8 PEKCID.E. 



Colour in life bright red, with four or five darker cross bands ; a darker red patch on 

 the forehead, from the base of the first dorsal spine to the snout, including the eye. 

 Another similarly coloured band from snout above the maxillary to the angle of the 

 prasoperculum. The spinous portion of the dorsal, and sometimes the caudal, black- 

 edged ; the soft dorsal with a yellowish margin. 



Dr. Bleeker and Prof. Peters regard Perca fasciata (Forsk.) or Serranus ocean icus 

 (Lacep.) merely as a variety of coloration of this species.

Caudalis rounded. Canine teeth very small. Prasoperculum distinctly serrated, 

 with a very shallow notch above the angle. The third to the sixth dorsal spines 

 are the longest, rather feeble, not quite one-third the length of the head. The 

 height of the body is contained thrice and two-thirds, and the length of the head 

 three times in the total length. The diameter of the eye is one-sixth of the length of 

 the head. The upper maxillary bone reaches beyond a vertical from the posterior 

 margin of the orbit. 



Head, body, and fins brown ; the trunk and vertical fins covered with very small, 

 round, white dots, each being smaller than a scale. The head is nearly immaculate. 

 There is a blackish streak above the maxillary bone. 



Note. — This is clearly the S. summana of Forskal, who describes it as covered with 

 guttw, not with macular, and with hardly any on the head. There are two specimens 

 in the British Museum, received from Dr. Riippell, with the name of S. summana ; but 

 these are identical with S. tumilabris of this collection [122].
