Length of head 3|, of caudal 7J, height of body 7 in the total 

 length. Eyes diameter 4| in length of head, 1| diam. from 

 end of snout, and about \ apart. Interorbital space concave. 

 Width of head between preopercular scales equal to about | its 

 length. Supraorbital margin with six strong deriticulations, and 

 the ridge from it to occiput with about five more ; ridge from eye 

 to shoulder with about five spines : that from preorbital to pre- 

 opercular spine with six (besides being serrated). A small spine 

 on inner side of front nostril, which is furnished with a cirrus. 

 Spine at angle of preopercle reaching to the base of the pectoral, 

 a short spine -below succeeded by another still more minute. 

 Teeth villiform, in two parallel patches on vomer, and in a narrow 

 band along either palatine. Fins second dorsal spine | length of 

 head, and nearly as high as commencement of second dorsal fin. Pec- 

 toral | length of head, ventral slightly longer. Anal commences 

 below second ray of dorsal ; caudal cut square. Scales those on the 

 head not spiny. Lateral line with about 15 small spines in the 

 first portion of its course. Colour brownish above, becoming dull 

 white beneath, first dorsal and end of caudal darkish, second dorsal

 Length of head 3|, of caudal 7, height of body 7 in the total 

 length. Eyes superior, diameter 6| to 7 in length of head, 1| diam. 

 from end of snout, and 2 apart. Head strongly depressed, its 

 upper surface triangular, the base between the preopercular spines | 

 of the length. Interorbital space flat or slightly concave, two ridges 

 extending back from orbit, the inner dividing over the occiput, 

 whilst the outer or temporal terminates at the shoulder in two 

 blade-like spines. One spine at anterior lower angle of orbit, 

 none at nostrils, which are patent but not tubular. Preorbital with 

 three raised grooves starting in a stellate form from a common 

 centre. Preopercle with most of its surface forming a portion of 

 the flattened upper plane of the head, and having two very strong 

 spines at its angle, the inferior of which is the longer and some-
