14 G. LINDSTRÖM, ACTINOLOGY OF THE ATL. OCEAN. : 
l4. Oculina diffusa LAMK. 
Large and fine specimens from St. Thomas collected by Professor CLzLeEveE. He 
also brought home from the same island specimens of another Oculina, which in se- 
veral particulars resemble Oculina arbuscula AGaAssiz (VERRILL, List of Polyps and Co- 
rals sent by the Museum of Comp. Zool. Cambr. p. 46). 
15. Sclerohelia hirtella PALLaAs. 
Collected during the expedition of H. M. S. ”Eugenie” off St. Helena in 90 fathoms. 
16. Lophohelia exigua PourRTALES. 
Deep Sea Corals p. 26, pl. I, fig. 6 & 7. 
There are two detached calicles, dredged up by Dr Gois off Salt Island in 200— 
320 fms, coral gravel bottom. Costx prominent so as to give the coral almost a pris- 
matic shape. There are only three cycles in these specimens. 
17. Amphihelia ramea O. F. MUELLER p. p- 
A small fragment from 200—300 fathoms off Salt Island coincides as nearly as 
possible with one of the many varieties which are described by Duncan, viz. that 
figured by him on Plate 46 figs. 14—16 of his work on the Madreporaria of the Deep Sea. 
18. Amphihelia venusta M. Epow. & HaAiMe. 
From Barbadoes. As M. EDwaArRpDs gives ”Australie” as the habitat of this spe- 
cies, it may be somewhat doubtful whether it really is a Westindian species. But Prof. 
CHr. LovEN received a beautiful specimen of it by the apothecary residing on Barba- 
does, and he states that he does not doubt that it belongs to the surrounding sea. 
19. Axohelia Schrammi PoURrRTALES. 
Hassler Exp. p. 41, pl. VII fig. 2. 
Off Anguilla in 180—270 fathoms (Gois). The numerous specimens correspond 
with the figures and descriptions cited, only differing in having more shallow calicles. 
20.  Cryptohelia virginis n. 
P1. Il; fior 24. 
Oft Salt Island in 200—320 fms (Gois). I refer to this genus some small spe- 
cimens of an apparently new coral. The coenenchyma is longitudinaly and faintly 
striated, the calicles all fading the same way, leaving the other side quite smooth. 
They are transverse, curved, almost erescentshaped and more narrow at one end than
