Sir Edward Belcher brought an Uranoscope from China, which on a careful comparison 
with a Mediterranean specimen of scaber, presented no difference of form. Its colours were 
effaced. ;

This species is distinguished from the preceding, which it closely resembles, by having a 
tooth fewer on the under edge of the preoperculum and by other slight differences in form. 
I have had an opportunity of comparing Sir Edward Belcher’s Chinese specimen of scaber 
above mentioned with one of Biirger’s Japanese examples of asper belonging to the British 
Museum. The text of the ‘ Fauna Japonica’ quotes the rays of asper as D. 5|-11; A. 15, &. ; 
but a specimen in the museum of the Cambridge Philosophical Society, procured at Macao by the 
Rey. George Vachell, and Biirger’s one authenticated by Schlegel, present the formula which 
we have given above. ‘The last two rays of the dorsal and anal are approximated and may 
be reckoned as branches or separate rays, making the numbers 12 or 13 and 13 or 14, ac- 
cording to the way in which they are viewed.

A specimen collected by the Rev. George Vachell exists in the museum of the Cam- 
bridge Philosophical Institution, which ought, I think, to be referred to this species, though 
its fin-rays are as follows:—Rad. B. 6; D. 5|-20; A. 16; C. 138, &c. The caudal fin has 
the second long ray from the top lengthened as in pulchella; there are four rows of white 
spots on the anal; and the streaks on the head are nearly as exhibited in the ‘ Fauna Japonica,’ 
particularly a black crescentic mark behind each eye. The dots on the dorsal are mostly. 
effaced. 
I have some suspicion of the Japanese fish being merely a variety of the Percis nebulosa 
(C. et V. iii. p. 260), and that the Dentew fasciatus (Solander, Pisces Australie), or Percis 
emeryana (Richardson, Icones Piscium, t. 1. f. 1), is another variety; in which case the fish 
inhabits the ocean from Japan down to Australia.

It appears to me that the peculiar forms of the rays of the anal, as well as of some of the 
other fins, and many other particulars of structure, ally this group more closely to the T7i- 
glide than to the Percide. The Trachinus vipera has the suborbitar united by a bony bridge 
to the upper limb of the preoperculum, and other members of the group show more or less of 
that projection of the suborbitar chain which characterizes the following family.
