174 LIZARDS OF THE PHILIPPINE ISLANDS 



borders parietal and is surrounded by three large and two smaller 

 temporals ; seven upper labials, sixth and seventh largest, below 

 eye; mental large, followed by a single azygos postmental; this 

 followed by two pairs of chin shields bordering the labials, 

 first in contact, second pair separated by a single scale; thirty- 

 six scale rows around body, laterals somewhat smaller than 

 dorsals or ventrals; two enlarged preanals; the median row of 

 scales under tail slightly widened; ear opening very much 

 smaller than eye; tympanum rather deeply sunk; eye nearly 

 equal to its distance from nostril ; distance of eye to ear greater 

 than distance of eye to nostril; lower eyelid scaly; adpressed 

 hind leg just fails to reach elbow of adpressed foreleg; twenty- 

 two lamellse under fourth toe. 



Color in life. — Above rather reddish brown with a series of 

 dim, irregular, slightly darker bands separated by very narrow, 

 irregular, broken, lighter lines across back but darker on sides, 

 where they appear as large blackish spots (especially on neck 

 and shoulder), more indistinct along sides; many small black 

 spots scattered along back and on tail ; head lighter brown with 

 yellow spots on labials; a distinct dark spot between eye and 

 ear; tail with narrow, broken, lighter, transverse bands, rather 

 indistinct, about thirty-seven in number; throat and chin with 

 a few darker markings ; belly immaculate dull white ; arms and 

 legs above mottled and finely streaked with darker; tail below 

 dull purplish pink.

Variation. — Specimens from Mindanao vary but little among 

 themselves. All have thirty-six scale rows, a single specimen 

 excepted, which has thirty-four. The lamellse under fourth toe 

 are either twenty-two or twenty-three. The frontoparietal 

 is constantly single. By this character the species is readily dis- 

 tinguished from S. jagorii that occurs in the same locality. 

 However, in the Mindoro specimens of S. jagorii the frontopa- 

 rietal is normally single. This form has been given subspecific 

 rank. The differences in size and markings, however, distin- 

 guish S. coxi from the various subspecies of S. jagorii.
