MR. G. A. BOULEXGER ON FISHES, BATRACHIAXS. [May 6, 



longest, between femorals shortest ; gular sliields smallei- than 

 anals ; axillary and inguinal shields rather large. Beak scarcely 

 hooked ; a large frontal and a pair of prfefrontal shields. Fore 

 limbs with moderately large imbricate scales of veiy unequal 

 size, the largest raised and nail-like ; no enlarged tubercles on 

 the back of the thighs ; fore limb with five claws, hind limb with 

 four. Carapace black, each shield with a yellowish-brown areola; 

 plastron black and yellow, with a median yellowish marking with 

 dentate borders and speckled with olive-grey; head and limbs 

 dark olive, the horny sheath of the jaws, the claws, and the 

 larger scales on the fore limbs yellowish. 



Length of carapace 93 millim. 



A single female specimen. 



This very distinct species is most nearly related to H. signatus 

 Walb., from which it difiers,' apart from the coloration, in the 

 large frontal shield and the absence of a laige conical tubei'cle on 

 the back of the thigh. 



3. Lygodactylus capensis Smith. 



4. Pachydactylus affinis Blgr. 



Several specimens, from between Umtali and Mai'andellas, 

 enable me to supplement the description of this Gecko given in 

 1896^ from a single specimen obtained in the Rustenberg district 

 of the Transvaal. 



Naso-rostrals in contact; 8 to 10 upper labials; 7 lower 

 labials. Tail feebly depressed, tapering to a fine point, covered 

 with equal smooth scales, which ai'e hexagonal and juxtaposed on 

 the upper surf ace, roundish and subimbricate on the lower surface. 

 Pale brown above, with I'ound blackish spots inteimixed with 

 smaller round white spots ; a blackish streak on each side of the 

 head, passing through the eye ; lower parts white.

8. Platysaurus guttatus Smith, 



A male specimen, measuring 110 millim. from snout to vent, 

 tail 170. Difiers from the type in having the fi'onto- nasal 

 forming a short suture with the rostral, separating the nasals, 

 and in the absence of a shield between the interparietal and tlie 

 occipital, which are in contact with each other. 18 femoral pores
