and continued on to the end of the caudal. Vertical fins of striking 

 laeight, extremely weak and slender. The longest dorsal i-ays, which 

 are near the middle of the fin are equal to the head-length in height, 

 and the longest anal rays are slightly longer. The interneural and 

 interhasmal spines are very elongate. The pectoral is much more 

 developed on the coloured side, where if laid forward it reaches to the 

 vertical from the hinder edge of the upper (posterior) orbit. 



The ventrals are distinct from the anal : the left is more expanded 

 than the right. 



The caudal is long and pointed, being contained five times in the 

 total : it has 17 rays. 



Colours in life. Transparent white with minute black dots. Three 

 narrow black lines along the body, one of which is the lateral line, while 

 the otliers follow the lines of origin of the interneural and interhremal 

 spines respectively. Vertical fins black with irregular milk-white 

 blotches. Left ventral bliiok. Left pectoral grey tipped with black. 

 On the right side, owing to the transparency of the body, the three black 

 lines of the coloured side shew through. Length, 3| inches. 



Two specimens were taken in 68 fathoms 16 miles B. of the month 

 of the Devi river in the Malianaddi delta, from a soft bottom of very fine 

 sand. The second species of Scianectes will be described among the fishes 

 from a deeper and more open part of the Bay.

 mud, but also on hard sand.

This species resembles Solea hartzfeldii (Giinther, Cat. iv. 471, 

 and Bleeker, Atlas. Ichth. torn, vi, p. 25, pi. ccxlvi, fig. ],), from 

 which it differs in the form and ariangement of the dorsal and ventral 

 fins, in the proportions of the head to the body, and in coloration. 



Body ovate, its height one-third of the total length. Head with a 

 symmetrically rounded profile, its height being a little gi-eater than its 

 length, which is nearly 4J in the total. The snout forms a I'ostral hook, 

 which curves round behind the symphysis of the lower jaw, touching 

 the vertical from the front edge of the anterior eye. Eyes situated in 

 the middle of the head, the upper half-way in advance of the lower : 

 their diameter is Q\ in the head-length, and they are about half a 

 diameter apart.
