Indian Earth Snake

The following description of U. pulneyensis is from Beddome (1864: 180):

rostral rather obtuse, produced back between the nasals, and touching the frontals [=prefrontals], nasals not meeting; eye small, in [the] front of the ocular shield; no supraorbitals; vertical [=frontal] 6-sided; occipitals [=parietals] rounded behind; 4 upper labials. Scales round the neck 19, round the body 17; subcaudals, male, about 12, female 6–8. Tail [laterally] compressed, ending in a small spinose keel, more or less bicuspid. Scales of the tail all smooth. Colour uniform earthy brown; a lateral bright yellow streak from the labials continued on each side of the trunk, about 1 or 1½ inch in length; a few minute yellow specks on the back; belly with broad bright yellow transverse bands, very irregular as to number and shape; yellow markings about the vent and tail. Beddome (1864: 180) continues: "[pulneyensis and wynandensis] ... differ from the typical form of this genus in their much smaller size and in the absence of a supraorbital shield. As, however, they have the same [laterally] compressed tail, I prefer keeping them in this genus to making a new genus for them." Boulenger (1893) adds the following details: Adults may attain a total length of 38 cm (15 inches). Portion of the rostral visible from above longer than its distance from the frontal. Frontal longer than broad. …
