at the other. The inferior lip is very slightly turned up. There is a columella and 
the septa are very short, about fourteen. The width of the calicles is 2 millimeters. 
21. Stylaster roseus PaALLaAs”). 
A small specimen dredged up by Dr Goös off Anguilla in 100—150 fathoms. 
The coenenchyma is smooth with pores and tubes which traverse it. 
To the division of the Stylasteride belongs also a small coral, which is figured 
in P1. II, fig. 25. It was collected during the expedition of the ”Josephine” on the Jose- 
phine Bank (340 fms). It is 4 millim. in length and has 12 short, thick septa and no 
columella. The epitheca or coenenchyma is vermicular or scrobiculate of a pale brown- 
ish colour. There is a smaller calicle on the lower side. 
22. Madracis decactis LYMaANn. 
FÖRETALKS, Deep Sea Corals p. 28, pl. VII, fig. 1—3. 
Off Virgin Islands (Salt Island) in 200—320 fathoms, Gobs. It occurs as well 
with deep calicles as with shallow ones. 
23. Schizocyathus fissilis POoURTALES. 
P1. II & III, fig. 26—34. 
Hassler Exp. p. 36, pl. 6, figs 12—13. 
Dr Goös has collected this extremely curious coral off St. Martin in 200—300 
fms, off Anguilla in 200—380 fms, and off Salt Island in 200—320 fms. The natura- 
lists of H. M. S. ”Josephine” brought it home from the Atlantic Ocean, 38” 103' N., 
Y9E25 Win 790 fathoms and from 38” 7 N., 9718 W. in 550 fathoms. 
Largest specimen 35 millim. in length and 3 millim. in breadth. The segment 
of a cloven specimen attains 7 millim. in length. 
The coral is regularly cylindrical, only slightly increasing in width towards the 
calicle, the smaller specimens are more cupshaped. The epitheca of the Westindian 
specimens is glossy, very finely striated by minute, transverse lines, which are crossed 
by equally fine, longitudinal strie. In the Atlantic specimens the epitheca is more 
coarse and thick, and much more transversally rugose. The exterior margin of the septa 
is visible from without through the thin epithecal covering and this gives a semblance 
to coste. Moreover there are longitudinal, very regular rows of dots of a pale colour 
or instead of them small holes, which pierce the epitheca. They begin somewhat 
below the rim of the caliele. They are placed between the primary and the secon- 
dary septa, between the secondary and tertiary septa there are none. The wall proper 
between the septa consists entirely of the same sort of thin epitheca, which surrounds 
the whole outside of the coral or in other words, there exists no wall as a separate forma- 
tion, distinct from the epitheca. In adult specimens the septa are of three orders in 
six systems. There are six of the first order, twelve of the second and six of the 
!) When this paper was presented to the Academy, I was not aware of the researches of SARs and MOSELEY 
as to the nature of the animals of the genera Allopora and Stylaster, in consequence of which these and 
the allied (N5 15—21) ought rather to be referred to the Hydrozoa.
