 longer and more slender than the others. 



Color. Yellowish brown, much darker above, lighter on sides, and 

 light yellow on under part and sides of head, belly and under part of 

 tail. Three longitudinal very dark brown lines on each side : the 

 upper commencing near the middle of top of head and following 

 along the back to base of caudal fin ; the middle one commencing al 

 the nostril and passing through the eye to upper portion of opercu- 

 lurn, thence about in the centre of side to about the centre of base of 

 caudal fin; the lower commences under the pectoral fin and follows 

 the ventral curve of the body td the base of caudal fin. All three 

 lines are darkest and broadest forward, and- terminate as a series 

 of nearly confluent clots on the tail. Central rays of the caudal dark 

 brown, outer rays uncolored. Dorsal, anal and pectorals not colored.

Habits. Nothing is known concerning the habits of this species, 

 the only speaimeus observed being the three mentioned. From the 

 fact of its having a single ovary containing a small number (about 60) 

 of large eggs it is probable that it is viviparous.
