Show 1869.J FRESHWATER FISHES OF BURMA. 617 Eyes situated opposite the angle of the mouth, a portion being on the lower surface of the head. Diameter \ of length of head, 14j diameter from end of snout, 2 diameters apart. Nape of neck elevated. The width of the head equals its length without the snout, and is the same as its height. Gape of mouth wide, cleft equals half its gape ; lower jaw strongly prominent. Maxillary cirri reach as far as the posterior margin of the orbit; mandibular pair opposite the angle of the mouth and minute. Teeth villiform in both jaws, and in an interrupted band on the vomer. Fins. Dorsal arises above the ventrals. Pectoral spine weak, entire, as long as the head without the snout. Anal reaches the base of the caudal, but is separated from it by a notch. Caudal deeply forked. Colours. Silvery, spotted all over with fine black dots, giving it a dark cloudy appearance. A black finger-mark on the side above the base of the pectoral fin. Caudal lobes with black tips. Hab. Throughout the branches of the Irrawaddi, in the Pegu aud Sittoung rivers. Out of many specimens, the largest was 6-L inches long. In one the mandibular cirri were absent, but it was evidently the same species. The Pseudeutropius taakree, Sykes, or the P. longimanus, Giinther, is tolerably abundant in the Irrawaddi and its branches-as is also the P. goongwaree, Sykes, or Eutropius monophthalmus, Blyth. The former has been fully described by Dr. Gunther (Catalogue of Fishes, vol. v. p. 60); the latter has still some points which require investigation, although it is doubtless Bagrus exodon, C. & V. PSEUDEUTROPIUS GOONGWAREE, Sykes. D. || 0. P. 1/8. V. 8. A. 46-54. C. 17. Length of head nearly i), of pectoral 4., of caudal 1, height of body nearly ^ of the total length. Eyes behind the cleft of the mouth, and partly on the lower surface of the head. Diameter | of length of head, 11 diameter from end of snout, 2\ diameters apart. Rostral cirri as long as the head; maxillary reaching the anal fin ; external mandibular pair slightly the longest, and extending to the base of the pectoral fin. The longitudinal furrow on the head extends to the base of the occipital process, which is narrow, and of nearly equal width throughout. The cleft of the mouth extends halfway to the orbit; upper jaw slightly the longest, anteriorly rounded. Teeth villiform in the lower jaw and over the lower surface of the snout, so as to be entirely beyond the lower jaw. Palatine teeth in a narrow uninterrupted curved band. Fins. Dorsal spine somewhat slender, as long as the head without the snout, finely serrated posteriorly. Pectoral spine about the same length, stronger, and coarsely denticulated along its whole internal |
