174 OPHIDIA. 



Ttphlops bothriobhynchus. (Plate XVI. fig. G.) 



Nostril lateral. A round groove, larger than the nostril, on the suture between nasal and 

 fronto-nasal, below the nostril ; another similar but smaller groove on the suture between 

 rostral and nasal. The upper part of the rostral one-third of the width of the head, the 

 lower much longer than broad. Nasal very broad below, as broad as the fronto-nasal in the 

 middle ; the suture between both these shields is continued above the nostril. The fronto- 

 nasal extends a little backwards to the hinder side of the rostral ; its posterior margin is 

 deeply concave. Prseocular and ocular subequal in size. Four labials : the first in contact 

 with rostral and nasal ; the second with nasal, fronto-nasal, and preeocular ; the third slightly 

 ascending between prseocular and ocular ; the fourth not much larger than the third, scarcely 

 reaching further backwards than the ocular. All the shields on the crown of the head are 

 enlarged, the supraoculars and the interparietal being rather the largest, the latter being 

 very broad, though short. 



Body not much thicker behind than in front ; the circumfei'ence in its middle is one-twelfth 

 of the total length. Tail curved, its length being equal to the width of the head ; it termi- 

 nates in a minute spine. The body is surrounded by twenty-four longitudinal series of scales. 

 I count 329 transverse series ; ten series round the tail. 



Uniform brownish olive above and below. 



I have examined a single specimen from Pinang (Dr. Cantor's collection) ; it is 7 inches long. 

 The views of the head are of thrice its natural size. 



Typhlops striolatus. 



Typhlops striolatus, Peters, Monatsber. Berl. Acad. 1801, p. 922. 



The upper portion of the rostral shield band-shaped, extending backwards to between the 

 eyes, broader than the lower part. The nasal is partly united with the fronto-nasal above 

 the nostril, and touches the fu'st and second labials. Fronto-nasals not contiguous behind 

 the rostral, with their lower portion as long as the corresponding part of the nasal ; their 

 hind margin is concave. The second labial in contact with nasal, fronto-nasal, and proeocular ; 

 the third labial has an acute upper angle wedged in between prseocular and ocular. Prse- 

 ocular as large as ocular ; eye very distinct. Supraorbitals and parietals broader than the 

 frontals, which are of the same size ; interparietal nearly twice as broad as frontal. 



Body rather thicker behind, surrounded by twenty-four series of scales. Tail shorter than 

 the head, curved, terminating in a minute spine, with eight transverse series of scales. 



Olive-brown above, the darker terminal part of each scale separated from the lighter base 

 by a yellow, posteriorly black-edged, transverse streak ; paler below. 



The typical specimen, a female, 12\ inches long, came from the banks of the Ganges.
