The President in the Chair. 



Mr. Theodore Lyman read a paper upon a new genus 

 and species of Coral, Syndepas GouJdii. 



GENUS SYNDEPAS, (Lyiliail.) 

 Derivation, avv, deTrac, (goblet.) 



Growing in tufts (or single ?) ; calicles cylindrical or turbi- 

 nate ; striated on the outside with granulated ridges ; within 

 deep ; walls solid ; larger lamelliB exsert, finely toothed on their 

 edges ; budding from the side, low down, or from the coenen- 

 chyma between tlie calicles. 



This genus is distinguished from Desmophyllura of Ehrenberg 

 by the fact that the lamellae are toothed and not arranged in 

 bundles ; from Culicia of Dana, by depth of calicle, external 

 stria} and exsert lamelli^ ; from Cladocera of Ehrenberg by dif- 

 ferent mode of growth and by internal dissepiments ; and from 

 Dendrophyllia of Blainville, by different mode of growth and the 

 solidity of the walls. The Garyophyllia solitaria (Lesueur) and 

 the Caryophyllicp dUatata and j^ocillum of Dana will probably 

 come under the genus. 



SYNDEPAS GOULDii, (Lyman.) 



The general appearance is that of a cluster of little goblets 

 connected by a lime cement, which is often the resting-place of 

 Serpulfe, Bryozoa, and boring shells. The zoophyte buds, either 

 from the side, low down, or from the open space between the 

 calicles, {ccenenchyma, Edwards.) The group begins with three 

 or four cups, low, standing well apart, and connected at their 

 bases by a thin sheet of ccenenchyma. New buds appear, and 

 the whole growing upwards and outwards gradually makes a 

 tuft of crowded though independent individuals. The calicles, 

 though sometimes cylindrical, are normally turbinate ; within,
