Description

Description after 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."

After Beddome (1864: 180), 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. Diameter of the eye ½ the length of the ocular shield. Diameter of the body 30 to 38 times in the total length. Ventrals about twice as large as the contiguous scales, 161-180. Tail somewhat laterally compressed. Usually some of the terminal dorsal scales of the tail with faint keels.[3]

Geographic range

It is found in Southern Western Ghats in Tamil Nadu and Kerala states of South India (Palni, High Wavy Mountains and Travancore hills, 5,000-7,000 feet).

• Type locality of Plectrurus pulneyensis: "Pulneys at an elevation of 7,000 to 8,000 feet".
• Type locality of Silybura guentheri: "High Wavy mountain, Madurai district, 5000 feet elevation".[2]
