SHORE FISHES OF THE HAWAIIAN ISLANDS. 
TROPIDICHTHYIDJE. 
191. Tropidichthys jactator Jenkins. Honolulu; Laysan Island. 
As was stated by Dr. Jenkins," this species is very similar to T. punctatissimus (Gunther). 6 Its 
distinction rests on a difference in the color pattern, the spots being fewer and generally more widely 
separated than those of T. punctatissimus. The distended belly, an alleged distinctive character seen 
in the type specimen of T. jactator, is merely the result of its having been preserved while distended 
with air. In 3 specimens from Laysan Island, measuring 65, 78, and 93 mm., respectively, the 
spots on the sides of the head are nearly as large as those on the body; those on the upper part of the 
snout are about half as large; there are 7 or 8 on a line between upper part of eye and tip of snout. 
Those on the snout and upper part of head and nape are narrowly bordered with dark brown. On 
the body there are about 13 spots in a line between the dorsal and anal fins, and 6 in a vertical line 
near the middle of caudal peduncle. The largest example has an indefinite dark spot below the 
base of dorsal tin. In life the spots are light blue. Most of them are as large as the pupil and so close 
together that the brown ground color appears as a network. 
Three examples from the reef at Honolulu measure 37 mm. The spots on the upper part of the 
snout and head are very small. There are 5 in a line between upper part of eye and tip of snout. 
They are ocellated, as are also the spots along the back to the base of dorsal. There are 7 or 8 spots 
in a line between anal and dorsal fins, and 4 in a vertical line near middle of caudal peduncle. The 
cotype collected by Dr. Jenkins in Honolulu also has large spots on the snout. 
T. punctatissimus, represented by 8 specimens from Panama, has from 7 to 10 small ocellated spots 
in a line on upper part of snout. The spots on the back from nape to base of caudal are small and 
have dark margins. There are from 11 to 23 spots between anal and dorsal and from 8 to 15 on the 
caudal peduncle. One example has 4 short lines extending backward from the eye. A specimen 
from the Galapagos Islands referable to T. punctatissimus has the spots on the sides of the snout fused, 
forming vertical bands. There are 3 short bands or elongate spots radiating backward from the eye. 
OSTRACIID^. 
192. Ostracion camurum Jenkins. Puako Bay, Hawaii. 
193. Ostracion oahuensis Jordan & Evermann. Honolulu. 
194. Ostracion lentiginosum Bloch & Schneider. Honolulu. 
195. Lactoria galeodon Jenkins. Honolulu. 
Several specimens were taken from the stomach of a Coryphxna. 
DI0D0NTID JE. 
196. Diodon hystrix Linn'eus. Honolulu. 
197. Diodon holocanthus Linmeus. Laysan Island. 
One specimen 235 mm. long. The fins are immaculate. There are 10 or 12 small dusky spots 
scattered over the body. A broad, dark bar, interrupted in the middle, extends between the eyes. 
There is a similar bar on the nape, a spot as large as the eye above and behind the pectoral, a median 
brown bar on the back anterior to the dorsal, and a blotch surrounding the base of the dorsal. 
198. Chilomycterus aflfinis Gunther. Honolulu. 
SC0RP£NID£. 
199. Sebastopsis kelloggi Jenkins. Honolulu. 
200. Sebastopsis parvipinnis Garrett. Honolulu. 
201. Merinthe maerocephala (Sauvage). Honolulu. 
Two specimens. D. xn, 11; A. in, 5. Orbital tentacles barred with dusky; in one specimen they 
reach the base of third dorsal spine when depressed, in the other they measure 1.66 times diameter of 
eye, not reaching base of first dorsal spine; second anal spine large and heavy, a deep groove running 
lengthwise of each side. 
202. Sebastapistes corallicola Jenkins. Honolulu; Hilo. 
a Tropidichthys jactator Jenkins, Bull. U. S. Fish Com. for 1899 (June 8, 1901), 399. 
b Tetrodon punctatissimus Gunther, Cat. Fish. Brit. Mus. 1870, viii, 302.
