Several examples of a Chinese fish strongly resembling the preceding exist in the Chinese 
collection at Hyde Park and in the British Museum, but differing from it in having a preoper- 
cular notch and subopercular knob, both slighter than is usual in Diacope. Neither the spe- 
cimens nor drawing agree sufficiently with Russell’s figure 110 (Mesoprion quinquelineatus, 
C. et V.), nor 98 (Diacope notata, C. et V.), nor with Bloch’s M. johnii (318), to be referred 
to either of them. 
The canine teeth in the upper jaw are acute and well-apart. In the lower jaw there is a 
short one in the middle of the limb on each side. The vomerine and palatine teeth are covered 
by the horizontal velum. The preorbitar and lower jaw are studded with minute pores. A 
small pit exists on the chin. The scales of the cheek form an oval oblique band extending 
from the temples to near the corner of the mouth, bounded above by smooth integument, 
which spreads over the preorbitar and below by the disc of the preoperculum. Preoperculum 
having a broad disc coarsely toothed at the corner, some of the inferior teeth pointing forward ; 
under limb serrated ; operculum with two obtuse lobes. The darker discs of the scales form 
rows of faint spots. Second and third anal spines about equal in length, the second one a little 
the stoutest, and neither of them equal to the soft rays in length.
