This specimen, which measures 26 inches, is remarkable for 
its great length, and its branching differs in some respects from the 
normal form. MHincks states that the ramification of A. myrio- 
phyllum is very slight and simple, seldom passing beyond a single 
division of the shoot which generally takes place not far from the 
base. In this case the first branch is far from the base, and it 
divides again into two long branches. 
Although the species is rare, it is occasionally met with in the 
Firth of Clyde, and particularly off Fairland Point, Cumbrae, 
where it occurs On muddy-stony ground at a depth of from 20 to 
23 fathoms. The specimens from the Clyde sea-area that have 
come under my notice frequently exceed 12 inches in length. 
According to Dr. Johnson, in his British Hydrozoa, the 18-inch 
specimens referred to above were taken by Landsborough at 
Lamlash. 
The Cirripede Scalpellum vulgare, attached to a shoot on the 
right-hand side of the specimen above referred to, is frequently 
met with on the stems of Antennularia ramosa.
