78 A RE- EXAMINATION OF AUSTRALIAN PYCNOGONIDA, 



mouth. Both fingers are wide, blunt, and untoothed. but 

 bearing on each inner edge a single central rounded pro- 

 jection. 



Pal%/s are absent. 



Ovigers possess ten joints and a claw. First joint is 

 short, second, third, and fourth are progressively longer. 

 Fifth joint is long curved and slender, distally expanded 

 with a peg like p^rocess at this end, thei procesis being 

 crowned with a number of short setae. Sixth joint is short, 

 and the seventh, eighth, ninth, and tenth are progressively 

 shorter. The last four joints are provided with a few bent 

 compound spines arranged in a single row. The terminal 

 claw is long and sharp and is ornamented with fine teeth 

 on the distal half of its inner edge and on the distal third 

 of its outer edge. 



Legs. — The first and third coxee are short and sub- 

 equal. The second is as long as the other two together and 

 is distally expanded. The femur is a long joint a little 

 longer than the combined coxge. The first tibia is a little 

 shorter and expands distally. The second tibia is a little 

 longer than the femur. The femur, first tibia, and second 

 tibia are approximately divided into thirds by shallow 

 transverse constrictious. All these joints are minutely 

 spinous. The tarsus is short with a very small dorsal spine 

 and a bunch of closely crowded ventral spines. The j)ro- 

 podus is very stout, minutely spinous. On the sole, 

 proximally, there are some four or five well developed 

 spines. The distal half of the sole has smaller spines. The 

 claw is large, stroug, and curved, and is equal to more 

 'than two-tlairds the length of the propodus.
