included some other genera as for instance Stenella and Primnoölla. I have not been able 
to ascertain the presence of such interior spicula in the body of the polyps of Calyptro- 
phora, as are so easily found in Primnoa. <Calyptrophora differs moreover from 
that genus in the more developed scaly covering of the axis, which is almost entirely 
wanting amongst the closely crowded polyps of Primnoa. The calicle of Calyptrophora 
consists only of three pair of scales, in Primnoa there are several rows of imbri- 
cated scales. 
2.  Caryophyllia clavus ScaAccHi var. borealis. 
Duncan, Madrep. Deep. Sea p. 312, pl. 48, fig. 6. 
A single specimen dredged up during the expedition of the ”Josephine” in 109 
fathoms at; Lat. 48”; 19 N; Long: 85,45, W. 
3. Caryophyllia Berteriana Epw. H. 
There are two small specimens, the largest having only 10 paluli, but else cor- 
responding with the descriptions and figures of MILnNE EDWARDS and PourTtTALEs. Off 
the Virgin-Islands (Salt-Island) in 200—326 fathoms amongst fragments of corals 
(Gois).

? Paracyathus thulensis, Gosse Actinol. Brit. p. 319. 
From the N.W. Atlantic in Lat. 53” 34 N.; Longit. 52” 1' W. in 980 fathoms. 
Dredged up by Dr J. LINDAHL during the expedition of H. M. S. ”Ingegerd” to Green- 
land in 1871. Also a specimen off the Azores, Punta Delgada in 100 fathoms (Exp. 
of the ”Josephine”). 
This coral cannot properly be classed with the genus Caryophyllia as there are 
no regular paluli and all such are entirely wanting in the North-Atlantic specimen. 
But my material is too scanty to decide the question. 
As may be seen by the accompanying figure, carefully drawn by M. WESTERGREN, 
the systems are very unequally developed, one for instance having no less than five 
cycles and the others only three. The North-Atlantic specimen has a columella which 
consists of a single plate, much bent and twisted and sending forth curved and wavy 
lamellar processes. 
Length of the North-Atlantic specimen 6 mill., breadth also nearly 6 millim. 
The Azorean specimen is somewhat smaller. It is possible that this species already in 
1860 was described by Gossr in Actinologia Britanica p. 319 as Paracyathus thulensis, 
with which it agrees in several important points.
