white markings occur on the na])e. hehind the eye. and on th.e cheek: dorsal and 

 caudal with dark pencillings lietween the rays. 



Yoiituj (figure 31). .\ small exanijile -|.i nnn. long, differs in heing much 

 more elongate, its depth being J 07 in the length to the hypural joint: the caudal 

 fin is distinctly longer than in the adults, and the eye is larger: the first spine is 

 much shorter than the second, and is terminated by a bunch of tentacles of 

 various sizes : its cutaneous appendages are less numerous than in larger exam])les. 

 which, however, may be due to its imperfect preservation. 



Colour variation. Another specimen. 113 mm. long, differs from the adults 

 described above in its colour-marking, which consists of an almost uniform 

 lighter and darker marbling over the head and body: the dorsal and anal fins 

 each bear a broad, dark inframarginal liand. and the caudal has about three rows 

 of dark, inter-radial spots on its distal half.

Skin either smootli or with microscopic spicules: teeth large, cardiform. and 

 depressible : they are arranged in several rows on the anterior ])ortion of each 

 jaw. and form two groups on the vomer; palatine and lingual teeth also present: 

 dorsal spines separate, the first with a slender, naked rod ; second and third 

 spines enveloped in thick skin, and either well-develoijed or merely tubercular: 

 soft dorsal high and long, with 14-15 rays, the last almost or quite united with 

 the tail by membrane : anal opposite the end of the dorsal, with 8-9 rays, the last 

 more or less united to the caudal base : gill-opening a small pore below the middle 

 of the pseudobrachium : mucigerous system defined by minute pores with skinny 

 tentacles on each side of them : they form a lateral line which is arched from the 

 shoulder to above the anal fin, and is lost on the lower portion of the tail ; others 

 are arranged in regular series on the head.
