Sir Edward Belcher brought an Uranoscope from China, which on a careful comparison 

 with a Mediterranean specimen of scaler, presented no difference of form. lis 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 preopcrculum and by other slight differences in form. 

 I have had an opportunity of comparing Sir Edward Belcher's Chinese specimen of scaler 

 above mentioned with one of Burger'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, &c. ; 

 but a specimen in the museum of the Cambridge Philosophical Society, procured at Macao by the 

 Rev. George Vachell, and Burger'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. 1G; C. 13§, &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 nelulosa 

 (C. et V. iii. p. 2G0), and that the Dcniex fasciatus (Solander, Pisces Australiae), 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 Tri- 

 glidce than to the Percidce. The Trachinas vipera has the suborbital- united by a bony bridge 

 to the upper limb of the preoperculuni, and other members of the group show more or less of 

 that projection of the suborbital- chain which characterizes the following family.
