transversely disposed spicules. Over the whole surface of the polyp there is a dense covering 
of transverse spindles, which are covered with small roughnesses. Most of the spindles are 
slightly bent, some arcuate. 
We have not material on which to base a judgment as to the position of either Cereopsis 
or Daniela, but we think that the two genera should be kept together. 
Previously recorded from the Gulf of Naples. 
Genus Sinularia (= Sclerophytum). 
Luttschwager has shown in his Revision (Beitrage zu einer Revision tier Familie Alcyo- 
niidae, 1915) that the rules of nomenclature demand that May’s name Sinularia (1898) should 
replace Pratt’s more familiar name Sclerophytum (1903); and with this we must regretfully 
acquiesce. We follow the order of Luttschwager’s revision : — S. leptoclados , 5 . polydactyla , 
S', herdmani , S', querciformis , S. dura , S. rigida , S. whiteleggei , S. gardineri , S. capitalis. 
Then follows: S. fiexibilis , which we originally regarded as new, S. tentaculata.

Numerous specimens, including luxuriant and massive colonies, from various stations, 
show the features of this species. All have a characteristic spiculation, and a branching type 
of growth, though a considerable amount of variation is found in the size and appearance of 
the branches, which include the thick blunt type figured by Burchardt, more slender elongated 
forms, and others with the twigs reduced to very small blunt outgrowths. The surface is like 
stiff leather throughout, but the branches break off very readily. 
The spiculation is characteristic and includes: 
(1) massive internal spindles with compound warts. These may attain a length of 4 mm. They 
are both straight and curved. There is an occasional bifurcation at one end. Breadth = 
o 
0.45 mm.; 
(2) slightly narrower large spindles from the interior, with simple conical prominences; 2.5 X 
0.24 mm.;
