Obsert. — The unique specimen of this species which we have had 

 an opportunity of examining, measures an inch and a half, the tail not 

 inchided : it is therefore immature. The adult has been well illus- 

 trated by Schlegel. 



The rostral plate is small and subpyramidal ; immediately behind it, 

 is a pair of subquadrangular internasals, contiguous upon their medial 

 line, and extending also in advance of the nostrils, so as to officiate as 

 prenasals, preventing the nostrils from approaching the rostral. A 

 quite small pair of flattened supero-nasals may be observed, separated 

 on the middle line of the rostrum, though contiguous to the anterior 

 pair. A small, odd plate may also be observed at the commissure of 

 the large internasals. There are ten upper labials on either side, quad- 

 rangular, longer than deep, and diminishing gradually posteriorly. 

 The symphyseal is small and subtriangular, inclosed posteriorly by a 

 pair of subtrapezoid, mental shields. Small, slender, elongated plates 

 may be seen lining the lower labials, which are ten or eleven on each 

 side, diminishing backwards ; the five anterior considerably larger 

 than the rest. 



With the above few remarks we must dismiss this species, regret- 

 ting that we had no adult specimen to enable us giving an elabo- 

 rate description of it.
