164 ZOOPHYTES. 



Convex, furcato-ramose ; disks mostly simple. Corallum having the 

 calicles subturbinate, scarcely 2 lines distant, the exterior minutely 

 striate; cell usually an inch broad, sometimes 1 inch long ; lamellae 

 very broad, extremely thin, a very little exsert.

The small size of this species readily distinguishes it. The lamellae 

 meet or overlap at the middle of the cell, and are very fragile. The 

 exterior is finely striate, but not spinulous or properly denticulate.

Furcato-ramose, hemispherical ; disks usually simple and nearly cir- 

 cular. Corallum with the branches subdivaricate, ^ to | of an inch 

 thick, calicles subturbinate ; coarsely ribbed-striate and spinulous, 

 below nearly smooth; lamella? unequal, very broad, exsert, ob-

 smaller intermediate.

This species is remarkable for the strongly ribbed spinulous exte- 

 rior of the calicles (allying it to the Mussae), and the decided line of 

 division between this live portion, and the smoother dead part below. 

 The lamellae are broad with the inner margin vertical ; and the oppo-
