. Bonn zoological bulletin. Zoology. Fig. 18. Afronatrix anoscopus, unicoloured specimen from Mt. Nimba (Photo: C. Brede). Guinea exceeds that of our series in most of the data tak- en. A modern revision including also the central African populations seems highly desirable. - Nutrition: Of the 42 specimens from Ziama Forest, on- ly three individuals had full stomachs (with fishes), viz. ZFMK 56066 (Aplocheilichthys schioetzi), 56076 (Krib- ia cf. nana), and 56275 {Aplocheilichthys schioetzi and unidentifiable frog remains).

Grayia smithii (Leach, 1818) Material examined: ZFMK 56036, adult female, south of Seredou: Malweta village, W. Bohme coll. 6-26 Oct. 1993; photographic voucher: a big, light-coloured road- killed specimen from the road between Seredou and Zoboroma, W. Butzler phot. March 1995. Remarks: This specimen had several fishes (Tilapia (Coptodon) ) in its stomach. The bad shape of the fishes from the stomach of this snake does not allow a pre- cise identification, but it seems likely that they belong to an undescribed species (J. Freyhof, pers. comm.). Another big female of this species, likewise from Malwe- ta village, was left for the PROGERFOR teaching collec- tion at Fig. 19. A fronatrix anoscopus, patterned specimen from Pic de Fon (Photo: C. Brede). Natriciteres variegata (Peters, 1861) Material examined: ZFMK 56097-099, Ziama Forest south of Seredou: Malweta village, W. Bohme coll. 6-26 Oct. 1993; ZFMK 56257-258, Seredou, W. Butzler coll. Nov. 1993; ZFMK 56262-263, Malweta village, W. But- zler coll. Nov. 1993; ZFMK 58622 and 60579, Seredou, W. Butzler coll. 1994 and 1995 re- spectively. Remarks: With nine specimens the third most common snake species in WB's Ziama Forest survey. Psammophiidae Psamtnophis phillipsi (Hallowell, 1844) Material examined: ZFMK 56047, Ziama Forest south of Seredou: Malweta village, W. Bohme coll. 6-26 Oct. 1993; ZFMK 60792, Seredou, W. Butzler coll. June/Aug. 1995. Remarks: Both spec
