The dorsal fins and tail are greenisli umber-brown, 

 adipose pale greenish, tipped with red, — the for-

 pectoral and ventral fins are greyish brown; the 

 anal is greenish brown at the base, bordered with a 

 rather broad border of clear red. Iris is coloured 

 yellow. The lateral line seems straight, except a 

 slight undulation at its commencement ; the mouth

S. UNDULATUS, WaVE-LINED SaW-BELLIED SAL- 

 MON. — L. Geral, Chidova. Schomh. Drawings^ 

 No. 52. — Tlie drawings of this small species show 

 a different proportion from the last. The head is 

 proportionally much longer, the under jaw projects, 

 and both are armed with rather strong teeth. The 

 dorsal outline is undulated to a less degree than the 

 last, but the adipose fin is situate remote from the 

 tail, and rather nearest to the dorsal. Another re- 

 markable peculiarity is in the lateral line performing 

 three distinct undulations in its length, as in the 

 line below.
