LEPIDOPORA. 39 



pullae, each of which has a small lateral opening. They are less 

 numerous on the other surface. Columella deep seated, long, hirsute, 

 in the shape of a pointed club. Color orange-pink. Height 4 to 5 cm., 

 thickness 2 to 3 mm. 



This species differs from the preceding by its smaller calicles, not 

 placed in a furrow, irregular lateral pores, and serrated edge.*

Plate VI., fig. 5. 



Corallum branching, very slender. Calicles confined to one side of 

 branches, round, without lip or trace of septa. Perforated tubercles 

 prominent, continued downward in sharp ridges. Columella slender, 

 elongated, hirsute, too deeply seated to be seen without a section. 



Having but a very small specimen of this coral, the determination 

 of it remained uncertain until a part was sacrificed for a section, when a 

 view of the columella settled the question. 



The branchlets are only a millimeter and less in diameter. 



Off Havana, in 270 fathoms. 



* There is in the Museum of Comparative Zoology a specimen of a third species of Distichopora 

 of West Indian origin. It was received from St. Thomas, through Mr. Duchassaing, and appears to 

 be undescribed. It has nearly cylindrical branches, fl ittened more or less near the ends. Calicles 

 in a very flat furrow, rather crowded. Lateral pores more developed in one of the series than in 

 the other, transversely elongated, on top, or down the side of small tubercles, thus forming an 

 approach to the structure of Errina. Smaller branches studded with ampulla;, scatteied om s on 

 the main stem. Color white. I would propose for it the name of Distichopora cercina.
