The present specimens of Bugula Murrayana vary in shape and 
dimensions. Some of them are much divided into large spreading 
branches, others are more slender and elongated. The zooecia are 
long and frequently reetangular above; in habit they resemble more 
the zooecia of Bugula flabellata J. V. Thompson than the usual 
boat-shaped form of Bugula Murrayana. However the morpholo- 
gical character of the spines and avicularia, the distribution of the 
latter and the habit of the dorsal surface correspond elosely with 
the specific characters of Bugula Murrayana. The marginal spines 
are sparingly developed, usually 2—3 on the outer and inner edges 
of the zooecia. The aperture of the latter is very elongated and 
reaches to the bottom. Marginal avicularia much larger than the 
frontal ones; beak much bent. Radical fibres in great profusion. 
Not very abundant. Height from } to 1% inch. 
Loeality: Barents-Sea. 74° 0',5 N. lat., 37° 31’,5 E. long. 124 fathoms. 
Habitat. On shells, on Gemellaria.
