1860.] Report on some Fishes received from the Sitang lliver. 103 



tinged with dusky in the young. Length 4 in., by rather more than 

 1 in. in depth. Tenasserim. 



N. albolineata, nobis, n. s. Both broader and deeper in the 

 body than N. danrxca, (B. H.), with the rauzzle scarcely upturned, 

 and a longer anal fin — more immediately approximating the species 

 to Perilampus (as restricted). Upper filaments reaching to the 

 tips of the pectorals, which latter do not reach to the base of the 

 ventrals ; the base of the dorsal is scarcely anterior to that of the 

 anal ; ventrals somewhat short. 



D. 9.— A. 10. 



Colour olive-green on the upper half, buífy-white below, with a 

 broadish white stripe along the hind-half of the body chiefly, narro w- 

 ing anteriorly, and more or less distinctly bordered by a blackish 

 stripe above and another below, the lower more developed and becom- 

 ing conspicuous towards the tail. A fuscous tinge on the pectoral 

 fins ; the other fins colourless, or perhaps yellowish. Length 2 in. or 

 less. Tenasserim. 



Perilampus eulvescens, nobis, n. s. A species without cirri, 

 and deep in the body, much resembling in form the P. loyokula, 

 (B. H., v. P. psilopterus, McClelland), but having longer and more 

 pointed pectorals reaching nearly to the anal. 



D. IQ.—A. 22. 



Colour (in spirit) dull fulvous, with a just perceptible narro w dark 

 lateral streak, a litt.le more decided towards the tail : infra-orbital 

 plates and gill-covers bright silvery : irides yellow. Tins white, with 

 a faint nigrescent wash, especially on the tail ; the first ray of the 

 ventrals much lengthened, as in certain affined species. Length 2| 

 in. Tenasserim. 



P. aeetnis, nobis, n. s. Greatly resembles P. lineolatus, nobis 

 (J, A. S. XXV II, 289) ; but is a degree more typical, with the head 

 distinctly upturned, and the anterior base of the dorsal is less 

 forward, being more nearly parallel with that of the ventrals. It 

 has also 13 dorsal and 16 anal rays, instead of 12 and 14. Markino-s 

 obsolete on the anterior third of body, but the medial streak to base 

 of tail very dark, bordered by a narrow palé streak above and by 

 anotber below, and the dark one above this, again, broader than in P, 

 lineolatus. Length 2f in. Tenasserim.
