494 Annals of the South. African. Museum. 



Two specimens : A male fi'om Little Namaqualand (coll. P6nn- 

 guey) and a female from Port Elizabeth (coll. Moorhouse). 



A very distinct species, without special affinity to any of those 

 previously known. 



Pachydactylus purcelli. 



Head much depressed ; snout a little longer than the orliit ; ear- 

 opening oval, oblique. Digits short, feebly dilated distally, the 

 dilated part with 5 or G lamellae. Head and body covered with 

 uniform flat granules, largest on the snout ; ventral scales flat, sub- 

 imbricate, larger than dorsals. Eostral nearly twice as broad as 

 deep, entering the nostril ; 8 to 10 upper labials ; as many lower 

 la])ials, the anterior as large as or a little larger than the sym- 

 physial, which is twice as long as broad. Pale brownish above, 

 with darker marblings or vermicular spots, which may form more or 

 less regular cross-bands. 



Total length, 85 mm.; from snout to vent, 40; head, 11; fore 

 hmb, 13 ; hind hmb, 16. 



Several specimens from Touw's Eiver (coll. Purceh) and from 

 Little Namaqualand (coll. Schlechter). 



The very flat head and the position of the nostril well distinguish 

 this species from all its congeners. 



ZONURUS MACROPHOLIS. 



Head-shields very rugose ; nasals not swollen, in contact, the 

 nostril in its posterior part, close to the first upper labial and the 

 aiiterior loreal ; frontonasal tetragonal ; praefrontals forming a 

 suture ; interparietal tetragonal, betw^een the two pairs of parietals 

 and touching the frontoparietals ; temporals strongly keeled, the 

 posterior forming short spines ; lower eyelid scaly ; four or five 

 upper labials ; five lower labials, bordered by four large, striated, 

 and keeled shields ; gular scales large, imbricate, strongly keeled, 

 sharply pointed. Dorsal scales very large, forming regular trans- 

 verse series, rugose, strongly keeled, denticulate posteriorly, the 

 keels terminating in a short spine, on the flanks similar ; 17 trans- 

 verse series from occiput to base of tail, the largest containing 14 

 scales ; a distinct lateral fold. Ventral scales smooth, quadrangular, 

 the outer pointed behind, in 10 longitudinal and about 20 transverse 

 series. A pair of enlarged posterior praeanal scales. Limbs with 

 large spinose, serrated scales. 9 femoral pores on each side. Tail 

 with w^horls of large, rugose, strongly keeled, spinose, serrated
