Br. 7 ; D. viii-ix. 11 ; A. 11 ; P. 20-21 ; V. i. 5 ; C. 11 ; L. lat. 

 54. Head 2.7-2.8 in the length to the hypural. Eye 4.7-5.7 in 

 the head, and 1.6-1,7 in the snout, which is 2.8-3.2 in the head. 

 Ir.terorbital space 3.1-4.5 in the eye. Third dorsal spine 2.5 in 

 the head. 



The ridges of the head are prominent and smooth, and ter- 

 minate in strong spines. A strong anterior orbital spine ; 

 posterior half of supraorbital ridge with about four small spines. 

 Interorbital space deeply concave. Two postocular spines on 

 each side, from the inner of which a series of radiating ridges 

 extends backwards. A low median ridge and a prominent medio- 

 lateral spine on each side of it. From the outer postocular spine 

 a broken ridge extends backwards to the suprascapular which is 

 armed with three strong spines. Snout unarmed. Bony stay of 

 cheek with two spines, the first a little before the middle of the eye 

 and the second below its hinder margin. Preoperculum armed with 

 two short spines of which the upper is slightly the longer, and 

 about equal to the width of the interorbital space. Opercular 

 ridges smooth, terminating in strong spines. 



Fig. 14. Insidiator parilia. Head and teeth. 



Anterior nostril with a short tentacle, posterior tubular ; no 

 supraocular tentacle. A large skinny lobe on the lower border 

 of the operculum. Teeth minute, subequal, the inner ones a 

 little larger than the others. They form a broad band on the 

 upper jaw and a narrower one on the lower; two parallel bands 

 on the vomer and a narrow one on each palatine. 



Body covered with ctenoid scales which extend forward onto 

 the operculum and postorbital portion of the preoperculum ; 

 those of the lateral line are not enlarged and are unarmed. 

 There are 90-105 or 00-67 rows above the lateral line according 

 to the direction in which they are counted.
