Abstract

Nicaraguensis very closely resembles leucas by the following characters. The anterior margin of the eye is posterior to the front of the mouth by a distance equal to half its own diameter in nicaraguensis; the gill openings are relatively somewhat longer in nicaraguensis, the third being nearly as long as the distance between the nostrils; the free tip of the second dorsal is about two-thirds as long as its base in nicaraguensis.
