170 PEECIDJB, 



teeth are arranged at a right angle ; the band of palatine teeth is 

 short and narrow. The upper maxillary is styliform at its upper 

 end only, and soon becomes broad, but is scarcely broader at its lower 

 end thap in the middle ; it appears to reach behind the middle of 

 the eye — perhaps to the posterior margin of the orbit. The eye is 

 placed high up the side of the head, interfering with the upper outline 

 of the head, and is of moderate size, its diameter being 5^ in the 

 length of the head. Operculum with tlu'ce spines : the middle is 

 the largest, flat, and much projecting; the upper is similar, but 

 smaller ; the lower is more distant, very small, and nearly hidden 

 by the skin. The prseoperculum is rounded, and armed behind with 

 coarse, irregular, obtuse spinous teeth ; the sub- and intcroperculum 

 appear to be entire. The specimen is so prepared that the branchio- 

 stegals may be seen ; there are on one side distinctly seven, but on 

 the other I count six only. 



The spinous dorsal is connected Avith the soft by a distinct mem- 

 brane ; its base is miich longer than that of the soft — nearly as long 

 as the body is high. The spines are strong ; the third is the longest, 

 about half the length of the base of the spinous fin. There are seven 

 spines — an eighth apparently belonging to the soft dorsal. The first 

 spine is the shortest, and equal to the eighth ; the second and fourth 

 are not much lower than the third. The soft dorsal has been rounded, 

 and is rather higher than the spinous. The caudal rounded. The anal 

 has three spines in front, the second of which is strongest and rather 

 curved, but scarcely longer than the third. Pectoral and ventral fins 

 rounded ; the base of the spine of the latter falls just below the root 

 of the former. 



The scales must have been very small and thin, and imbedded 

 in the skin, as in the Tench. The coloration is reddish brown on 

 the back, lighter beneath ; all the parts, except the upper portion of 

 the spinous dorsal, are covered with small, round, yellowish-white 

 spots, each of which, on the body, may have corresponded in life to 

 a scale. There is a large brown blotch in front of the dorsal, 

 between the occiput and the operculum ; a second smaller one extends 

 below the fourth to the sixth dorsal spine ; a thii-d below the middle 

 of the soft dorsal ; a fourth on the back of the tail.
