sides of the trees at some distance from the ground and they 
immediately took refuge much higher up the tree; thus many 
specimens escaped. Only three specimens, brought down with 
the vines, were captured. 
This species differs markedly from the two small species 
Siaphos infralineolatum Peters and Siaphos quadi'ivitatum Peters 
in size, markings, and the presence of an auricular opening. 
From the recently described Siaphos auriculatum Taylor, which 
it resembles greatly in markings, it differs in the presence of 
small prefrontals, and it probably does not grow so large. Many 
other differences are obvious on a comparison of descriptions 
and figures. Known only from the type locality. 
Sphenomorphus lednickyi sp. nov. Fig. 4. 
Type. — No. R 1992, E. H. Taylor collection; collected in June, 
1917, on Masbate Island, by Victor E. Lednicky. 
Description of type. — Rostral only 
slightly visible from above, forming a 
broad, rather curved suture with fronto- 
nasal; latter much broader than deep, 
broader behind than in front, in contact 
with anterior frenal; prefrontals large, 
broadly in contact, touching both frenals 
laterally, not in contact with first supra- 
ocular; frontal as wide as, or slightly less 
than, the supraocular region, in contact 
with first superciliary and two supra- 
oculars, narrowed behind; frontoparietals 
distinct, rather elongate, broadly in con- 
tact ; interparietal much longer than wide, 
with a distinct eyespot; parietals forming 
a suture behind interparietals ; no nuchals 
present ; five supraoculars, last very small, 
first deepest, second widest; nostril 
pierced in a single nasal ; no supranasals ; 
anterior frenal not as high as nasal, much higher than wide; 
second frenal wider at top than bottom, lower than anterior; 
three preoculars superimposed, between first superciliary and 
third labial; six upper labials, fourth and fifth under eye, but 
separated from orbit by several scales ; third labial smaller than 
second ; five lower labials ; mental small, followed by a very wide 
postmental ; three pairs of chin shields, only first pair in contact ; 
four enlarged temporals, that bordering parietal largest; auri- 
cular opening very large; tympanum very superficial; 40 rows
