“Dorsal fins not very elevated, continuous, but with a slight depres- 
sion at the point of union of the two; a dentate flap above each eye; 
lateral lines of pores 5, only three of which extend to the basis of the 
caudal fin, viz, the second, third, and fifth; the first extends to opposite 
the middle of the second dorsal; the fourth commences below and in 
front of the basis of the pectoral, and extends to a point a little behind 
that measured by the extremity of that fin ; the inferior series of oppo- 
site sides converge and unite a little behind the basis of the ventrals
