Two New Species of Caribbean Deep-Dwelling Jawfishes (Opistognathus, Opistognathidae)

Abstract

Measurements are all straight-line measurements between points made with dial calipers. All measurements involving snout tip originate at the mid-dorsal point of upper lip. Caudal and procurrent rays are reported as a two-part formula, the first figure refers to rays associated with the dorsal hypural and the second figure refers to rays associated with the ventral hypural. The number of lateral scale rows reported are only approximations because of their irregularity and frequent absence. The first lateral scale row counted is the one just touching or just posterior to the upper posterior end of the opercular flap. The last two rays in the dorsal and anal fins have their bases closely approximated, share a common pterygiophore, and were counted as one ray.
