MUSEUM OF COMPARATIVE ZOOLOGY, 211 
The rows of calicles are very irregular, generally forming a broad, flat furrow, 
with the pores for the tentacular zooids rather removed and in the form of 
small transverse slits on the side of a ridge, as in D. cervina. The branches 
grow out from one edge of the furrow, causing the latter to widen out and the 
other edge to extend across the new-formed branch. Sometimes the rows of 
calicles become double. The only specimen obtained has very few and indis- 
tinct gonophores. Color whitish ; height 45 mm. 
This species differs, by its peculiar mode of branching, from all the other rep- 
resentatives of the genus in our collections.

Nors., The Favosites mentioned in Mr. Agassiz's letter No 1. (Bull. Mus. Comp. 
7۵01: Vol. V. No. 1) proves, on examination of its internal structure, to be quite differ- 
ent. Being dry, the soft parts could not be examined satisfactorily. Mr. Moseley, who 
has examined a portion of it, expresses a strong suspicion that it is a Bryozoon, per- 
haps related to some mushroom-shaped Bryozoa in the ** Challenger" collection. A 
description will be deferred until after next season's dredgings, in the hope of obtain- 
ug some alcoholic specimens,
