3. Genus ASTEROSERIS cle Fromentel. 



1867. Aderoiievh de Fkomentel, Palrontol. frant;., Cretace, VIII, Zoopli., Pt. 24, 

 p. :528. 



( h-ignud <j('nerie dlfujno.'^h. — ''The coralluin is hemispherical, basal 

 wall impei'forate, discoid, slightly concave and covered with granula- 

 tions, which are radially arranged on the margins. The columella ))ut 

 slightly developed, reduced to three or four scarcely visible points. 

 Septa large, unequal, strongly granulated on their upper margins. 

 Pali well developed.'' 



Tiijje species. — Asteroserls coronuJa de Fromentel, Paleontol. frany., 

 Cr^tace, VIII, Zooph., Pt. 24, p. 328, pi. xlviii, tigs. 3-3c. 



Disfr/hut/'on. — Neocomian of Mans, Prance. 



ReiiKirl's. — By a mistake, the name is given at the Ijottom of Plate 

 XLVIII (which was published in Livraison 12) as Stejfhanoseris. 



De Fromentel does not describe the structure of the septa. It can 

 only be inferred from the character of the septal margins — such an 

 inference, of course, is doubtful. 



II . SEPTA SOLID, CONDITION OP WALL UNKNOWN. 



Zittelofungia. 



Genus ZITTELOFUNGIA Duncan. 



18(S4. Zitielnfnrigur DrxcAN, Jour. Linn. Soe. London, Zool., XVIII, p. 150. 



Orhjindl (jrnei'ic dhajnosh. — "Corallum free, plano-convex, circular 

 or elliptical in outline, with a flat or slightly concave base, and a con- 

 vex calice with a circular or oval fossa. Columella absent. Septa 

 very numerous, close, thin, unequal, uniting, crested denticulate or 

 moniliform at the free edge, granular at the sides, imperforate. 

 Synapticula numerous. Dissepiments wanting. Epitheca of base in 

 concentric folds, stout or thin. 



'"''Distr'dndhm. — Fossil. Eocene: Sind." 



Duncan in his Sind fossil corals and Alcyonaria, pp. 52-55, 

 describes nine species which he refers to CycloUtes, namely: C. alpina 

 (d'Or])igny), C. ranihotl Duncan, C. cremdata Duncan, C. mcaryi 

 Haime, C. cmomala Duncan, 6*1 superba Duncan, G. hahaei Duncan, 

 61 altnvillensis Defrance, and 61 striatd Duncan. Duncan separated 

 these corals from Cydolites because of their imperforate septa, and 

 proposed for them the generic name Zittelofungia. But no type spe- 

 cies was designated. The septal structure of not even one of the 

 species is described. Whether it is the same for all can be determined 

 only from an examination of his original material. Until this is done 

 a type species that will tit the original generic diagnosis can not be 

 selected with certainty. 



III. WALL PERFORATE, CONDITION OF SEPTA UNKNOWN. 



Cyclabacia.
