DUTCH BORNEO-EXPEDITION.

middle of the back between the longitudinal series of the 

 scales; only three of these stripes on the sacral region 

 and the beginning of the tail, the anterior and posterior 

 part of the scales also of a blackish colour, the central 

 quadrate putty grey, lower parts uniform grey, the upper 

 parts of the median portion of the tail with dark transverse 

 bands separated by lighter interspaces. 



Though the frontal of our specimen is evidently smaller 

 than the frontoparietals and interparietal together, and the 

 patietals form a suture behind the interparietal, I do not 

 think it improbable that this specimen belongs to Lygosoma 

 Vyneri, described by R. Shelford in Ann. Mag. Nat. Hist. 

 (7) Vol. 15, p. 208. 



Length from the tip of the snout to the vent: 63 mm. 



Length of the tail: 78mm. 



33. Lygosoma Hallieri, nov. spec. 



Section Homolepida. Body rather elongate, limbs short, 

 the distance between the end of the snout and the fore limb 

 is contained about once and a half in the distance between 

 axilla and groin. Snout short, obtuse. Lower eye-lid scaly. 

 Nostril pierced in a single nasal. No supranasals ; fronto- 

 nasal broader than long, forming a broad suture with the 

 rostral ; praefrontals forming a median suture ; frontal as 

 long as the frontoparietals and the interparietal together, 

 in contact with the two anterior supraoculars; four supra- 

 oculars; nine supraciliaries ; frontoparietals and interparietal 

 distinct, latter shield lozengeshaped, much smaller than the 

 frontoparietals ; parietals small, forming a suture behind the 

 interparietal, not in contact with the supraoculars from 

 which they are separated by the frontoparietal and another 

 smaller shield next to it. No enlarged nuchals; third to 

 fifth upperlabials below the centre of the eye, from which 

 they are separated by a series of scales. Ear-opening round- 

 ish, rather large, smaller than the eye-opening. 40 smooth 

 scales round the middle of the body, ventrals largest. 

 Praeanals not enlarged. The length of the hind limb 

 equals the distance between the anterior corner of the eye
