CIIIROPSALMUS BUITENDIJKI. 105 



meauing; perhaps the embryology afterwards will throw 

 some light upon this question, but presently I can only 

 state that they are in connection with the reproductive 

 system. For each stomach-pocket contains a pair of the 

 leaf-like reproductive organs (fig. 2, ro), that are 

 attached to their interradial border; these leaves, that are 

 nearly triangular shaped and partially folded, do not reach 

 laterally the perradius and extend downward till on a short 

 distance above the frenula. But they extend them- 

 selves into the pocket-arms and produce the 

 folded appearance of these organs. The examined 

 specimen was a male. 



1 do not think that our specimens can be identified 

 with either of the two species already described. 



By the following table the three species may be distin- 

 guished : 



A. Umbrella bell-shaped, almost semiglobular. 

 Pedalia with 10 to 11 



branches Chiropsalrnus quadrimianus Mull, 



(East-coast of America). 



B, Umbrella nearly cuboid, arched above. 

 Pedalia with less as 10 branches. 



a. Pocket-arms ovoid, 



hardly a fourth of 

 the length of the 

 lateral pockets. 

 Pedalia with 4 

 branches Chiropsalrnus quadrigatus Hack. 



(Coast of Rangoon). 



b. Pocket-arms finger- 



shaped, nearly as 

 long as the lateral 

 pockets. Pedalia 

 with 5 to 6 bran- 

 ches Chiropsalrnus Buitendijki, u. sp. 



(Road of Batavia).
