BRYOZOA FROM FRANZ-JOSEF LAND, 53 
most respects this resembles B. Murrayana, but in others it is 
like var. fruticosa. 
Sections of a specimen from off Cape Mary Harmsworth 
showed 21 tentacles, whereas a specimen of var. fruticosa from 
off West Point gave 17 tentacles; specimens from Greenland of 
B. Murrayana typica had 18-20 tentacles. In this and the 
variety there are two lateral rosette-plates, and one distal plate 
with numerous pores. 
In Bugula the rule is a row of small rosette-plates * near the 
distal border, and from the entirely different mode of connection 
it is possible that this species will be ultimately removed from 
Bugula. In Bugula it is not usual for the avicularia to be 
median. The Bugula hexacantha, Ortmann, from Japan would 
seem to be B. Murrayana. 
Loc. British seas, Scandinavia, Finland, Spitzbergen, Greenland, 
Barents Sea, Novaya Zemlya, Jan Mayen, Franklin Pierce Bay, 
lat. 79° 29' N. Japan? 
Jackson-Harmsworth HExp.: Cape Mary Harmsworth, 53-93 
fathoms. 
5. Bueuta MuRRAYANA, var. FRUTICOSA, Packard. 
In this variety the branches of the zoarium are usually 
narrower than in typical B. Murrayana, the marginal spines are 
absent, and the oral ones are often very slightly developed. 
There are no marginal avicularia, and the central ones are 
usually much less numerous than in typical B. Murrayana. 
A specimen from off West Point, Northbrook Island, has two 
oral spines on each side, avicularia placed centrally below the 
area of the zoccia, but no marginal avicularia. There are 
17 tentacles. 
Another specimen from the same place, also from 2-3 fathoms, 
consists of four or more rows of zowcia. The outer zoccia have 
one outer spine, while the inner zocecia have two pairs of oral 
spines. 
A specimen from off Cape Gertrude, 30 fathoms, has two 
small spines on the outer side of the zocecia, and one on the 
inner. There are no avicularia in this specimen.
