Dr. R. Schifer—On Phillipsastreea, d Orb. 399 
In the year 1850 Messrs. Edwards and Haime’ mentioned the 
genus Phillipsastrea; the genus Smithia was not established at that 
date. Their diagnosis of Phillipsastrea contains the words: ‘The 
centre of the tabule presenting a columellarian tubercle.” As the 
type species they mention Phillipsastrea Hennahii, Lonsd. (= Astrea — 
Hennahii, Lonsd., in Geol. Trans., 2nd ser. vol. v. pl. 58, fig. 3). 
This is of importance, as in the following year this very species 
became the type of the genus Smithia. 
In the year 1851 Messrs. Edwards and Haime established the 
genus Smithia:* “‘ Smithia. Polypier ayant la méme structure que 
les Acervularia, mais manquant de murailles extérieures distinctes 
et présentant des rayons septo-costaux plus ou moins confluents,” 
and (loc. cit. p. 421): ‘“ Pas de columelle.” Type species: Smithia 
Hennahii (= Astrea Hennahii, Lonsd.), the same species which in 
1851 was the type of Phillipsastrea. The following species of 
Smithia are given: Smithia Hennahii, Lonsd., Smithia Pengellyi, 
E. & H., Smithia Boloniensis, E. & H., and Smithia Bowerbankii, 
HK. & H. 
In the diagnosis of the genus Phillipsastrea we read (Mon. des 
Polyp. Foss. p. 173): ‘‘ Phillipsastrea. Polypier présentant la 
méme structure que les Smithia, mais ayant une columelle styliforme,” 
and (loc. cit. p. 447): “Les Phillipsastrées different des Smithies 
par la présence de leur columelle.” Type species: Phillipsastrea 
radiata, S. Woodw. The following additional species are mentioned : 
Phillipsastrea Vernewili, H. & H., and Phillipsastrea tuberosa, M‘Coy. 
In the diagnosis of the type species Phillipsastrea radiata (loc. 
cit. p. 448) we read: “columelle mince et comprimée, en général 
peu distincte;” the figure (Brit. Foss. Cor. tab. 37, fig. 2) shows 
no columella. In the description of Phillipsastrea tuberosa, (loc. 
cit. p. 449) Messrs. Edwards and Haime do not mention any 
columella, neither does M‘Coy.? Further, the figures given by 
M‘Coy* do not present, either in the transverse section or on the 
surface, any indication of a columella. In the diagnosis of Phillips- 
astraa Verneuili (loc. cit. p. 448) Messrs. Edwards and Haime say: 
“columelle saillante”; the figure (Mon. des Polyp. Foss. tab. x. 
fig. 5) shows the same clearly, but only on the surface, since a 
transverse section is not given. 
Kunth® has already explained all that has been mentioned so 
far. He has also given (loc. cit. p. 30, and tab. i. fig. 4) an 
exact description of Phillipsastrea Hennahit, Lonsd. ( = Smithia
