Variation. — I have at hand six specimens from Mount Mari- 

 veles, Bataan, and fourteen from Isabela, Occidental Negros. 

 The scale rows vary between twenty-six and twenty-eight, 

 (twenty-four to twenty-eight, according to Boulenger) . The tail 

 is a little longer than head and body when intact. Younger 

 specimens have the belly scales keeled rather strongly. 



Remarks. — I have found this species common in the two local- 

 ities mentioned, but have failed to find it elswhere. The type 

 was collected by H. Cuming, the exact type locality not known. 

 These lizards live along small mountain streams, and are usually 

 found under partly submerged rocks or logs; they readily dive 

 under water when disturbed and take refuge under completely 

 submerged objects. Their extremely spiny appearance makes 

 them easily recognizable. 



The species is also reported from Celebes by de Rooij. 



TROPIDOPHORUS PARTELLOI Stejneger 



Tropidophorus partelloi Stejneger, Proc. U. S. Nat. Mus. 39 (1911) 97. 

 Description of type. — (From Stejneger.) "Upper head shields 

 smooth; fronto-nasal broader than long; prefrontals broadly in 

 contact; frontal as long as fronto-parietals and interparietal 

 together, in contact with two anterior supraoculars; five supra- 

 oculars, first longest, fifth smallest, second in contact with fronto- 

 parietal; two anterior supraciliaries larger, followed by five 

 very small ones, none behind the suture between third and 

 fourth supraocular; fronto-parietals separate, shorter than in- 

 terparietal ; parietals not in contact behind interparietal ; nostril 

 a round hole in the middle of a single nasal, which is followed 

 by two loreals one behind the other; behind the orbit three ver- 

 tical rows of small scales followed by two rows of large temporal 

 shields; between these and the unprotected ear-opening several 

 rows of scales keeled vertically ; seven supralabials, the anterior 

 four low and slightly increasing in size backward, the fifth sud- 

 denly much higher, but not much wider, sixth and seventh nearly 

 as large; fifth supralabial under the center of the eye, sixth just 

 touching the orbit anteriorly, and both separated from the orbital
