less desrree. The inner maroqns of the hooks are continued for a short distance into the interior 

 of the joint, being here apparently coalesced. 



The fourth lees ag-ree vvith the third and I refer to the Tables. The merus bears o n e 

 small spinule long 0,04 — 0,07 mm. just beyond the middle or quite in the middle of the 

 posterior margin and the posterior margin of the propodus bears 5 — 8 spinules, long 0,08 — 

 0,17 mm., besides those at the distal extremity: the female N° 4 from Stat. 273 makes an 

 exception, the 5 spinules are shorter than usüally, 0,046 — 0,06 mm. long. The dactyli measure 

 two-fifths of the propodus, sometimes they are a little shorter or a little longer, and they are 

 3,1 — 3,33-times as long as wide at their base. In the female N° 10 from Stat. 310 they measure 

 just one-third the length of the propodus and are 2,7-times as long as broad; in this female 

 the ventral hook measures */ 9 the length of the dactylus and appears slightly longer than 

 broad at its base, so that the dactylus more resembles those of Syn. Pococki. In the other 

 more typical specimens the ventral hook measures y iB — V20 tne length of the dactylus. 



The third and the fourth legs are much more setose than those of Syn. Pococki. 



Table A does not only show the variable length of the ova-bearing females, but also 

 the variable size and number of the eggs: in two females from Stat. 310 the eggs are extra- 

 ordinarily large.
