The observation of this ornament in this species and in C. oustaleti is contrary to the description of Bourgat & Brygoo (1968), who recorded tufts of superimposed papillae in some of the specimens they examined.

No additional ornaments could be discerned. Next to pedunculi and auriculae Ramanantsoa (1978) recorded the presence of a tuft of superimposed papillae at the sulcal base of each pedunculus and the presence of a single median den- ticulated ridge ('auricule medio-sommitale, denticulee'). Fig. 15 a & b. Hemipenis of B. platyceps, a = sulcal view, b = lateral view. Brookesia platyceps (Günther, 1893) (Fig. 15 a and b) RMB 25342 Rud Gorge, Mlanje, Malawi The hemipenes closely resemble those of B. p. carri described by Loveridge (1953). Hemipenes stoutly built and truncated. Pedicel, truncus and apex cannot be distinguished, because calyces and the capitate condition are absent. Two curved apical horns are present, each with a row of papillae. *) It would be interesting to find out whether this variability in papillate structures correlates with the karyotypic variability within these two species (see section karyology below). An affirmative answer to this question combined with information as to the geographical distribution of the varieties could make a reconsideration of the specific unity of C. oustaleti and C. verucosus nesessary (cf. also Bourgat 1973).. a b.
