Rather numerous specimens of an Amphihelia, agreeing with Seguenza’s spe- 
cies better than with any of the varieties of Amphihelia ramea figured by Pro- 
fessor Duncan, were dredged in this locality. 
Amphihelia rostrata Pounr. spec. nov. 
Plate I. Figs. 4, 5. 
Corallum flabellate, with all the calicles facing one way ; coonenchyma dense, 
finely striated in all parts, the striæ finely spinose and formed by the continua- 
tion of the costa. The calicles at first rather long infundibuliform, the young 
rising singly or in pairs from the border of the older ones. On the older 
branches the calicles are irregularly alternate and but little prominent. "Three 
cycles of septa, in six systems, with entire edges. Primaries and secondaries 
equal and reaching the loosely spongy columella ; tertiaries smaller. One of the 
primary septa, generally on the side opposite to the branch, is very much thick- 
ened, and projects with its costal part outside the calicle in the shape of a rounded 
spur about 2 mm. long. This appendage is entirely disconnected from the 
budding process, which always takes place on the opposite side, or nearly so, 
This elegant coral must have had a spread, when entire, of about 12 cm. 
Diameter of thickest branches, 5 or 6 mm.; of calicles, 3 to 4 mm. The polyps 
seem to have been of a pinkish color when alive. The coenenchyma is pure 
white.
