14 J. Anderson — Reptilian Accession to the Indian Museum. [No. 1, 



Sab. Cachar. 



This form is closely allied to E. monticola from which it is distin- 

 guished by the greater number of the keels on its scales and by 

 the length of its tail. It is in all probability a hill form. 



Gecko ttdje. 



Hernidactylus Bengaliensis, n. sp. 



Body uniformly granular. An enlarged white tubercle on the 

 side of the neck before the shoulder. No enlarged tubercles on 

 the sacral region. Tail flattened from above downwards, flat on 

 the under surface, contracted at the base and then expanded into 

 broad verticils. A prominent almost spiny tubercle directed 

 backwards on the posterior inferior margin of each verticil, with 

 or without a small tubercle above it on the dorsal and lateral margin. 

 The perfect tail a little longer than the body. Eight or nine 

 femoral pores, not continued on to the preanal region. Thirty-five 

 longitudinal series of scales on the middle of the abdomen. The 

 rostral with a longitudinal groove on its upper surface. A pair 

 of moderately-sized rounded plates behind the rostral, separated 

 from each other by two granules, placed longitudinally and forming 

 the upper margin of the nostrils. Two small plates enter into the 

 posterior margin of the nostril, the first labial defining it below. 

 Fifteen upper labials, the hinder ones very small. Eleven lower 

 labials. Two large shields behind, broadly in contact with each 

 other, and forming a suture with the sides of the mental and with 

 the first labial. A pair of small shields on the external side of the 

 post mentals. Two irregular lines of small shields of variable size 

 below the lower labials. Twelve transverse imbricate plates in 

 double series on all the fingers, except the thumb which has only 

 10, the distal on all, and sometimes the proximal, being undivided. 

 Fingers all clawed, the claw of the thumb being very small. The 

 upper surface of each finger is covered with about 5 longitudinal 

 lines of enlarged almost scaly granules, the interval between them 

 and the disks being occupied by minute granules. Thirteen im- 

 bricate plates in double series on the second and third toes, the 

 distal and proximal ones being undivided ; twelve on the 4th 

 and 5th toes, the proximal ones being single or partially divided,
