MADEIRA AND THE CANARY ISLANDS. 
155 
First four pairs of swimming-feet (fig. 8) have strong muscular 
basal joints, from which proceed two 3-jointed branches with thick 
terminal setae. Fifth pair of feet each composed of a long 
joint, at the apex of which are three strong spinous setae. Abdo- 
men very muscular; the caudal setae are short, broad, and diver- 
gent, and are each terminated by three strong setae. 
One specimen only (a female) was taken in the tow-net at 
Orotava, Tenerifie. The lower part of the body is of a deep 
sepia colour. The animal is remarkably rigid and muscular. 
Quite recently a second form, evidently belonging to this new 
genus, has been found in the channel between Puffin Island and 
Anglesea. It is probably a male, and I am describing it under 
the name Cymbasoma Herdmani. It will be figured along with 
other new species from Liverpool Bay in the second volume of 
the ‘ Proceedings of the Liverpool Biological Society.’
