TRIBE II. CARYOPHYLLACEA. 373 



This small species occurs in curved turbinate forms, (and probably 

 also erect,) seven lines high, four and a half by three and a half in 

 breadth at top, and one line at base ; it is finely striate to the base, 

 with the exterior surface a little undulate. The larger lamellae are 

 hardly half a line exsert. The bottom is linear, and consists of ragged 

 points. Young state of the cyathus? 



The Cyathina cyathus of Leuckart (De Zooph. Coral, figs. 5-7, pi. 4), resembles this 

 species. It is from the Mediterranean, is three-fourths of an inch high, seven by five 

 lines in breadth above, and one and three-fourths lines at bottom ; it is coronate, with six- 

 teen thin papillae, each papilla belonging to the middle lamella of the three intermediate. 

 The striae of the exterior are finely denticulate. Leuckart adds " An species diversae ?" 



Philippi suggests that the Monomyces eburneus of Ehrenberg may be the young of 

 the C. cyathus. (Wiegm. Arch., viii. 44.)

GENUS III. STEPHANOPHYLLIA. MICHELIN. 



Cyathophyllidce non gemmatce, liberce, disciformes, subtus planiusculce. 

 Corolla superne lamettis prominentibus radiata. 



Non-budding Cyathophyllidae, free and disciform; below, nearly flat. 

 Coralla above, radiated with prominent lamellae. 



The lamellae in the species which is the type of Michelin's genus 

 stand quite prominent around the centre, and are somewhat dentate. 

 The appearance is much like that of a Fungia. The name alludes 

 to the crown-like corallum, and is from <r<re<?avov, a crown. Some of 

 the species referred here by Michelin, appear to belong to the Ec- 

 mesus of Philippi.
