Notes on Epinephelus nigritus, Caulolatilus microps, and Coryphaena hippurus
Proceedings of the United States National Museum
The middle of the back is not so much elevated as iu P. millleri. The leugth of the head is slii^htly more than oue-third of the total without caudal. The eye is twice as long as the snout, and about two-fifths as long as the head. The maxilla is about one-half as long as the head and its posterior extremity is very much widened. The mandible is slightly longer than the maxilla, its length being nearly one-half the greatest height of the body. The width of the interorbital space equals one-half
... the length of the maxilla. The greatest height of the body equals two-fifths of the total length to caudal base. The least height of the tail equals the width of the interorbital area. The origin of the dorsal is slightly behind the vertical through the origin of the ventral, the distance from tip of snout to the origin of the dorsal being not much more than the length of the anal base. The longest dorsal ray slightly exceeds one-half the length of the head. The length of the dorsal base equals the length of the mandible. The origin of the dorsal fin is considerably in advance of the middle of the total length. The origin of the anal fin is -directly under the end of the dorsal. The length of the anal base equals the greatest height of the body, and is not much in excess of the length of the head. The origin of the ventral is almost directly undw that of the dorsal. The third ray of the ventral is as long as the eye. The pectoral is one-fourth as long as the total without caudal. The caudal fin is too imperfect to be described. Two of the species taken on hand-lines and brought in fresh are referred to in the following paper. One of these is a smallish' example of the black grouper, Ejyineplielus nigritus, which weighed 32 pounds after evisceration. Because of the comparative rarity of small specimens of this grouper, and also because of the doubt recently expressed by my friend, Professor Jordan, concerning the distinctness of nigritus from morio, the arrival of a fine young example from a region which is rather outside of its customary range is both interesting and opportune. After studying.the Albatross specimen I am strengthened in my opinion that nigritus and morio are by no means identical, if, indeed, they may eveu be considered as closely related.
