 and truncate at the end. Verl•uc^B large and prominent, 

 ascending, the npper ones appressed, wholly obsolete on 

 the ends of the larger branches. Lateral cells crowded, 

 large and deep, with twelve to twenty-fonr distinct, but 

 narrow and nearly equal septa, which are a little exsert 

 and acute at summit. Coenenchyma between the cells not

 eight inches in diameter and height, consisting of vari-

 digitately lobed, or lacerately divided, at the ends. 

 Branchlets short, irregular, often like elongated verrucee. 

 On the larger branches the verrucse are small, irregular, 

 and distant. Cells rather large, rounded, not crowded ; 

 sometimes with twelve to twenty-four very narrow septa, 

 which are often abortive. Columella rudimentary or

 reticulated. The cells are small and in series ; borders

Note on Gorgonidoe. — Having recently had an opportunity to study 

 a large series of spicula, many of tliem prepared from authentic and 

 original specimens in vai'ious European Museums, and sent by Dr. 

 Kolliker, I have found it necessary to change the names of several 

 genera and species (see Amer. Journal Science, Nov., 1869, p. 419). 

 The names of species described in this Synopsis, which have been 

 changed, stand as follovps : — 



Eunicella venosa Verrill = Gorgonia venosa Val. 



E. palma Verrill = G. albicans KoU. 



Leptogorgia flammea Y .= Lopliogorgia palma E. and H. (non Pallas). 



Leptogorgia cuspiclata V. = Litigorgia cuspiidata V.
