onychaster (figs. 14, 16). The said variation in the development 

 of terminal discs occurs irrespective of the rosette beiug normally 

 developed, hemihexactinoso or hexactinose. In certain cases I 

 have found the terminal claws branched (fig. lö). 



SYMPAGELLA O. Schm. 



SynipageUa, O. Schmidt, '70, p. 15. — F. E. Schulze, 



'86; '87; p. 119; '97, p. 528; '99, p. 

 32; '00 a. 



Aulascus, F. E. Schulze, '86; '87, p. 118; 97, p. 527. 



Caulophacids of cup-like body, showing tendency to form 

 small colonies by budding. Parenchymalia as in Caidophacus. 

 Dermalia, either hexactiiiic or pentactinic pinnies. Gastralia, 

 hexactinic pinnies. Besides discohexasters, strobiloplumicome 

 always present. 



The new species to be presently described under the name 

 of SympageUa anomala niight, apparently with equal propriety 

 be referred to the same genus as Aulascus johnstoni F. E. Sch. 

 In fact, it appears to me that the genus Aulascus is scarcely 

 sufficiently differentiated in characters to justify its separation 

 from SynipageUa. Hence I have placed it under the synonymy 

 of the older name O. Schiniidt's in spite of F. E. Schulze's 

 ('97) opinion to the contrary. It seems to me fairly assumable
