The pectorals are large and wide, reaching backwards to the anus and second dorsal. The 

 first dorsal, commencing opposite to the tip of the gill-cover, is high anteriorly and rounds off 

 gradually posteriorly, its membrane terminating exactly at, the base of the second dorsal. The 

 spinous ray of the ventral is short and not easily distinguishable from the first soft ray to which 

 it is applied. 



Skin. — The top of the head is sprinkled with little soft conical pimples, and on the body 

 and posterior surfaces of the pectoral rays there are a number of small circular scales, whose 

 surfaces, and particularly their posterior margins, are studded with very short minute spines. 

 The general tint of the upper parts of the fish is dark-brown, which is mixed on the top 

 of the head with large clay-coloured patches, and on the gill-covers, nape, and pectorals, 

 with crimson-red blotches; there are also some smaller spots of the latter on the back. The 

 sides, belly, and pectoral and ventral fins are ornamented by perfectly circular spots as big as 

 the point of the finger, of dead-white, generally bounded by a ring darker than the neighbour- 

 ing skin. Some of the white spots on the pectorals are placed excenti ically on a larger 

 orange-coloured mark, and there is a row of large orange spots on the under surface of the 

 tail. The dorsal fins are blackish with oblique dull, yellowish, irregular spots or bars. On 

 the anal the yellowish bars alternate more distinctly with the purplish-black ones, there being 

 three of each; and on the caudal there are three transverse rows of contiguous, large, black 

 spots on a yellowish ground, with indications of a fourth row on the tips of the rays. The 

 colours of the female specimen are much less brilliant. 



Intestines. — The stomach is a bag with folds towards its fundus, and minute reticulated 

 wrinkles round the pylorus, where its parietes are thickened. The linings of the oesophagus 

 and stomach have a very different appearance, and are separated by a distinct line. There 

 are seven long cylindrical pyloric caeca. The liver is very large, and after long immersion in 

 spirits retains a bright scarlet colour.
