Show 1883.] GECKOS OF N E W CALEDONIA. 125 Brussels Museum, the other in tbe Lisbon Museum) and a tbe British Museum). 8. RHACODACTYLUS AUBRYANUS. *Rhacodactylus aubryanus, Bocage, Jorn. Sc. Lisb. iv. p. 202, and 1881, p. 127. Agrees in every respect with the preceding, except in having the upper surface of the head covered with minute granules, not larger than those covering the back. From snout to vent 195 millim. I have examined the unique specimen of this form, belonging to tbe Lisbon Museum, and, in spite of its very great resemblance to R. leachianus, believe it to deserve, at least till we get other specimens for comparison, specific distinction. 9. RHACODACTYLUS CHAHOUA. (Plate XXI. figs. 1, la, \ b, 1 c, 1 d.) * Platydactylus chahoua, Bavay, Cat. p. 3. General proportions of R. trachyrhynchus.

Male with three short series of femoral pores on each side; these do not extend beyond the inner half of the thighs, and are separated from the corre- 16 sponding series on the other side ; I count is pores on each side, r ° 5 or 6 there being, besides, one or two pores indicating a fourth series ; altogether 79 pores.
