species of Eugorgia described by Verrill. Verrill's diagnosis 

 of the genus is as follows: — " Coenenchyma composed chiefly 

 of three forms of small spicula, which are naked at its surface. 

 There are two kinds of warty double spindles — longer and 

 usually sharper ones, and stouter and blunter ones. These 

 are intermingled with numerous double-wheels, which are 

 usually shorter; sometimes one of the wheels is shorter than 

 the other, or rudimentary, frequently there are four wheels 

 developed. The polyp-spicula are small, slender spindles. 

 The axis is horny. Branches either round or compressed, vari- 

 ously sub-divided, much as in Leptogorgia, surface finely 

 granulous. Cells mostly m a band along each side of the 

 branches, sometimes prominent, usually flat." 



Locality, etc. — Pieter Faure, No. 210. Cape St. Blaize, 

 S.W. by W., i W., 6} miles. Depth, 15-18 fathoms. By 

 dredge. Date of collection, July 15th, 1898. 



A large example of this species measuring 30 cm. in height 

 and ii-i2cm. in breadth. The specimen is not complete, and 

 shows that this species grows to a large size. The spicules 

 agree with those from the Cape St. Blaize specimens.

This species is represented in my collection by two speci- 

 mens from Algoa Bay. The axis is entirely homy, showing 

 concentric layers of fibre in transverse section. The specimens 

 are red or pink, with yellow polyps. The colony consists of 

 a main stem, flattened near the base, which gives off branches 

 on either side. In the larger specimen the primary branches 

 are fairly equal on each side of the main stem, but in the 

 smaller specimen they are much more developed on one side 

 than on the other. These primary branches may be simple or 

 undivided, but more usually they give off a series of second- 

 ary off-shoots, the latter in a few cases giving rise to others 

 of a third or fourth order. Polyos are situated on the main 

 stem, but for about half its length these are chiefly confined 

 to two sides, namely, those from which the branches arise, the 

 other two sides remaining more or less free from polyps. In 

 the upper part of the colony, however, the polyps are more 

 uniformly distributed on all sides, the bilateral arrangement 

 disapjjearing. The branches from the main stem do not, as 

 a rule, arise opposite one another. The apices of the branches 

 are frequently slightly pointed, several of the secondary 

 branches, however, have rather a stunted appearance, and ter- 

 minate in a lobe-like manner. In the lower part of the colony,
