Naturgeschichte der Anthozoen im Jahre 1882. (389 



Tribe III. Monauleae. 

 Actiniaria with paired septa, but with only one pair of 

 directive septa. 

 Familie Monaulidae Hertw. 



Scytophorus n. g. Sessile Monaulidae with seven pairs of 



septa and fourteen longitudinal furrows on the wall; the wall 



covered with a tough cuticle; no circular muscle; tentacles 



fourteen in number, of medium size, arranged in a Single circle. 



Sc. striatus n. sp. B. 52° 4' S. L. 71° 22' 0. 150 fd. 



Tribe IV. Edwardsiae. 



Actiniaria with eight septa; among which are two pairs of 

 directive septa, whilst the remaining four septa are not paired; 

 all the septa fumished with reproductive organs; tentacles 

 simple, usually more numerous than the septa. 



Hertwig bestätigt bei Besprechung dieses Tribus die 

 Beobachtungen Andres (s. vorig. Jahresber.) über Edwardsia 

 Claparedii, widerspricht aber der Ansicht, dass die Edwardsien 

 zu den skelettbildenden Tetracorallia im selben Verhältnisse 

 stehen, wie die Actinien zu den skelettbildenden Hexacorallia, 

 eher möchte er Formen, wie die Sicyonis crassa in Ver- 

 bindung mit den Rugosen bringen, welch letztere wahrschein- 

 lich auch paarige Septa hatten. 



Tribe V. Zoantheae. 



Actiniaria with numerous septa of two different kinds, 

 smaller, imperfect, sterile microsepta, and larger perfect macro- 

 septa fumished with reproductive organs and mesenteric filaments ; 

 the two kinds usually placed alternately, so that each pair is 

 composed of a larger and a smaller septum; two pairs of 

 directive septa at the ends of the sagittal axis, one pair con- 

 talning only macrosepta, the other microsepta; only one oeso- 

 phageal groove, corresponding to the larger directive septa; 

 animals usually forming colonies, wall usually traversed by 

 endodermal canals, and having the outside encrusted with 

 foreign bodies. 

 Familie Zoanthidae. 



Zoantheae forming colonies; the individuals of a colonie 

 connected with one another by endodermal canals, which run 

 out from the gastric space at the lower end of each polyp. 



Zoanthus Cuv. pro parte. Verrill. 



Z. sp.? Bermuda. 



Epizoanthus Gray.
