148 DESCRIPTION OF CORALS. 
close contact ; the angles frequently occupied by laminated cones, lamine ex- 
tending downwards within the terminal cup and often obliquely ; terminal cup 
deep, lined by the true lamella, upper margin slightly thickened ; additional 
stars interpolated.

The Astrea Stylophora of Goldfuss (Petrefacta, p. 71. t. 24. fig. 4, 1826— 
1833) is identified by two of the above authorities with Ast. emarciata, but in 
the ‘ Petrefacta,’ neither Lamarck nor De France is referred to; and the coral 
figured in that work apparently possesses even something more than a specific 
difference, eight rudimentary lamelle alternating regularly with eight very 
broad ; moreover not a vestige of a cone is given, or, supposing those projec- 
tions to have been removed by abrasion, of any plates on the sides of the ter- 
minal cups, which could be considered as downward extensions of the laminz 
of destroyed cones. In the text (p. 71) Meudon is given as the locality, but 
a competent authority doubts the accuracy of the assignment (Icon. Zoophyt. 
p. 158). Inthe absence, therefore, of full information, it has been deemed right 
not to include Ast. Stylophora as a positive synonym. ‘The reference in the 2nd 
edition of Lamarck (loc. cit.) to a Russian fossil described by M. Fischer de 
Waldheim in his ‘ Oryctographie de Moscou’ (p. 154), originated evidently in 
that author quoting the Ist edition of Lamarck ; but there is no agreement be- 
tween the Russian and French or English fossils, either zoologically or as _re- 
spects geological position. (See vol. i. App. A. p. 603 of Sir Roderick Murchison, 
M. de Verneuil and Count Keyserling’s work on Russia, 1845.) 
Since the notice on Styl. monticularia was written, M. Michelin has most libe- 
rally presented the compiler of these memoranda with a series of tertiary corals, 
carefully labelled; and he has thus been enabled to compare an authentic 
French specimen of Ast. (Styl.) emarciata with the one from Bracklesham Bay 
(obligingly lent by Mr. Edwards), and without detecting any marked differences. 
In all the leading essential structures, this fossil agrees perfectly with Styl. 
monticularia ; and it is hoped the remarks on the generic characters of that 
species, with their applicability to the coral under consideration, will be deemed 
sufficient to warrant the removal from Astrea to Stylophora*.
