 and a-half times in its length ; orbit four and one-third times in 

 the length of the head. Head very thick and very broad, entirely 

 covered with large scales ; teeth rather large for the genus, 

 numerous, and disposed on a line on each jaw ; scales large, num-

 other at their base ; the second dorsal is formed of one spine and 

 eight branched rays ; the caudal is strongly emarginated, of four-

 part covered with small scales ; the anal is formed of three spines 

 and eight soft rays ; the ventrals are situated on the line of the
