DENDROPHYLLIA. 45 



DENDROPHYLLTA Blainv. 



Dendrophyllia cornucopia Pouut. 



Plate v., figs. 7 and 8. 



Corallum elongated, conical, generally curved, budding irregularly 

 at various heights and on all sides. The younger corallites, remaining 

 much smaller than the parent stock, implanted at right angles, after- 

 wards curved upwards, but irregularly. Costoe distinct, but not promi- 

 nent, finely porous. Sometimes a very rudimentary epitheca. Calicle 

 elliptical, fi)ssa rather deep. Septa thin, finely granulated, serrated in- 

 side of calicle, entire above, in six systems and four c^^cles in all the sys- 

 tems, the fifth in some of the quarter-systems adjoining the primaries. 

 Columella large, densely spongy, elongated, and slightly convex. 



Height of largest specimen 10 cm. Greater diameter of calicle 18 

 mm., lesser 16 mm. The younger ones budding out are not more than 

 6 mm. in diameter in any of the specimens. 



A specimen has thirty-two buds, the largest has eighteen, smaller 

 ones have none. 



The polj^p is of a deep maroon color, darkest on the disk, lighter on 

 the wall. 



Off Key West, in 120 and 125 fathoms. 



A specimen of Dendrophyllia, rather incomplete, in the collection of 

 Mr. R. Arango, in Havana, appears to be D. cornigera of which the 

 Museum of Comparative Zoology possesses numerous specimens from 

 Fayal. It differs from our species by the large size of the buds, Avhicli 

 rapidly equal the parent stock. They are also usually confined to two 

 sides of the main stock. 



Dendrophyllia cyathoides Pouut. 



Plate I., figs. 8 and 9. 



Corallum broadly attached, elongated, branching irregularly and 

 apparently only a few times, generally widened at the calicle. CostoB 

 distinct to the base, in j)f^i't veiled by a rudimentary epitheca, but 

 prominent and serrate near the calicle, and continuous with the septa, 

 which are thin, granulate, rounded, finely serrate, more exsert than in 

 any other species of the genus, in six systems and four cycles, mostly
