Corals from the China Sea . 
Only a single specimen was obtained, which is about 50 
millim. in width at the summit and *45 millim. in thickness ; 
but the mass below the summit-platform of coenenchyma is 
apparently dead and extensively eaten into by sponges.

Symphyllia labyrinthica ) sp. n. 
Corallum large, massive, rudely inverted, conical, with 
plane or slightly convex surface. Lateral and under surface 
with longitudinal strise, apparently not spinous, this surface 
usually covered by attached organisms quite close to the upper 
margin. Upper surface of sinuous labyrinthine calicinal 
series, the walls completely amalgamated, with no traces of 
grooves between. Width of calices 13 to 15 millim., depth 
8 millim. There are usually two septa connecting the cali- 
cinal centres, sometimes traces of a third, sometimes only one 
is present. There are about fourteen large and small septa 
in the distance of 10 millim., the large septa with prominent 
spinous teeth, the smaller serrate or unequally jagged. 
There is but a single specimen, which is 7*5 centim. in 
height and 25 centim. across the surface. 
This species is nearest allied to S. agaricia } E. & H., and 
to S. acuta , Quelch, but from these it is readily distinguished 
by the narrowness and less depth of the calicinal valleys. 
It has been compared with S. neglecta , a MS. species in the 
British Museum, but its mode of growth and other features 
readily distinguish it from the type of this form.
