Lefua andrewsi Fowler. Type. Lefua costata (Kessler) Head contained 4 to 4% times in length to caudal base; depth Qji to 6^- Dorsal II, 6, i; anal ii, 5, i. Scales 93 to 102 in median lateral series. Snout 2% to 3^8 in head; eye 4% to 6%; maxillary 3% to 4:%; interorbital 3 to 3}^. Scales with 38 to 43 radiating marginal striae (30 to 36 in type of Nemachilus dixoni); circuh rather fine, moderate. Color in alcohol brownish generally, with sUght oUve tint. Back and sides with very obscure scattered moderate spots of small size. Dorsal and caudal finely and obscurely spotted with gray-brown, though latter fin always with distinct round black spot at middle of base, not larger than pupil. Iris dull slaty, lips and jaws all pale or duU. Dark median lateral streak not very distinct and largely evident only after ventral. Length 40 to 73 mm. Six from Hsing Lung Shan. In the Academy the type of Nemachilus dixoni, a synonym of the present species, is included above. Elxis nikkonis Jordan and Fowler^ is certainly closely related, though the alleged larger scales, given as about fity-six, would seem to warrant specific distinction. It is, however, otherwise closely related, as the black basal caudal spot suggests. Lefua Jordan and Richardson^ is based on three young examples only 38 to 45 mm. long. It is represented with four barbels in profile, showing it doubtless had eight. Its coloration greatly suggests Misgurnus decemcirrosus (Basilewsky). Nemachilus variegatus (Dabry) Sauvage and de Thiersant^ is probably a Lefua. It is described as having large brownish cloudings formed into a series of somewhat un
