the specimens are bluish green, anteriorly with many irregular 

 dark spots mixed with small black spots and many smaller flecks ; 

 posteriorly the ground color is olive green to brown, the spots 

 rather disappearing or uniting to form larger more regular 

 spots ; tail greenish. 



The specimens from Bongao are olive to brownish green above 

 with large black spots on the back of the head and many quad- 

 rangular black spots on the back with similar greenish white 

 spots ; tail olive gray with annulations dimly marked with whitish 

 spots. Neither of these forms can be placed with the color 

 varieties described and admirably figured by Barbour.^ 



Tropidophorus rivularis Taylor. 



A number of specimens were taken near Zamboanga. They 

 agree with the type, except that the interparietal is not divided.® 

 I did not find this species in Sulu Archipelago. It is highly 

 probable that this or a related species does occur on those islands 

 that have running water. Species of this genus are constantly 

 found along small fresh-water streams, usually under partly 

 submerged rocks or logs.

Description of type. — Snout blunt, rather flattened; rostral 

 bent back over end of snout, forming a moderate suture with 

 the frontonasal; the latter longer than broad; prefrontals nar- 

 rowly in contact, wider than deep, touching both frenals, first 

 superciliary, and first supra-ocular; frontal large, a little longer 

 than broad, in contact with two supra-oculars, narrowly in con- 

 tact with the interparietal; the latter little longer than wide, 

 much larger than the frontoparietals; parietals elongate, nar- 

 rowly in contact behind the interparietal; no nuchals; nostril 

 pierced in a minute nasal, followed by a small postnasal; an- 

 terior f renal nearly twice as large as the second; a small pre- 

 ocular between the first superciliary and the third labial; five 

 supra-oculars, second largest and widest; five or six supercilia- 

 ries; six upper labials, first largest, fourth below eye; two 

 small scales above the fifth labial; mental deeper than post- 

 mental, but not as wide; three pairs of chin-shields, the first

 * Probably anomalous in the type. 



" There are two islands in Sulu Archipelago by this name, one is in the 

 Tapiantana Group, the second lies to the south in the Tapian Group.
