Cycloseris sinensis, M.-Edwards et Haime, Hist. nat. des Corall. iii. p. 51; Gardiner, Fauna and 
Geogr. Maldives & Laccadives, p. 944, pl. 91. figs. 14-16. 
A single specimen, 74 mm. long by 67 mm. broad by 19 mm. high, and with about 
410 septa, belongs to this species. It is larger, but otherwise agrees closely with the 
Maldivan specimen. Costs are present corresponding to all cycles of septa except the 
last ; they are subequal in size. 
Locality. Cargados Carajos, 30 fms. Also known from the Maldives (27-30 fms.) 
and China Sea (IZ-Ed. § #.). 
4, Fungia somervillet, sp.n. (Plate 34. figs. 5, 6.) 
A single oval-shaped specimen differs so markedly from all previously-recorded 
forms that I have no hesitation in describing it as the type of a new species, which I 
have named after Comm. Boyle T. Somerville, H.M.S. Sealark. 
Corallum oval in shape. aboral surface flat, slightly hollowed in the centre, oral 
surface much arched for about 18 mm. round the elongated axial fossa, rest flat, whole 
comparatively thin. Coste corresponding in number to the septa, very fine and low, 
extending into wavy lines over the original scar of attachment, about every fourth 
slightly thicker and more prominent, sides almost smooth, minute teeth on their edges. 
Axial fossa elongated, about five times as long as broad, closed in below by a columella 
of small, rounded papille. Septa of eight cycles, last incomplete, I-III subequal, 
much thickened, ending almost perpendicularly at the sides of the axial fossa against 
the columella, rest gradually decreasing in size. Septa of cycle VII fused to those of 
cycle VI, and of cycle VIII to those of cycle VII, but the free edges of the septa of 
eycles VI and VII after such fusion continuing towards the columella at the level of the 
edges of the lower septa. Sides of septa very finely grained, running into lines perpen- 
dicular to the edges of the septa, where they end in minute angular teeth. 
The single specimen is 114 mm. long by 90 mm. broad, about 6 mm. thick at its 
edge by 20 mm. in the centre, axial fossa about 18 mm. long, top of columella about 
11 mm. below highest septal edges ; about 660 septa. 
Locality. Seychelles, F 5, 44. fms. A second specimen in a dead and rather broken 
‘condition was dredged in the Amirante Group, E, 20 fms. ; it measures about 125 mm. 
long by 98 mm. broad. 
The specimen has the primary septum at one end of its axial fossa rather broken and 
fused up with neighbouring septa, otherwise it is very regular. Its nearest ally perhaps 
is F. sinensis, but it is by no means an elongated form of that species.
