598 Leuckart: Bericht üb. d. wissenschaftlichen Leistungen 



sind die zwei erstgenannten, auf welche Verf. unter dem 

 Namen Turbinolidae reptantes eine neue Subfamilie mit fol- 

 gender Diagnose gründet: Corals rising from a Prolongation 

 of the basal structures, sometimes distant, sometimes very 

 close; the septa are piain; and there is no endotheca. 



Gen. n. Platycyathus Dune, e Fam. Turbinol. An epitheca 

 covering the costae; pali are present; the columella is usually deeply 

 seated. 



Gen. n. Agelacyathus Dune, e Fam. Turbin. No epitheca, 

 nor endotheca; the costae well developed, especially near the calices; 

 septa more or less exsert; pali and columella present. 



Gen. n. Javania Bunc. e Fam. Turbin. Corallum simple, tall, 

 compressed at the calyx, adherent by a broad base; epitheca com- 

 plete, dense inferiorly, pellicular superiorly, large septa very exsert, 

 primary and secundary costae projecting; no columella; calicular 

 fossa very deep. 



Gen. n. Brachytrochus Dune, e Fam. Turbin. Corallum 

 short, free or incrusting (on Annelid shells), calyx circular; deep 

 centrally; no columella; septa exsert papillose; costae well developed, 

 merging into a granulär structure on the rounded centre of the base. 



Gen. n. Dendroeora Dune, e Fam. Cladocor. Corallum 

 bushy, branches short, frequeutly forming groups in one plane; 

 wall thick, except near the calices ; costae distinct, thicker than 

 the septa; collumella lax and trabecular; pali placed before the 

 tertiary septa in perfect Systems; fissiparity common in the terminal 

 calices, presenting short broken series; no epitheca; endotheca tole- 

 rably abundant. 



Caryophyllia polygona, Faracyathus floSj Thecocyathus 

 recurvattis, Ceratotrochus hispidus, Turhinolia corhicula, 

 Amphihelia rostrata, Änthemiphyllia (n. gen.) patera, 

 Montivaultia poculum^ Colangia sitnplex, Cylicia inflata, 

 Balanophyllia pali f er a, Trochopsammia infundibulum^ sämmt- 

 lich neu, aus der Tiefe des Mexikanischen Meerbusens werden 

 vonPourtales (1. c. 198 — 208) beschrieben und theil weise 

 abgebildet. Das neue Genus hat folgende Diagnose: 



Änthemiphyllia Pourt. Corallum free or pedicellate, with 

 rudimentary epitheca, no collumella; thick and having the edge 

 beset with transversaly flattened processes. It is allied to Lepto- 

 phyllia and Montivaultia, but differs from them by the mode of 

 division of the border of the septa, which in these generally consists 

 in simple spines.
