below, but no palatal band discernible in the specimen : body subcylin- 

 drical, compressed, becoming more so to the tail. 



Amb. cjecutiens, nobis, n. s. Head broader than the body, flat, obtuse 

 at the muzzle ; the mouth moderate, its cleft scarcely continued back 

 laterally : cirri large ; the upper labial cirrus reaching to tip of pec- 

 toral fin, and the exterior lower one nearly as long. Body long and 

 CoBiTis-like. The number of fin-rays is difficult to determine, but seems 

 to be

Colour dark brown above, paler beneath. Length of specimen 3 in. 

 To describe this little mud-fish properly, a series of specimens are 

 required, or the sacrifice* of our only individual. It will, however, be 

 readily identifiable from the above notice. The individual described was 

 procured by Mr. W. Theobald, Junr., at Maulmein ; and others, but 

 in much injured condition, have since been received from Pegu, from 

 Major Berdmore. 



Although I have attended pretty regularly the Calcutta fish-bazars 

 during the last year, and have procured many good specimens, and added 

 largely to our collection of fish-skeletons, the only species new to the 

 museum which have been obtained are Serranus lanceolatus, C. and 

 V. (small), Gerres poet^e, C. and V., and Otolithus maculatus, C. 

 and V. (four individuals).* I have procured, however, a fine series of a 

 somewhat rare fish which is perhaps the Chrysophrts longispinis, C. 

 and V., apud Bleeker, from Calcutta ; but the dentition of which differs 

 altogether from that of Chrysophrts, there being no palatal teeth, but 

 only a band of "card-like" teeth in each jaw, with reverted tips, especially 

 those in the upper jaw in front, which are much curved backwards. Now 

 the teeth of Chr. longispinis are described in the Mist, des Poissons 

 to be " small, and disposed in three ranges." Our species otherwise 

 approximates the Chr. calamara (Russell, pi. 92), but is less deep in the 

 body, the eye is larger and is situate higher in the head, which last is 

 throughout covered with small indistinct scales. Pre-operculum minutely 

 toothed ; mouth slightly protrusile. The dorsal spines are alternately 

 stouter and more slender, as in Ruppell's figure of Chrysophrys saeba, 

 and also in Datnia and Datnioides, Bleeker (founded on the Coius 

 polota of Buchanan Hamilton ).f
