"The conillites arc (li\ idod by imincrous thin tiil»ul;i', which arc close 

 t()^(>thcr and are not hoiizontal, Imt concave upward and l)owl-.shaped. 

 Tlie tabuhe are not reouhir, but arc curved and crumpled, the verti- 

 cal section (Plate xxi^ tig. 8) and the horizontal cross section (Plate 

 XXI, tig. 2) show tlieir irregular form. Prom the tabuljc, short(»r and 

 still thinner partitions originate, which run irregularly. obli([U(dy from 

 one ta])ula to another, joining them together, and tinis forming smaller 

 vesicular spaces. 



" The development of the radial lamelhi^ is very rudimentary. The}^ 

 are ])uilt up of thin spine-like pillars of very uneven height, which 

 stand in luimerous, but in only slightly regular radial row^s on the 

 taliidie. Some of these stand so near together in the same row^ that 

 they fuse; others are so long that they extend through several plat- 

 forms of the tal>uhe, the latter appearing to be spread out between 

 them." 



Ogilvie, in her Korallen der Stramberger Schichten," expresses the 

 opinion that ^tt/Joj>It//l/tn/i and Sf(/lo/)k////(?jj,'<i.s are prol)ably related to 

 the Kui>.sainin'id». kShe says: ^^ Kxpsannnia is, because of the irregu- 

 lar structure and arrangement of the trabecuhv especially remarkable. 

 Pratz has already described a similar irregularity of the trabecule in 

 the Jurassic genera llaplarxa and Diplmwa, also in the recent Cosct- 

 naraea. Also the Triassic genera Styl()j>lnjUHin and Styl<)pliyUopsi>< 

 show in their septal structure great agreement with IJaplarwa, etc., 

 i. e., the single trabecula-meud)ers are separated more and more toward 

 the center of the calice and form there a loose, spongy tissue." 



Volz, in his Korallen der Schichten von St. Cassian in Siid-Tirol,* 

 elevates Prech's StyfopJiyUhnv to famil}' rank, calling them the Sfylo- 

 l>]iyUhhv. He describes a new compound genus, lle,tastri^e(<^'' which 

 he places in that famil}^ and also refers to it Duncan's CyatJioeornid.'' 



This family of the SfyhtpJtyJUdH^ sliow^s some suggestive resem- 

 blances to the simple fungid genera, such as Frechla Gregory. 

 FrecJda^ however, has no dissepiments and a few svnapticula.

Remm'ks. — Freeh, in his Korallen Fauna der Trias,*^ referred Stylo- 

 'pJiylhdii to liis Astraeldpe. and placed it with StyJophyllopsh Freeh 

 (new" genus) in a subfamily, the Styhpliyllinie. He emended StyJo- 

 pkylluiii, as follows: "The corallum forms simple calices, with or 

 without lateral buds, as well as massive stocks, which possess a simi-
