62 PEOF. p. MABTIN DTJNCAN'S RETISION OF THE 



figured years before tlie letterpress relating to it and the genus 

 is published. Zoologists have long since decided against any 

 such proceeding. The genus dates from the time of reading 

 in or publication by a Society, or periodical, or book. Another 

 method is more remarkable, and consists of diagnosing genera 

 the species of which have not been found. 



Stephanosmilta, jE/. de ^romentel, Fal. Frang., Terr. cret. (non 



Beuss), t. viii. Livr. 22, p. 242, 1867 (pi. 26, date 1862, without 



letterpress). 



Corallum trochoid and pedicellate. Wall naked. Costse well 

 developed, nodular. Columella fasciculate. Septa exsert. Pali 

 well developed, and placed before the septa of the first two cycles. 

 Endothecal dissepiments rather distant. 



Distribution.— Fossil. Grault : Europe. Eocene : Borneo. 



M. de Eromentel really published the genus in 1867, having 

 figured it only, five years before. He placed it at first amongst 

 styliform columellate TrocliosmilicB. 



Steplianosmilia, Eeuss, is a synonym of TrocliocyatJius. 



The following genus is thoroughly Australian in its strangeness. 



G-enus Cyathosmtlia, Tennison Woods, Trans. Fhil. Sac. Ade- 

 laide, 8. Australia, 1877-78, viii. p. 113. 

 Corallum simple, pedicellate. Calice elliptical. Columella 

 absent. Pali present. Costae exsert. Endotheca plentiful. 

 Distribution. — Fossil. Australian Tertiary deposits. 



Tribe II. 



Genus Pattalophtllta, d'Achiardi, Mem. della Soc. Italia di 

 Sci. Nat. Milano, torn. iv. no. 1, 1868, p. 3. 



Corallum simple, free, cornute. Pali before the antepenulti- 

 mate cycle of septa. Columella absent. The septal laminae 

 finely and regularly denticulated. Endothecal dissepiments not 

 very abundant. 



Distribution. — Fossil. Eocene: Europe. 



The figures given by d'Achiardi in vol. ii. no. 4 of the above 

 work show a coral with a narrow pedicellate end, curving and 

 swelling to the long elliptical calice. The costse are seen ; and 

 there is no epitheca. The pali form a crown of lobes within the 

 septal edges, and there is no columella.
