702 MR. F. DAY ON NEW INDIAN FISHES. [June 27, 



Scales in oblique rows, passing backwards and upwards above the 

 lateral line, and in horizontal rows below it. Some exist over dorsal 

 and anal rays. 



Lateral line follows the curve of the back in the upper fourth of 

 its course ; it is in single tubes. 



Colours. Rosy, with four oblique brilliant golden lines passing 

 from the lateral line upwards and backwards, impinging on two rows 

 of scales, leaving two intermediate rows without such lines. Four 

 similar golden lines are also present below the lateral line : the first 

 proceeding from the posterior margin of the orbit to the lateral 

 finger-mark ; the second from the middle of the operculum to op- 

 posite the end of the soft dorsal, where it is lost on the lateral line ; 

 the third from beneath the orbit to the base of the caudal fin ; the 

 fourth from the lower margin of the base of the pectoral to the base 

 of the anal. A large, deep black finger-mark exists on the lateral 

 line opposite to the commencement of the soft dorsal. Pectoral, 

 ventral, and anal yellowish. Dorsal and caudal pinkish. Eyes 

 silvery, with a dark mark below the pupil. 



Following the opinion of Cuvier and others, and not having seen a 

 specimen of Russell's fish, I had previously considered this to be the 

 Genyoroge notata, C. & V. Since my arrival in Madras I have had 

 ample opportunities of investigating the species, which I find to be 

 a Mesoprion, and apparently the M. russelli of Dr. Bleeker. 



Upeneoides BiviTTATUs, Cuv. & Val. 



This fish is very similar to the U. vittatus, C. & V., with which, 

 indeed. Dr. Giinther has placed it. But there are certain evident 

 differences, which I propose adverting to. 



Its barbules extend to beyond the posterior margin of the oper- 

 culum ; its caudal is more deeply lobed ; its lateral line is more 

 raised ; and it possesses a rather thick and large air-bladder, which 

 the U. vittatus is without. 



The coloration likewise differs. The Upeneoides bivittatus is 

 darker along the back ; its golden stripes are not so well marked ; 

 and the caudal has two horizontal brown lines on either side of its 

 centre, and three oblique bands running across the upper lobe and 

 two across the lower lobe. 



In the Upeneoides vittatus the caudal has six yellowish-brown 

 bars with dark edges across the upper lobe, and a black extremity, 

 whilst on the lower lobe there are also three oblique bars, and the 

 extremity is white. The first dorsal is also black-edged. 



Ukanoscopus marmoratus, C. & V.
