1. Microscalabotes cowani. (Plate XIII. fig. 2.) 

 Microscalabotes cowanii, Bouleng. I. c. 



Head small, much longer than broad, not distinct from neck ; 

 snout obtuse, as long as the distance between the eye and the ear- 

 opening, not quite once and a half the diameter of the orbit ; ear- 

 opening very small, roundish. Body rather elongate, moderately 

 depressed, not distinct from the tail, which is almost as thick at the 

 base ; the latter tapers into a point, and is slightly depressed, 

 suboval in section. Limbs rather feeble ; digits gradually increasing 

 in size from first to fourth ; fifth half the length of latter ; seven 

 transverse lamellae under the dilated part of the third and fourth 

 digits, the two basal undivided ; the slender part of the digits with 

 narrow transverse lamellae. Upper surfaces covered with uniform 

 small granular scales, considerably larger on the snout and inter- 

 orbital space. Rostral broad, subpentagonal ; nostril pierced between 

 the rostral, the first upper labial, and two nasals, the upper being 

 the largest and separated from its fellow on the other side by two 

 granules ; six or seven upper and as many lower labials ; mental 

 rather larger, subtriangular ; irregular small chin-shields gradually 

 passing into the gular scales ; latter relatively large, though 

 considerably smaller than the ventrals, which are large, smooth, and 

 distinctly imbricate. Six or eight prseanal pores, forming a short 

 angular series. Caudal scales uniform, cycloid, imbricate, largest 

 on the lower surface. Reddish golden brown above, with darker, 

 greyish-brown vertebral and lateral bands ; tail with more or less 

 distinct darker angular markings ; labials brown-dotted ; lower 

 surfaces whitish, the throat with a few scattered brown dots.
