CGLONOTUS Peters, 
61. Celonotus leiaspis (Bleeker). 
One example from Mindoro Island, 6 inches long, and one from Sibuyan, 4.50 inches. These have 
the dorsal rays 55, situated on 15 rings, 4 of which belong to the body; body rings 17; tail rings 31; body 
smooth and rounded except for the dorsal ridges, on which character, combined with the long dorsal 
fin, Kaup’s genus Celonotus was founded. Doctor Giinther’s specimen of C. leiaspis had the dorsal 
fin standing on twelve rings. 
DORYRHAMPHUS Kaup. 
62. Doryrhamphus macgregori Jordan & Richardson, new species. 
Head 5.2 in length without caudal, greatest depth of body equal to length of postorbital portion of 
head; length of tail less than body, equal to length of last 17 body rings; rings of trunk 19, of tail 22; 
dorsal rays 27; the base of the fin .80 of head; spines at edges of body rings evident, but not prominent; 
lateral line continuous, passing into the lower caudal edge; snout 1.25 times postorbital part of head, 
the eye twice in same distance; interorbital space concave; behind the eyes, on occiput and nape, an 
Fic. 7.—Doryrhamphus macgregori, new species. Type. 
elevated median longitudinal ridge; lower sides of snout with two longitudinal raised edges, connected 
by numerous low and slight transverse keels; operculum with a slightly oblique median raised keel, 
from which radiate obliquely downward about 8 lesser raised lines; pectoral fin short, about equal to 
eye; color in spirits uniform dark brown; caudal with a whitish posterior edge. 
Here described from a single specimen, 1.50 inches long, the type, no. 20202 U.S. National Museum, 
from Calayan. The specimen is probably a female. 
Except for the much larger number of tail rings, this species seems closely to resemble Doryrhamphus 
pleurotenia (Giinther). 
GASTEROTOKEUS Heckel. 
63. Gasterotokeus biaculeatus (Bloch). Dwmdam. 
Three examples from Cuyo, 6 and 7 inches long. General color in life grass green, finely speckled 
with pale blue; along side of head and tube some mottling of pink; eggs pale brown. 
HIPPOCAMPUS Linnezus. 
64. Hippocampus kuda Bleeker. 
One example, 5 inches long, from Mindoro Island, agreeing with the specimen recorded by Jordan 
& Seale from Cavite. The specimens we have called H. kuda differ from H. aterrimus Jordan & Snyder 
in color, in their smoother body, with less prominent tubercles and without tentacles. in their longer 
snout and relatively longer body; and in the form of the coronet and lesser prominence of the head 
tubercles, which bear no tentacles. The length of the snout is nearly exactly equal to the distance 
from the front of the orbit to the anterior rim of the nuchal pore. In HH. aterrimus the snout is shorter, 
though apparently variable in length, being never greater in our specimens than the distance from 
the posterior (not anterior) rim of the orbit to the nuchal pore. In H. aterrimus the depression on the 
top of the coronet is distinctly 5-sided, being bounded in front by two prominent points, while in H. kuda 
the rim of the depression is triangular, the two anterior points not being developed. The head and 
snout of H. aterrimus is striped with gray, in H. kuda speckled with black. The difference in relative 
length of the body, while difficult to measure, is evident to the eye on comparison of specimens of the 
same size. The specimens from southern Negros called H. kuda by Jordan & Seale are not that species,
