Granted our identification is correct, this species seems to be subject 

 to considerable variations in external appearence, as may be seen from 

 the figures we have given. Weare somewhat in doubt if the individual 

 represented in fig. 5 does not belong to C. tripos var. longipcs Bail. 



Loc. in Japan : Kushimoto in Prov. f _Kii. (T. Nishikawa coll.). 



Other known loc.: Tropical Atlantic between 2g°S. and 48°N., 

 where the species is rather common.
