Show 18/3.] FROM CELEBES AND THE PHILIPPINE ISLANDS. 169 Oxycalamus oxycephalus. STENOGNATHUS MODESTUS, D. & B. Rhabdosoma leporinum, Giinth. Col. Snak. p. 12, is identical with this species, as already indicated by Peters, Berl. Monatsber. 1861, p. 684. Seven or eight upper labials. Dumeril's statement that this snake is found in Java, is probably erroneous, as several other undoubtedly Philippine snakes have been stated by him to be from Java, where they do not occur. OLIGODON NOTOSPILUS. (Plate XVIII. fig. A.) Scales in fifteen rows. Loreal small but distinct; one prae- and one postocular; seven upper labials, the third and fourth entering the orbit; temporals 1 + 2. Ventral shields 143; anal entire; subcaudals 35 (the seven anterior not divided). Blackish ash, many scales with a very small white dot; along the median line of the back a series of eighteen large rhombic yellow black-edged spots, three of which belong to the tail. Head yellow, with two angular black cross bands. Lower parts uniform yellowish. A single example of this beautiful snake was obtained by Dr. Meyer on Mindanao ; it is 10| inches long, of which the tail takes l|inch. COMPSOSOMA MELANURUM (Schleg.). Dr. Meyer bas obtained several examples of a light-coloured variety with reddish tail in Luzon and Negros. This variety is mentioned by Dumeril & Bibron (p. 301), and is again described by them as Plagiodon erythrurus (p. 175) from Java. Several other Philippine reptiles having been erroneously stated by Dumeril ^ & Bibron to have been obtained from Java, 1 doubt whether the typical example of their Pl. erythrurus was received from that island. In Jan's ' Iconographie' this snake is also figured twice, under the names given by Dumeril and Bibron. ZAOCYS LUZONENSIS. Scales smooth, in fourteen rows, a single elongate loreal; occipitals truncated behind ; seven upper labials, of which the third and fourth enter the orbit; the fifth triangular, with its upper point not reaching the postocular or the temporal; two praeoculars, the lower small, |
