940 SURGEON F. DAY ON NEW riSHKS OF MADRAS. [NoV. 28, 



Colours. Silvery grey, becoming dirty white along the abdomen. 

 First dorsal tipped witli black ; second dorsal greyish, lightest along 

 its centre. Pectorals, ventrals, and anal yellowish. Caudal tinged 

 with grey. 



I have referred this to Bloch's species, although he gives the 

 dorsal formulary as follows :— D. 8 | Jj ; but his engraving shows 

 X), 9 1 1, and the first short spine is evidently omitted. This would 

 give D. 10 I ^, as I find to be the case at Madras. His specimen 

 was received from Tranquebar.
