211. Ostracion oahuensis Jordan & Evermann. “ Momoawaa.” 
Head 3.9 in length; depth 2.9; eye 2.9 in head; snout 1.2; preorbital 1.6; interorbital 1 ; D. 9; A. 9; 
P. 10; C. 10. Body 4-sided; dorsal side of carapace evenly convex, its greatest width one-fourth greater 
than head; lateral dorsal angles not trenchant, slightly convex anteriorly, then evenly convex; snout 
blunt, the anterior profile ascending abruptly, then strongly convex in front of eyes; interorbital space 
nearly flat; cheek flat; side of body concave, its width about equal to head; ventral keel prominent, 
evenly convex; ventral surface nearly flat posteriorly, but little convex anteriorly, its greatest width 
1.4 times length of head, its length just twice its width; gill-opening short, not exceeding two-thirds 
diameter of eye; least width of anterior opening of carapace 1.75 in interorbital or 1.5 times diameter 
of orbit, the depth nearly twice orbit; mouth small; teeth rich brown; least depth of posterior opening 
of carapace much less than width of anterior opening, equaling distance from lower edge of preorbital 
to pupil; length of caudal peduncle less than that of head, its depth 2.2 in its length; no spines anv- 
where; dorsal fin high, its edge obliquely rounded, its length 1.3 in head; anal similar to dorsal, the 
edge rounded, its length 1.2 in dorsal; caudal slightly rounded, its rays nearly equal to head; pectoral 
with its free edge oblique, the rays successively shorter, length of fin equal to height of dorsal. 
Color in life, dark brown with blue tinges; interorbital space showing more or less golden; small 
whitish spots profusely covering entire dorsal surface; no spots on side of body or on face; no spots on 
ventral surface except a faint one of a slightly darker color than general gray color of surface; one 
longitudinal row of golden spots on each side of upper part of caudal peduncle from carapace to base 
of caudal fin; pectoral, anal and dorsal fins with transverse rows of faint spots; caudal bluish black at 
base, white on posterior half; a broad light or yellowish area below eye; iris golden. 
Color in life, upper parts dark brown, with shades of olive; belly brown; sides of body, back, tail 
and caudal fin covered with bright blue spots, mingled with which are dark brown spots; face and top 
of head and snout with bright blue lines, between which in region of the eyes is golden; cheeks and 
below with close-set dark blue lines and with dots, the color of which is nearly white; base of anal blue; 
outer portions of dorsal, anal and pectorals transparent, with golden tinge, a very brightly colored fish. 
Color in alcohol, rich brown above, sides darker, ventral surface paler, brownish about margins, 
dusky yellowish within; entire back with numerous small, roundish, bluish-white spots; upper half of 
caudal peduncle with similar but larger spots; forehead and snout dark brown; lips brownish-black; 
cheek dirty yellowish; sides and ventral surface wholly unspotted; base of caudal blackish, paler 
distally, the dark extending farthest on outer rays; other fins dusky, with some obscure brownish spots. 
This species is related to 0. camurum Jenkins, from which it differs in the smaller, more numerous 
spots on back, the entire absence of spots on side, the smaller size of the spots on the caudal peduncle, 
and the brighter yellow of the suborbital region. Only 2 specimens known, both from Honolulu. 
Type, No. 50668, U. S. N. M. (field No. 03443), a specimen 5.6 inches long, obtained by Jordan & 
Evermann, July 25, 1901. Cotype, No. 7478, L. S. Jr. Univ. Mus. (field No. 2156), 5.25 inches long, 
collected at Honolulu in 1898 by Dr. Wood. The species was not obtained by me.

212. Ostracion lentiginosum Bloch & Schneider. 
Two specimens (5 and 5.43 inches in length) obtained by me on the coral reef at Honolulu. 
Ostracion lentiginosum Bloch & Schneider, Syst. Ichthv., 501, 1801, Indies. 
Ostracion punctatus Steindachner, Denks. Ak. Wiss. Wien, lxx, 517, 1900 (Honolulu). 
213. Lactoria galeodon Jenkins, new species. 
Head 2.8 in length; depth 2; eye 2 in head; snout 4.5; interorbital 1.2; D. 9; P. 11; A. 8. Cara- 
pace 4-sided; a pair of long, slender, slightly divergent spines, their direction slightly upward; a 
similar pair terminating the lateral ventral angles, horizontal and not divergent; middle of back 
with a strong, compressed, triangular spine, notched on posterior border, projecting slightly backward, 
and resembling a shark tooth; snout short, the anterior profile concave; dorsal lateral angles little 
convex, the ventral angles more convex; 12 plates along its edge from snout to spine; 8 plates in lateral 
dorsal angle, no spine at its middle; ventral surface with 11 or 12 plates in longitudinal median series 
7 in transverse series.
