TRIBE I. ASTR^EACEA. 289 



of Freiburg ;* and to him am I indebted for a knowledge of Esch- 

 scholtz's genus, which had been overlooked by Ehrenberg. 



The Ecmesus of Philippi, placed by him near the Fungise, appears 

 to be a flat Turbinolia, and belongs rather to the tribe Caryophyllacea, 

 than to the Astrseacea. The PhylJodes of this author includes cuneate 

 species, and has the same relations.

F.pumila, orUcularis aut subelliptica, ore oblongo; supra convexum et 

 infra concavum. Corattum subtus tenuissime radiatum; supra lamel- 

 lis incequalibus, crenulatis, latere asperis. 



Small, orbicular, or subelliptical, mouth oblong; convex above and 

 concave below. Corallum below very finely radiate ; above, with 

 the lamellae unequal, crenulate, lateral surface rough. 



Austral Seas. Peron and Lesueur. Lamarck. 



Lamarck states that this is a neat species, very convex above and 

 slightly concave below, resembling, in general aspect, the agarici-
