SPHENOMORPHUS 183 



than high, much narrowed laterally in front of first labial 

 below nasal; frontonasal a little broader than deep, forming a 

 straight suture with rostral, laterally in contact with upper 

 anterior f renal, posteriorly in contact with frontal; prefrontals 

 rectangular, separated in the middle, in contact laterally with 

 upper anterior f renal, the posterior, and a single superciliary; 

 frontal much elongate, narrowed behind and in front; distance 

 between supraocular regions about one-third the width of 

 region above one eye; frontal little shorter than frontoparietal 

 and interparietal length, in contact with two supraoculars; 

 frontoparietals slender, pointed in front, forming a common 

 suture much more than half their length; interparietal nearly 

 as broad as frontal, but not nearly as long ; as large as a single 

 frontoparietal scale; parietals large, in contact behind inter- 

 parietals, touching last supraocular and two small postoculars; 

 no nuchals ; nasal quite large, the scale placed diagonally, touch- 

 ing only one labial; two anterior frenals superimposed, the two 

 not as high as nasal, but higher than the very large frenal follow- 

 ing, which is much wider at top than at bottom, touching two 

 labials; two preoculars, lower largest, followed by two moder- 

 ately large scales below eye, second partly wedged in between 

 fifth and sixth labials ; ten superciliaries ; five large supraoculars 

 followed by two paired scales, first supraocular more than a third 

 of the length of the supraocular region, second widest; nine 

 upper labials, sixth below orbit, sixth and seventh largest; five 

 distinctly enlarged temporals, the largest bordering parietal; 

 eight or nine lower labials ; one unpaired postmental ; two paired 

 chin shields, first pair in contact, second separated by one scale ; 

 anals enlarged; twenty-three lamellae under longest toe; ear 

 opening moderate, vertically oval; forty-two scale rows around 

 middle of body; adpressed hind leg reaches beyond elbow of ad- 

 pressed foreleg ; adpressed foreleg reaches anterior corner of eye. 

 Color in alcohol. — Above rich reddish brown traversed by 

 about thirteen indistinct bands of light, black-edged dots on back, 

 and continuing on tail; behind eye to above foreleg is a large, 

 broad, dark brown stripe, bordered below by a white stripe 

 which begins on second labial and continues back to ear, then 

 widens and takes a backward and downward course to front 

 limb; below this there is a rather irregular mottled area of 

 brown ; lower labial fiecked with brown ; limbs above mottled 

 with elongate light spots; sides somewhat lighter, flecked with 

 brown ; a brown area above hind limb ; below yellowish. There 

 is a very dim row of brown spots along upper lateral region.
