Eutropius macropthalmos, nobis, n. s. Of the usual form of 

 this genus, bufc witb remarkably large ejes, that occupy more tban 

 half of tbe beigbt of the bead. Longer maxillary cirri reacbing to 

 tbe vent, the four inferior cirri to base of pectorals : spines slender, 

 the pectoral less so, and all minutely pectinated behind ; the dorsal 

 also jagged in front for its basal half. 



D. 1-7.— A. 47 to 54. 



Colour bright silvery, infuscated along the back, with a golden 

 lustre on the gill-covers. Soft rays of the dorsal and pectorals infus-

 caudal, while several outer rays of the caudal above and below are 

 white throughout. Ventrals and anal white : the slender adipose 

 fin having minute dusky spots. Longest specimen 6|- in. Tenasserim. 



Siluricthys Berdmorei, nobis, n. s. Maxillary cirri reaching to 

 base of ventrals, the inferior to base of pectorals. The upper javv 

 slightly longer than the lower. Eyes small. Dorsal fin slight and 

 slender, but seeming to consist of three or four rays. Pectoral spine 

 short, only half of the length of the fin. 



D. 3 or 4.— A. about 65. P. 1-13.— V. 11.— C. 17. 



Anal continuous with the caudal, but distinctly defined. General 

 colour dull olive-brown, paler below. Length of specimen 4f in., 

 by i in. deep at dorsal. Head f in. Tenasserim. 



Psetjdosiltjrtts macropthalmos, nobis, Ti. s. General form of 

 Ps. iabda, (B. TL.,microcep7ialus, Blkr), but proportionally less deep 

 and more elongated, with eye of twice the diameter, and the lower 

 jaw closing evenly with the upper, or very nearly so, though protrud- 

 ing when the mouth is open ; maxillary cirri much longer, reacliing 

 far beyond the more developed pectorals ; the anterior bands of teeth 

 above and below much less broad, and the palatal teeth reduced to 

 two straight and well detached transverse patches. 



D. 4.— A. 75.— P. 1-13.— V. 7.— O. 19 or 20. 



Colour dull silvery, much embrowned, especially above, with a 

 greenish tinge, probably more decided in the recent fish. Length of
