Carnegie Institution of Washington publication. 56 Papers from the Department of Marine Biology. the large, rather deeply forked caudal fin, of which the upper lobe is generally slightly the larger. The appearance of this fish gives one the idea of speed and power in about equal proportions. It is of the type of the battle cruiser. The body of the fish is well panoplied with fairly large cycloid scales. The eyes are large and staring, and are placed about the center of the upper lateral region. The anterior nostril is a small pore at the front end of the supraorbital ridge; the posterior is a slit ( inch long in a 3 feet 10 inch specimen) standing nearly vertical (slightly forward and downward) in front of the eye. Our American authorities (Jordan and Evermann, and Evermann and Marsh) state that the lateral line is straight, but their figure shows that it rises slightly just above the pectoral fin. In my specimens, for the most part, this rise was far.

In my largest specimen, however, the rise was only moderately pronounced. As was noted above, 12 large specimens have been taken and exam- ined, but the fish being so characteristic in structure and markings that it is recognized at a mere glance, fin ray count was made for only one specimen. This fish, an adult, 3 feet 10 inches in length, had dorsal rays v-i, 9; and, i, 8. Jordan and Evermann (1896) give D. v-i, 9; A. i, 9; but their figure has only 8 anal rays. Evermann and Marsh, in their "Fishes of Porto Rico" (1900), make the dorsal rays v-i, 10; and the anal ones i, 8; yet they copy Jordan and Evermann's figure referred to, which has but 9 soft rays in the dorsal. Possibly there is some variation in the number of fin rays. The figure referred to is reproduced herein as text-figure 2. The table on page 58 gives the comparative
