On Corals from the Ch ina Sea . 
Eyes almost in contact, the upper slightly in advance of the 
lower, which is on the lip ; their major diameter is more than 
one sixth the head-length. On the coloured side only one 
nostril, in the form of a rather long slender tube situated in 
front of the lower eye ; on the blind side two, the anterior of 
which is a short tube. 
Mouth small, its angle nearer to the tip of the snout than 
to the gill-opening. Scales ctenoid on both sides. Two 
lateral lines on the coloured side, which branch and anasto- 
mose on the head ; the upper, which ends immediately behind 
the vertical through the middle of the body, is separated from 
the lower, which is continuous to the base of the caudal, by 
ten rows of scales. No lateral line on the blind side. One 
ventral fin united to the anal by a broad membrane. The 
highest [middle] dorsal and anal rays considerably exceed 
the length of the snout. 
Colours in life : — Left side uniform sepia-brown. 
Length nearly 5 inches. Two specimens. 
Off Ganjam coast, 33 fathoms ; bottom sand. 
These two species are closely allied, both belonging to the 
subgenus Trulla ) Kaup.

A large, massive, incrusting specimen about 22 centim. in 
diameter, the upper surface uneven, with blunt rounded 
ridges, thickly covered with subpolygonal or compressed 
calices, from 3 to 6 millim. in width. Walls thin, but only 
visible here and there; they are apparently thick at the sur- 
face. The septa from 22 to 30 in number, very thin, plate- 
like, their sides minutely spined, the margins subentire or 
very minutely serrate, their upper edges above the calice-walls 
sometimes confluent with adjoining septa. Apparently no 
columella, but numerous dissepiments. Calices deep ; the 
larger septa reaching nearly to the centre.
