146 Report on some Fishes received from Sit any River. [No. 2, 



of the total length : the pectorals reaching to the middle of the body. 

 The lower jaw when closed exceeds in length and rises to the same 

 plane as the upper ; and in both jaws there is a row of larger teeth 

 bordering the usual band of small teeth. Genital appendage rather 

 long. 



J). 6-10.— A. 9. 



Colour greenish-albescent, much embrowned above ; all the fins 

 much speckled, the variegation shewing as numerous pale dots upon 

 the caudal. Longest specimen 4f in. Port Blair, Andaman Islands. 



E. incerta, nobis, n. s. This is a species very similar to the last, 

 and which is commonly brought to the Calcutta fish-bazars ; but I 

 have not known it to exceed 3 in. (or at most 3i in.) in length, and 

 the head is more than a quarter of the total length. In an example 

 3-| in. long, the head to point of gill-cover measures |- in. In a few 

 specimens — one or two thus characterized may generally be selected 

 from two or three dozens — the curious feature occurs of a sharp re- 

 flected spine at the angle of the prse-opercle. In E. belobrais'Cha, 

 C. V., such spines occur on two of the gill-rays. The groove from 

 the eye to the angle of the prse-opercle exists, but the naked line is 

 more contracted than in E. caviprons. Dentition as in the latter, 

 but the teeth are proportionally smaller. Fin-rays the same. Colour 

 dull olive-brown, the pectorals whitish and minutely speckled, having 

 a dusky spot at their base ahove, which does not occur in E. cati- 

 profs : dorsals, anal, and caudal, infuscated, the second dorsal pret- 

 tily speckled with whitish and the other fins less distinctly variegat- 

 ed. Length mostly under 3 in. 



E. scintillans, nobis, ii. s. A species with only eight rays to the 

 second dorsal and 6 (or perhaps 7) to the anal fins. General aspect 

 very much that of an Ophicephalus. Form short, the head nearly 

 a third of the total length. Colour dull pale green, infuscated above 

 and at the sides, with an appearance of two black spots above and 

 below at base of tail ; all the fins being inconspicuously speckled. As 

 seen in spirit, many of the scales have a brilliant golden sparkle. 

 Length of only specimen 2J- in. Port Blair, Andamans. 



E. feliceps, nobis, n. s. Species remarkable for the approxima- 

 tion of the eyes, which are separated by an interspace only one-fourth 

 of the diameter of the orbit. Scales, as in the preceding species,
