THE LIZARDS OF THE GENUS TACHYDROMUS. 235 
series of small scales anteriorly. Ventral plates in 6 longitudinal series, only the 
outer keeled ; 28 transverse series. Sides minutely granular. 42 plates and granules 
round the middle of the body. Preanal plate rather small, bordered by one semi- 
circle of small smooth plates. 
Upper surface of limbs with rhombic keeled scales. 4 femoral pores on each 
side.' 23 lamellar scales under the fourth toe. 
Caudal scales strongly keeled and shortly mucronate, the whorls alternately a 
little longer and shorter, the fourth containing 18 scales. 
Olive-brown above, the dorso-lateral area (two rows of plates) lighter; two 
biackish streaks, formed of spots close together, along the middle of the back ; a 
blackish tateral band, from the nostril, through the eye and involving the upper half 
of the ear-opening, to the base of the tail, dotted with whitish on the body; repro- 
duced tail reddish. Lower parts white. 
The specimen selected as the type is thus described by Van Denburgh :— 
“The colour above is greenish olive, becoming lighter yellowish olive on the 
limbs and tail. The sides are dark olive brown. A light line, edged above with 
dark brown, starts at the nostril, crosses the lower eyelid, the lower part of the ear- 
opening, and fades away above the axilla. The upper labials, dorsals, limbs and tail 
are dotted or spotted with dark brown. ‘The lower surfaces are greenish white, 
tinged with orange on the tail.”

Habitat. This remarkable species was described from 13 specimens from Kan- 
shirei and Taipeh, Formosa ; one of these is now preserved in the British Museum. 
It has since been reported from Southern China, near Canton, by T. Vogt. 
Tachydromus chinensis, T. Vogt, Sitzb. Ges. Nat. Fr. Berl. 1914, p. 98, is said to 
be similar to P. kuehnei, but there are only 3 pairs of chin-shields and the ventral 
plates are obtusely keeled. 3 femoral pores on each side.—Northern parts of the 
Province Kuangtung, Southern China. 
Apeltonotus, g. n. 
Head-shields normal. Nostril pierced between the nasal, a postnasal, and the 
first upper labial. J,ower eyelid scaly. Collar distinct. Dorsal scales small, hexago- 
nal, subimbricate, keeled; ventral plates obtusely pointed, imbricate, of median 
rows smooth or faintly keeled, of outer row strongly keeled. Digits compressed, with 
1 Of the 13 types and co-types, 8 have 4 pores, 4 have 5, and 1 has 4—5.—3 or 4 pores in specimens from Canton 
according to Vogt.
