1896.] FISHES MADE BY DR. A. D. SMITH. 221 
shorter than the eye, in a very narrow band. The maxillary barbels 
reach to the end of the humeral spine and are lined with a narrow 
membrane interiorly. Mandibulary barbels reaching to the root 
of the pectoral, provided with numerous long fringes. Nuchal 
carapace tectiform, obtusely rounded behind, its end reaching to 
below the first soft dorsal ray. Humeral spine not quite extending 
so far backward, much longer than high, with its upper margin 
deeply excised, terminating in a sharp point. 
Adipose fin rather long, the interspace between it and the 
dorsal being less than the base of the latter. Dorsal spine ser- 
rated anteriorly, shorter than the pectoral spine, which is strongly 
serrated along both edges and equal to the distance of the foremost 
part of the soft part of the trunk from the snout. Dorsal and 
pectoral spines and the caudal lobes produced into filaments. 
Coloration uniform.

A single specimen, 30 cm. long, was obtained on Jan. 19, 1895, 
at Geledi ou the Shebeli. 
This fish is closely allied to S. serratus, but sufficiently distin- 
guished by the different form and outline of the cephalic carapace.
