Specimens from China have been presented to the British Museum by John Reeves, Esq., 

 and to Haslar Museum by Sir Edward Belcher and Capt. Dawkins, R.N. 

 The teeth are entire, chisel-shaped and trenchant in a single row.

Glyphisodon tyrwhitti, Benn. Ceylon {Chcetodon), pi. 25 ; Icon. Reeves,

A specimen of this fish in the British Museum, brought from China by Mr. Reeves, can be 

 distinguished from the preceding only by the teeth, which are those of a Dascyllus, and are 

 villiform, with the front row stronger. It has not the aspect of a Dascyllus, nor the serrated 

 preoperculum. It is not easy to say which of Mr. Reeves's drawings, a. 31 or 256, repre- 

 sents this fish best, but on the whole we have thought proper to refer to the former, which 

 indicates the blue borders of the caudal more distinctly. The two figures are illuminated 

 much alike, viz. with fine vertical blue or black bands, and intermediate spaces on the back 

 of bright gamboge yellow. In a. 31 the yellow colour spreads over the dorsal to near its 

 edge, while in 256 the fin is uniformly dark blue, the scaly sheath at its base being yellow; 

 a. 31 has also a crimson-red head and a streak of carmine round the base of the pectoral. 

 Length of figure 6 inches. 



Hab. Canton. Ceylon. 



Glyphisodon rahti, Russell (Bahti-pola), 86 ? C. et V. v. p. 456 et ix. 

 p. 507? Icon. Reeves, a. 33; Hardw. 142. 



The prevailing colour in Mr. Reeves's drawing is pale mountain-green, without any of the 

 yellow of the preceding two species. The cheeks and gill-covers are crimson. The fins are 

 greenish, but darken greatly towards their borders. The species has been determined solely 

 from the drawing, and is doubtful. In the ' Histoire des Poissons,' Bennet's figure of Chce- 

 todon tyrwhitti is referred to rahti, but as it is illuminated in accordance with Reeves's figure 

 a. 31, I have considered it to be a representation of the specimen described in the preceding 

 article. 



Hab. Red sea. Indian ocean. Malay archipelago and Chinese sea.

Examples of this species, procured in the China seas by Capt. Dawkins, R.N., were pre- 

 sented by him to the museum at Haslar.

We have not seen a specimen to which we could refer Mr. Reeves's drawing 274 (Hardw. 

 145), and are unable to determine the genus to which it belongs. It has the aspect of Gly- 

 phisodon, a large eye, narrow preorbitar, oblong-oval form, the height of the body being equal 

 to half the distance between the snout and the base of the caudal fin. The rays are D. 13(11 

 or 12 ; A. 2|10, &c; the second anal spine is stouter than usual, the caudal much forked with 

 pointed lobes, and there is a filiform tip to the ventrals. The general tint is dark greenish- 

 blue without bars, the head glossed with crimson, the fins blackish-brown, and a black mark 

 on the base of the pectoral. The drawing, like the rest, was executed at Canton. It measures 

 5 inches. 



Glyphisodon bankieri, Richardson. Bad. D. 13|11; A. 2|11 ; C. 15 ;

The only example we have seen of this species was sent to Haslar Museum from Hong 

 Kong, by Surgeon R. A. Bankier, R.N. It has the oblong form of a Pomacentrus, the height 

 of the body being contained thrice and a half in the total length, caudal included. The teeth 

 stand in a single row and are chisel-shaped, with truncated entire tips. The eye is large ; 

 the preorbitar and suborbital' chain very narrow and not toothed ; the vertical limb of the
