fifth is shorter 

 than ih.Q fourth but longer than the third. The remaining 

 joints are all small, but the sixth is the longest. All 

 joints are smooth. 



Ovigers. — These are damaged as mentioned above, 

 there being only the basal three joints and part of the 

 fourth joint left. First joint is much swollen and of mod- 

 erate length, the second is longer, narrow and curved, 

 the third is shorter than the second and is also somewhat 

 curved. 



Abdomen semi-erect, rising from the posterior border 

 of the penultimate trunk segment ; its base is expanded 

 and is very little less in width than the segment of the 

 trunk. The abdomen narrows and again expands fusi- 

 formly, ending in a rounded extremity. In side view it 

 presents the appiearanoe of a tube of somewhat even 

 diameter. 



Legs. — Owing to the loss of the third leg on each side, 

 the custom which has. been adhered to by most writers, 

 of describing and measuring the third leg of the right 

 side, cannot be maintained in this- case, and so the 

 measurements here given will refer to^ the second right 

 leg. 



The first coxa is squarish and slightly expanded dis- 

 tally. The second coxa is more than twice as long as 

 the first and is slightly curved. While it is expanded 

 ao the distal end it is not so stoiut as the first coxa. The 

 third coxa is short and thick, a little longer than the first 

 coxa. The armature of the coxal region shows notJiins:
