CHELONODON Miller. 
241. Chelonodon patoca Hamilton-Buchanan. Batete. 
Five specimens from Manila, 3 to 6 inches long. 
Family GOBIDA. 
ELEOTRIS Gronow. 
242. Eleotris fusca (Bloch & Schneider). 
The scales in this species are 55-60 in longitudinal series. Its habitat is from the East Indies to 
Tahiti. It is not found in Hawaii, where it is represented by the small-scaled Eleotris sandwichensis. 
Eleotris sandwichensis Vaillant & Sauvage, of the streams of Hawaii, has 70 to 80 scales, but is otherwise 
identical with the present species. 
Of this species we have four examples, from 3 to 4 inches long, from Sibuyan and Aparri (northern 
Luzon). 
OPHIOCARA Gill. 
2438. Ophiocara aporos (Bleeker). Pazo. 
Dorsal vi-t, 9; scales 30-34; scales on top of head large, about 15 rows in front of dorsal; maxillary 
reaching scarcely beyond vertical from front of orbit; posterior border of preopercle with two inconspic- 
uous pores; a mid-lateral row of large spots on trunk and caudal peduncle, more or less confluent into 
a narrow band, of a width equal to diameter of eye; above is another indefinite series of similar spots; 
cheek and opercle crossed by three oblique bands of dusky, the upper band continuing lengthwise across 
the base of the pectoral, being bordered above and below by whitish, and fusing posteriorly with a 
transverse band of dusky which crosses the bases of the pectoral rays; dorsal and anal margined with 
pale; anal in males with a crimson band across base, outside of which, near middle of fin, is a narrower 
band, pale bluish in preserved specimens, probably violet in life; spots at base of pectoral indistinct 
in female. 
Two specimens, a male and a female, 7 inches long, from Mindoro Island; a male 5 inches long 
from Sibuyan, and a large male, 8.50 inches long, from Camp Balete, Rio Baco, Mindoro (above tide). 
Ophiocara hedti (Bleeker) may not be different from this species. 
244. Ophiocara porocephala (Cuvier & Valenciennes). 
Dorsal vi-1, 8; scales 40-42; scales on top of head small, about 25 rows in front of dorsal; maxillary 
reaching vertical from middle of orbit; posterior border of preopercle with three large pores; scales of 
trunk for the most part each with a squarish dark spot at base; soft dorsal, caudal, anal, and ventrals 
edged with pale. Life colors: Black above; sides with slight green tinge; belly white, thickly 
speckled with dusky; dorsal, anal, and caudal narrowly edged with pale yellow. 
One specimen from Mindoro Island, 4.50 inches long, and one from Calayan, in a brackish estuary, 
6 inches. 
A specimen of this species, taken at Calayan, was left dry for more than half a day, and revived 
upon being placed in water. 
Ophiocara ophiocephala (Kuhl & Van Hasselt, in Cuvier & Valenciennes) is probably not distinct 
trom the present species. leotris ophiocephala of Day is not this species, being a fish with a small 
mouth, and with the scales on top of head large, 15 in front of dorsal. The name porocephala has page 
priority over ophiocephala. 
BUTIS Bleeker. 
245. Butis koilomatodon (Bleeker). 
Eleotris koilomatodon Bleeker, Verh. Bat. Gen., xxm, 1849, 21 (Cantor cited this memoir in his Catalogue of Malayan Fishes, 
giving it priority); Maduras Straits. 
Eleotris caperatus Cantor, Cat. Mal. Fishes, 197, 1850; Sea of Pinang. 
Prionobutis serrifrons Rutter, Proc. Ac. Nat. Sci. Phila., 1897, 84; Swatow, China. 
Head 3.25; depth 4.30; eye 3.75; dorsal vi-9; anal 9; scales 29; superorbital crests strongly ser- 
rated; two anteriorly converging serrated ridges in front of each eye, as in other species of Butis; mouth 
oblique, making an angle of about 40 degrees with the horizontal axis.
