Two parcels of Alcyonaria were sent to me in the year 1900. 

 With the exception of a dried specimen of Gorgonia albicans^ 

 all the specimens were, as before, carefully preserved and in 

 excellent condition for histological examination. 



I regret that a heavy pressure of work has prevented me from 

 completing my anatomical description of the species, but rather 

 than delay the statement as to the species occurring in Cape 

 waters, I have put together in this preliminary paper the notes 

 I have made upon the species. 



In these two consignments there are twelve species of 

 Alcyonaria and one of Stylasterina. Very striking pecu- 

 liarities in the structure of two Gorgonacea have necessitated 

 the foundation of two new genera — Malacogorgia and Tricho- 

 gorgia — and, in addition, four species of old-established genera 

 must be regarded as new to science, namely, Alcyonium pur- 

 pureum, Ceratoisis ramosa, Eugorgia gilchristi, and Juncell.^ 

 spiralis. Of the remaining seven species, three have not 

 hitherto been known to occur in Cape waters, and one, of which 

 a small specimen was incorrectly described in my last paper as 

 Primnoisis, is now referred to the species Wrightella coccinea, 

 which is also new to Cape waters. One specimen of a Gor- 

 gonia, probably belonging to a new species, is too incomplete 

 to describe adequately. 



The following is a complete list of the Alcyonaria which have 

 at present been found in Cape waters: —
