Duncan publishes the following: 
"A variety of this species is present in the St. Bartholo- 
mew limestone; and it has a very great resemblance to the type 
which came from Oberburg, in Styria, and was described by Reuss 
(a) 
in 1864."

Reuss, Benkschr. Akad. Wiss. Wien, math.-nat. Cl. 
Band xxiii. 1864, p. 13, and Band xxviii 1868, p. 140. 
He also described a "variety" of the same species (pi. 
xix, fig. la). There are two other specimens in the collection 
of the University of Upsala labeled " Trochosmilia subcurvat a 
Reuss". The four specimens certainly represent three species 
belonging to two different genera
