PLEURONICHTHYS OCELLATUS Starks and Thompson, new species. 



The nearest relative of this species is Pleuronichthys ritteri, from 

 which it may be known by the presence of a very conspicuous spot

ocellated with milk white midway on the lateral line between the 

 base of the caudal and the snout; by its fewer number of gill-rakers; 

 its greater number of scales; the greater long diameter of its upper 

 orbit, and its interorbital spine a little higher, sharper, and less 

 inclined to bend downward. 



Head from 3§ to 4| in length of body without caudal; depth '_> 

 to 2\. Long diameter of upper orbit '1 to "J, 7 ,, in head: distance 

 across both orbits two in head; length of maxillary '.\\ to 1; length 

 of caudal peduncle, measured to marginal caudal rays, from (i to 7 1; 

 its depth two. Number of dorsal rays from 61 to 7'_ > ; anal rays 11 

 to 50; scales in series below lateral line from 84 to 91; gill-rakers 3 

 or 4 + 7 to 9. 



The dorsal contour of body outlines broken conspicuously at the 

 upper orbit by the projecting snout. The interorbital ridge is 

 trenchant, narrow, and rather low. The spine on its posterior part
