150 Remarks on Fishes. 



sufficiently explicit. The species we have figured is pro- 

 bably his Chanda lala, which we may describe as follows: 

 — Embassis lala. Cuvier. 



The body (fig. 1, pi. IV.) is short, and much compressed, 

 translucent, with a silvery lustre and various iridescent lines 

 occasioned by reflected light on the sides. The operculum 

 (fig. 1 a. pi. V.) with a bifurcate point directed backward. The 

 orbitary bone (1. b.) with three points directed obliquely 

 downward, and the sub-operculum 1 . c. with four spinous pro - 

 cesses on its inferior margin. Three rays in the branchial 

 membrane (1. e.) mouth (fig. 2 pi. V.) directed obliquely up- 

 ward, with a single row of serrate teeth on the intermaxil- 

 laries. Fig. 1. a. PI. IV. represents the dorsal fins, 1. b. the 

 caudal, 1. c. the anal, 1. d. the pectoral, 1. e. the ventrals all 

 magnified. The fin rays are, 



D. 7.— 1/14 ; P. 9; V. 1/4; A 1/16 ; C. ; 20. 



The ventrals are situated opposite to the commencement 

 of the anterior dorsal, and behind the pectorals. The fin 

 rays are marked by minute cross bars, and the body with 

 microscopic star-like dots. The stomach and intestines 

 (fig. 1. PI. IV.) taken together are about the length of the 

 body, without cecal appendages. The stomach is dilated 

 irregularly at its anterior extremity a. a. fig. 1 f. ; b. the liver, 

 c. the gall vessel and duct. 



The scales 3. plate V. are perfectly translucent, and 

 exhibit five concentric rings or canals. 



Remarks on a new genus of Thoracic Percoid fishes. — 

 The second species we have to notice fig. 2, pi. IV. is re- 

 presented and described by Buchanan as an Atherina, as al- 

 ready stated, but the pectoral fins are round as in the Gobies, 

 and the ventrals are placed immediately below them, so as to 

 refer the species to the thoracic, rather than the abdomi- 

 nal Percoids, to which last Atherina belongs. The general 

 form of this species however renders its resemblance to 

 Atherina liable to deceive, particularly as its small size occa-
