In the mode of branching, the size and structure of the branchlets, 

 and color, this closely resembles the last species, which I have 

 separated chiefly on account of the very different size and form of 

 the spicula, and especially ot" the double-wheels.* 

 Eugorgia rubens Vcrriii, sp. nov. 



Corallum slender, bipinnate and tripinnate. The small branches and 

 branchlets arise at distances of a quarter to half an inch apart, and are 

 either alternate or sub-opposite. Branchlets very slender, rather 

 short, the edges dentate by the prominent cells. Axis slender, seti- 

 form in the branches, pale amber-color, translucent. Cells prominent, 

 forming small conical verrucse, arranged in a single row along each 

 edge of the branchlets. Color pale red or rose-color. Diameter of 

 the branchlets ^08 inch ; of terminal branchlets ^06 ; length of branch- 

 lets ^35 to ^60 ; entire specimen 2 or 3 feet across. 



The spicula are pale red, and mostly short and stout. The longer 

 double-spindles are rather small, slender, not very acute, with about 

 three distant whorls of crowded warts on each end, the median ones 

 a little larger ; median space moderately wide. Stouter double-spin- 

 dles short and thick, blunt, with two or three close whorls of crowded 

 rough warts. Double-wheels rather large, with thick, round-edged 

 wheels, the outer ones terminal ; median space narrow.

C. — Dichotomous, terminal braiichleb- slender, elongated. Cells scarcely raised. 



Eugorgia Bradleyi Verrill, sp. nov. 



Corallum small, slender, more or less flabelliform. The round, 

 slender trunk arises from a flat, exj^anded base, and at the height of
