Only about 80 specimens of Freshwater Fishes were collected, which are referable to 14 species, 4 being described as new. The localities are the same as enumerated in m y previous paper, with the exception of the Lolak River, which runs a little to the west of the Dumoga River, in the kingdom of Bolang Mongondo, and Lake Lahendang in Minahassa. 1.

Depth of body 4 to 5 times in total length, length of head 3-3j. Head as broad as deep, 1| as long as broad ; upper jaw not projecting beyond the lower, maxillary extending to below anterior border of eye ; diameter of eye 4-4| times in length of head, 15 interorbital width ; opercles and occiput scaled; rest of head naked, with the sensory lines very distinct. Dorsal VI, 9; first dorsal nearly equally distant from the end of the snout and the base of the caudal; longest rays of second dorsal half length of head or a little less. Anal 9, opposite to soft dorsal. Ventral reaching the vent, or narrowly separated from it. Caudal peduncle twice as long as deep ; caudal obtusely pointed. Scales 48-50; 16-20 in a transverse series. Yellowish brown to dark brown above, without markings ; fins brown to blackish ; ventrals sometimes whitish. Total length 80 millim. 14 specimens from L. Posso, C. Celebes. 3. GOBIUS LATIFRONS, sp. n. (Plate XXVIII. fig. 2.) No canine teeth. Depth of body 4|-5 times in total length, length of head 3j to 3|. Head broader than deep, 1| as long as broad; upper jaw not projecting beyond the lower, maxillary extending to below anterior border of eye; diameter of eye 4 to 4| times in length of head, as long as snout, equal to interorbital space, which is concave ; opercles and occiput scaled, rest of head naked. Dorsal VI, 9 ; first dorsal nearly equally distant from the end of the snout and the base of the caudal; longest rays of second dorsal | to f length of head. Anal 8, opposite to soft dorsal. Ventral widely separated from vent. Caudal peduncle twice as long as deep; caudal rounded. Scales 34-35; 15 or 16 in a transverse series. Olive, with more or less distinct dark brown spots, which may form a zigzag on each side of the body; fins greyish or brown : a black spot on the first dorsal.
