157. Coryphaena hippurus Linnseus. Common Dolphin. u Mahihi;” “ ifahimiihi.” Fig. 79. 
Head 4.35 in length; depth 5; eye 6.2 in head; snout 3; interorbital' 3; maxillary 2.1; D. 57; A. 27. 
Body long and slender, deepest anteriorly; anterior profile in adult, male nearly vertical; maxillary 
reaching posterior edge of pupil; mouth large, horizontal; hands of teeth on jaws, vomer, tongue, anti 
palatines, the teeth all recurved, those in outer row larger, being wide-set, sharp, anti conic; tongue 
rounded, free; eye low, anterior; a horizontal groove from eye to nostril; origin of dorsal over middle 
of eye in adult male, its tips extending to rudimentary rays of caudal, the twelfth or thirteenth ray 
being the highest; origin of anal nearer posterior edge, of eye titan base of caudal; ventrals inserted 
slightly behind upper base of pectoral, 1.25 in head; pectoral 1.35. 
Color in alcohol, bluish silvery above, lighter below, becoming white on belly; the sides, chiefly 
below lateral line, with many dark spots about size of pupil, these most numerous anteriorly; dorsal 
fin dull purplish black; other fins color of corresponding parts of body except ventrals, which are dull 
purplish black on inner side; anal dull purplish on outer edge; peritoneum grayish black. 
This description is from a specimen (No. 04450) 29.5 inches long, front Honolulu. Numerous 
other examples were seen by ns and several were preserved. One from Hilo, when fresh, had the 
lower half of body yellowish; blue spots under pectorals; jet black spots all over the rest of the lower 
side, upper portion bluish with dark spots on silvery bluish ground; dorsal fin bright ultramarine, 
blue; belly light; anal tinged with blue. The color of this fish in life is indescribably beautiful, but 
it undergoes very rapid changes while dying. After death only faint indications of the former colors 
remain. Our several specimens are 29 to 46 inches in length, from the largest of which the following 
measurements were secured:
