West Indies. 



This large species is distinguished by the length and size of the 

 calicles or calicular branches, and the serrate lamellae that crowdedly 

 striate the exterior for several inches from the summit. In Peale's 

 Museum at Philadelphia, there is a single turbinate branch or calicle, 

 which is four inches long and three broad at top, with a slightly ellip- 

 tical outline.

young individual (?), a short cylindrical 

 calicle, two and a half inches in diameter, 

 and two-thirds of an inch high, and very 

 similar to the extremity of a calicle in 

 Ellis's figure.

Several of Seba's figures on tab. 108, 109, 

 and 110 (Thes. iii.), are generally re- 

 ferred to as young of this species ; but 

 the correctness of these references may 



be doubted. No. 2 and 4, tab. 108, re- 

 presenting specimens from "New Spain," 

 look like attached Fungis: the first is two 

 and a half inches in diameter, the second 

 three and a half; and the pedicel in each 

 is very short, and about one-third the 

 diameter. 



Seba's No. 2 and 3, tab. 109, appear to 

 be figures of a branching species with 

 shallow calicles one and two-third inches 

 broad, and the height scarcely half their 

 breadth. A specimen of this kind was 

 obtained by the author in the Sooloo Sea, 

 the calicle of which was one and a half 

 inches wide, with the cell spreading and 

 nearly one-third as deep, the lamellse 

 very unequal and remote, and the mar- 

 gin of the cell uneven from the unequal 

 and unequally prolonged lamellae. As 

 the specimen is an imperfect one, it is 

 not here named.
