Greer (1985) mentions the presence of four preanal pores on each side of the anal opening in the only female he examined (MNHP 35417). In this connection it should be noted that these pores were not observed in any of the 5 specimens I examined (3 males and 2 females). This character is apparently not constant in D. bourreti. Field Notes.—All the D. bourreti specimens currently known were caught under stones or wood debris on the ground of a tropical forest at an elevation of 450- 900 m. Liu and Hu (1962) found two specimens in China on the surface of the ground in a hilly forest. In discussing the milky white coloration on the end part of the tail in D. bourreti, it should be observed that this species can also be characterized as having a comparatively very long tail, its length reaching 40% or more of the SVL in both males and females (in other representatives of the genus the length of the tail does not exceed 20-25% of the SVL). The long tail with a bright coloration at its end contrasting sharply with the dark unicolored body of the animal may qualify as a good example of attractive coloration. My observations show that in case of danger (when the stone under which the animal hides is lifted) a Dibamus abruptly B FIG. 4.
