153. Uranoscopus guttatus ? 



The specimen is about four inches long; it resembles Uranoscopus filibarbis , 

 Cuv. et Val., in having a filamentary process hanging from beneath the 

 symphysis of the lower jaw, and in having only four spines at the lower 

 margin of the praoperculum ; but the head and back are marked with 

 round white spots, as in U. guttatus, Cuv. et Val., those on the head 

 being very numerous and small, and the scales are arranged in oblique- 

 transverse lines the whole length of the body.

155. Uranoscopus. 



This species, like Uranoscopus lavis, Bloch, Schn., has a smooth skin, 

 without scales, but the inferior margin of the praeoperculum has five 

 spines, and those of the scapula are scarcely visible. The single dorsal 

 fin commences as far forwards as the upper angles of the operctilum. 

 The sculpture of the head has nothing remarkable. The colour is greyish 

 brown.

 Its flesh and spawn are much esteemed for food. It is remarkable for the 

 absence of the air-bladder, a part of which is found in all the other 

 known species of Polynemus.
