 light spots scattered irregularly over the sides ; head dark ; dorsal, anal, 

 and ventral fins covered with fine black points ; in some specimens the 

 dorsals and anal quite dark; pectorals plainer; caudal similar to ventrals; 

 "the cranium is depressed and flattish behind the orbits, without distinct 

 median keel on occiput or on interorbital area. The form of the head is 

 as in typical (lobitis, the occiput abruptly widened behind the eyes; the 

 ridges also similar, the orbital ridge bounding the orbit behind as well as 

 above the eye and joining the temporal ridge laterally." (Gilbert MS.)
