POUETALES, Deep Sea, Corals p.sl2,:pllhufopke2, 3. 
Off Villa Franca in the Azores in 200—600 fms, on the Josephine bank in 228 
fims, in the Atlantic Ocean Lat. 36” 4835 N., Long. 14? 125 W. in 162 fms. (Exp. of 
the ”Josephine”). A specimen from the last locality has 5 mm. in breadth, 3 mm. in 
height. 
This is quite the same species as the Westindian, though my specimens do not 
show the same irregularities in growth on the inferior surface as those sent me 
for inspection by Count PourtaLEs. Still it is subject to much variation. Generally 
it is spherical, but it also assumes a conical shape, elongated, 5 millim. in height and 
4 millim. in breadth. There is then often a peculiar growth downwards of the rims of the 
calicle along the exterior sides of the corallum, and the septa continue downwards, as 
shown in the figure. In others again there has been an interruption of the regular 
growth and the animal has contracted its cirecumference within more narrow limits and 
there formed a new calicle (see fig. 7). There are no paluli, and the papille which 
compose the columella, may sometimes be mistaken for paluli. The septa are in five 
cycles of six systems. 
This species, as well as the following, can not be elassed with the Leptocyathi 
in the sense of MIEnE EDWARDS and HAIME, but inggead of causing more confusion by 
creating a new, perhaps unnecessary genus, I for the time rank them with Leptocyathus. 
6. Leptocyathus? halianthus n. 
PERS: 
Dredged up during the expedition of H. M. S. ”Eugenie” (in 1852) off Cap Frio (41” 
41: W., 22? 47 S.) in 30 fathoms.  Breadth 11 mm. height 5 mm. 
It is largely affixed with a broad basis on Pectens and fragments of other bivalve 
shells. It is simple. The wall is either naked or partially provided with a thin epi- 
theca towards the basis. The animal covers the whole coral to its basis and there 
accumulates around itself grains of sand and fragments of shells. The coste are covered 
by some sparse or rare warts or spines, which on old, eroded specimens when broken off 
leave a small pit on their site, thereby indicating that they are interiorly hollow. Septa in 
six systéms of five orders, all systems alike. Those of the third order unite at their base 
with the septa of the second order and, again, those of the 4'h and 5'" orders are united 
with those of the third. They are all moderately exsert, covered with regular, oblique 
rows of granulations on the lateral surfaces, their superior edge is also finely dentate 
or granulated. The columella is formed by about 30 small, slender papille, styliform, 
angular, eneroaching on the basis of the septa, and there forming, as it were, a sem- 
blance of paluli. This species is only provisionally to be ranged in the genus Leptocyathus as
