upper branch extending beyond tip of first ray, a distance which is 
contained two and one-half times in length of the latter; ventrals in- 
serted midway between base of caudal and posterior margin of eye; 
reaching posteriorly almost to end of base of anal; tip of fin formed 
by end of third ray. Insertion of dorsal anterior to that of anal, 
almost midway between the latter and bases of ventrals; the second 
ray longest, 2745 in head; the other rays consecutively shorter; the 
last when depressed reaching a point midway between its base and 
that of caudal; base of fin contained 14 in head. Anal similar in 
shape to dorsal, the longest (second) ray contained three times in 
head. Gillrakers on lower half-of arch, 15, flat and acutely pointed,

Color metallic steel blue above, sides and lower surfaces pearly 
white; dorsal edges of upper four or five pectoral rays dusky; the 
lower ones dusky at bases and toward tips, the middle portions light, 
giving the effect of a median light -area on ventral surface of fin; 
upper edge of base of pectoral dusky; dorsal and anal immaculate; 
eaudal dusky, with a broad, slightly darker margin; anterior rays 
of ventral slightly dusky above; upper part of axil of fin dusky. 
One speciment, the type, Cat. No. 62229, U.S.N.M., measuring 350 
mm., was obtained by Doctor Jordan, it having flown aboard the 
steamer J/oana some miles to the westward of Walpole Island, the 
nearest land otherwise being the New Hebrides. | 
Named for James Douglas Ogilby, of Brisbane, Australia, who 
assisted us in comparison of this example with the flying fishes known 
from Australia.
