Dtdr'dxiilou. — Older Tertiarie.s of the Antilles. 



Remarks. — Duncan referred tlie corals for which I am proposing 

 AntlUoserh to his Turhinoserh.^^ but it seems probable that Turhino- 

 seris is a S3'nonym of LeptoplujJlla Reuss. As will be pointed out later, 

 Turlnnoseris has never been properly defined (see p. -fli>). Rather 

 than leave the West Indies species in the uncertain state in which they 

 have been for many years, I have erected a new genus for them. 



Antilloseris is very closely related to Podoserix Duncan. The 

 former differ from the latter (1) by being- devoid of epitheca, (2) by 

 the absence of dissepiments, (8) V>y the absence of a columella. Podo- 

 seris appears to possess a small, ]>ut papillate columella.

 onymy given by Gregory on p. 161.) 



Diagnosis of the family. — Simple or colonial Fungids, in which 

 the septa are perforate lamellae; perforations exist principally near 

 the top or the inner ends of the septa, the pores below filled with 

 stereoplasm. 



I have placed nine of the described genera in this famil} , namelv: 

 Gyroserls^^\\A%., Leptophyllla Reuss, //«/>Z(?re'ft'(^ Milaschewitz, Proteth- 

 raos Gregory, Metethtnos Gregory, Frechia Gregory, liacoseris de 

 Fiomentel, Llthoseris Koby and ProcycloUtes Freeh. I have appended 

 under the heading "Septa as in Leptophylllidx ; condition of wall 

 unknown," Myriophxjllia Volz, (hnp>lialop>hyUia Laube and Craspe- 

 dophylUa., subgenus, Volz. 



I think it very probable that the number of these genera will be 

 considerably reduced.
