X. — A CONTRIBUTION TOWARDS OUR KNOWLEDGE OF THE 
POLYCHAETA OF SOUTH AFRICA. 
BY Dr. R. HORST. 
1. Amphinomidae and Aphroditidae. 
Professor Max Weber, during a short stay in South Africa in 1894, 
made a small collection of Annelids, which he kindly handed me over 
for examination. As I found among them some species, which for the 
first time are mentioned from this interesting region, where the fauna’s 
of the Atlantic and the Indo-Pacific meet each other, it will not be 
without interest to publish a short note about them. 
Euphrosyne capensis Kinb. ?). 
(— polybranchia Schm.) ?). 
At Seapoint, near low watermark, 8 specimens were collected, the 
largest of which has only a length of 16 mm., whereas its breadth 
measures 6 mm.; the number of the segments of this specimen amounts 
to 45. ; 
Eurythoë complanata (Pall). 
This species, already mentioned by Potts from the Seychelles *), was 
collected in a rather great number of individuals of different seize in 
the neighbourhood of Durban and Isipingo. The neuropodial bristles in 
the majority of the specimens have a yellow, smooth, bifurcated, distal 
part; in some specimens however the longer limb Move one or que 
shallow denticles. 
Chloeia fusca Me Int. 
It is the first time, that this pretty, little Amphinomid, widely distri- 
buted in the Malay Archipelago, as proved by the dredgings of the 
Siboga *), has been found on the coast of South Africa. Potts however 
had already stated its presence in the vicinity of the Amirante Islands, 
where it was collected by Mr. Stanley Gardiner in 1905. In these spe-
