besides those at the distal extremity. The dactyli very much resemble those of Syn. neómeris\ 

 they measure a little less than one-third the length of the propodus, viz. 4 /is ar >d they are just 

 2,5-times as long as broad near the articulation ; the acuminate ventral hook, which measures 

 almost half the length of the joint and which is 3-times as long as broad at its base, is 

 obliquely directed forward like in Syn. neomeris\ the length of the dorsal hook is one-third 

 that of the other, which is 3-times as thick at its base as the former. 



The proportions of the fourth pair are: merus 2,32; carpus i; propodus 2,1. Merus 

 3,27-times longer than wide, with one spinule, long 0,1 mm., of a stout shape just beyond 

 the middle; carpus twice, propodus 5-times as long as broad, the propodus also with four 

 spinules long 0,11 — o, 16 mm., besides those at the distal extremity. Dactylus just one-third the 

 length of the propodus, 2,4-times as long as wide near the articulation, for the rest fully 

 resembling that of the third pair. The third and the fourth legs are moderately setose. 



Length of the single specimen 16,5 mm.
