(With plate* 2). 



Some time ago Mr. P. J. Buitendgk, who enriched our 

 collections already with many valuable objects, presented 

 to our Museum three excellently preserved specimens of a 

 Cubomedusa, belonging to the genus Chiropsalmus. As far 

 as I know, hitherto only two species of this remarkable 

 genus are described, viz. Ch. guadrumanus {Tamoia quadru- 

 mana), observed by Fritz Muller in the sea near Santa 

 Catharina (Brazil) ^), afterwards also found by Wilson near 

 Beaufort (North-Carolina) ^) and Ch. quadrigatus, based 

 by Hackel upon a single specimen, that was collected 

 by Thallitzer at the coast of Rangoon ^). Unfortunately 

 the last specimen was in an indifferent state of preser- 

 vation, so Hackel was unable to give a detailed description 

 of it; nevertheless I think it elaborate enough to conclude, 

 that our individuals bebng to another species, that, in 

 honour of its discoverer, may be named Ch. Buitendijki.
