140 Report on some Fishes received from Sitang River. [No. 2, 



Sci^ka lucida, Richardson, figured in the Zoology of the Voyage of 

 H. M. S. ' Sulphur,' and is therefore probably that cited as figured 

 in one of the unpublished drawings of Gen. Hardwicke in the British 

 Museum, No. 130; the Sc. lucida inhabiting the Chinese Seas. 

 The eyes, however, are smaller than in Scijenoides lucida, the teeth 

 more developed, the medial caudal rays are prolonged into a length- 

 ened filament (which, however, may be characteristic of youth), and 

 the fore-part of the back is smooth and spineless. It has also many 

 more rays to the second dorsal and fewer to the anal fins. 



B 9— 1-43— A 2-7. 



Length to end of caudal filament under 2 in., in all hitherto 

 examined. Colour bright silvery with white fins. 



4. Sc. (?) .aspee, nobis, n. s. Another small fish common at the 

 mouths of the Gangetic rivers, with body and fins like the last, but 

 the back less elevated, and the anal spine considerably more deve- 

 loped. Mouth large, opening obliquely upward ; the teeth moderate 

 or rather small. Head with many prickles or spinelets, more or less 

 developed in different individuals. Eyes placed high, near the plane of 

 the forehead, on which two slight ridges — one from above each eye — 

 meet behind upon the occiput at a somewhat acute angle. Some have 

 a mesial spinelet, pointing a little backward, on and above the move- 

 able and protrusile portion of the upper jaw, and another directed 

 forward a little behind it : other spinelets, again, are seen (or more 

 readily felt) on a raised line posterior to the eye, another upon each 

 side of the occiput, and there are spinelets likewise at the margin of 

 the pre-opercule. 



J). 9—1-28. A. 2-6. 



Colour silvery, the head brilliant silvery in the recent fish, with 

 more or less of a nigrescent wash on the dorsal and the caudal fins, 

 and numerous very minute dark specks near the ridge of the back, 

 which are likewise seen in Sc. Haedwickii. Length mostly under 

 3 in. 



5. Otolithus maculatus, Kuhl and von Hasselt (nee apud Can- 

 tor). This is clearly the species described by this name in the Sis- 

 toire des Poissons, with numerous black spots on the caudal and
