. Bulletin - United States National Museum. Science. Figure 86.—Mystus havmolleri H. M. Smith. Drawn by Nai Chote Suvatti; courtesy of the Thailand Government. It is believed that M. stigmaturus Fowler, described from six speci- mens to 8 cm. long, is this fish, the only difference mentioned by Fowler being in the color pattern. His specimens, larger than the type of M. havmolleri^ seem to represent simply a later, and probably more typical, arrangement of the markings. The vernacular name in the Trang district is pla hayeng khao. MYSTUS CAVASIUS (Hamilton) Pimelodus cavashts Hamilton, 188
