Corals from the China Sea , 
upright, at their summits with open, divergent, finger-like 
processes. The branches thin, with strongly incurved mar- 
gins, so that the outer or under surfaces are strongly convex, 
whilst their upper surfaces are deeply channelled, the mar- 
gins spinous ; the outer surfaces with well-marked costal 
stride, which are crested with very minute spines. Calices in 
single series at the bottom of the channelled upper surface of the 
branches, from 3 to 10 millim. apart. Calices depressed, less 
than 1 millim. wide; from 8 to 12 septa. Columella incon- 
spicuous, septa strongly and minutely spined laterally. The 
branches from 2*5 to 4 millim. in width. 
This species differs from the preceding in the narrower, 
more incurved branches, the smaller calices with fewer septa, 
and the more strongly marked costae of the under surface.

Incrusting, forming large masses with an uneven lobate and 
ridged surface, consisting of successive crusts about 4 millim. 
thick. The upper surface crowded with calices about *75 
millim. wide and 2 millim. from centre to centre. The calices 
with from 10 to 22 septa, large and small, the septa finely 
spined laterally, confluent as usually in this genus. The 
columella a blunted tubercle, sometimes compressed. 
This specimen, about 200 millim. in length, agrees in so 
many respects with Verrill’s description that it may fairly 
be referred to it. I do not, however, distinguish any of the 
dissepiments or u transverse septa ” referred to by Verrill.

Pavonia , sp. 
A fragment of a frond, thin, finely striate on the under 
surface, the upper surface alone with calices, irregularly 
situated between raised ridges running towards edge of frond. 
Same mode of growth as P. divaricata , but the calices 
restricted to one surface.

Pavonia , sp. n. 
Growing as small hollow stems partially incrusting round 
Annelid tubes, the under surface finely striate ; outer surface 
nodose and uneven, with numerous calices very irregular in
