Tomes" places Duncairs Jhdoseris in the gewxxs likizangla, basing 

 "his identification on specimens labeled Rhlzangia sedgwlckl Reuss, 

 from the Gosau, sent to him hy W. Bolsche. As the type species of 

 RMzangla is the A.st7'ea hfevisniina Deshayes,'^ the generic characters 

 must be based primarily upon that species. The Rhlzangia sedgwicM 

 of Reuss may ))elong to Podoseris Duncan without afi'ecting the 

 validity of Duncan's genus. Tomes makes two ol^servations that 

 deserve consideration, namely, that there is asexual reproduction b}' 

 gemmation fi'om l)asal stolons in Podoseris, and that dissepiments are 

 present. Tomes's figures (Plate xiv, rigs. 7 and 8) do not look as if 

 there was budding from stolons, and Duncan, in his reply to the criti- 

 cism of Tomes,'' says: •■' The form is not a social one, and never springs 

 from stolons like Rhizangla.'' Tomes has more recently reiterated 

 his identirication of l*odoseris and Rliizangla^*^ but has not adduced a 

 particle of evidence to show that they are the same. 



1 should like to call attention to Felix's opinion on RMzangia 

 sedgimchl. He leaves it in the genus Rluzangia in his Anthozoen 

 del Gosauschichten in den Ostalpen/ referring the genus to the 

 Astra ngiaceai of M. Edwards and Haime. Most probably the speci- 

 mens of Tomes are wrongly identified, or he has misinterpreted them.

Generic diagnosis. — Corallum simple, cuneiform, or depressed, 

 may be discoid, base narrow. No epitheca. Wall perforate, s^'nap- 

 ticulate. Costal present as the distal terminations of the septa. 

 Septa solid, septal margins dentate (dentations rounded in the type 

 species), septal faces granulate. In cross section the granulations 

 are usually directed inward and hooked. Synapticula out of the 

 thecal ring rare; dissepiments appear to be entirely absent. Colu- 

 mella, strictly speaking, absent. When the more perfect ealices are 

 viewed from above, a narrow furrow is seen to occur in the axis; a 

 thin section shows that lower down in the coralkun the inner ends of 

 opposed longer septa fuse directly across the axis; lateral fusion of 

 the inner septal ends ma\', or may not, be complete in the axis.
