ON NEW REPTILES FROM BKITISH NEW GUINEA. [Juiie 16, 



Lygosoma pratti. (Plate XIII. fig. 1.) 



Section Lygosoma. Body elongate, limbs short ; the distance 

 between the end of the snout and the fore limb is contained once 

 and three fourths in the distance between axilla and groin. Head 

 small, much depressed ; snout moderate, obtusely pointed. Lower 

 eyelid scaly. ISTostril pierced in a single nasal ; no supranasal ; 

 i-ostral narrowed and produced posteriorly between the nasals, 

 forming a narrow suture with the frontonasal, which is a little 

 brocxder than long and narrowly in contact with the frontal ; 

 latter as large as frontoparietals and intei'parietal together, much 

 broader than the supraocular region, in contact with the first 

 supraciliary, the first supraocular, and a very small part of the 

 second ; four supraoculars ; seven supraciliaries ; frontoparietals 

 and interparietal distinct, subequal ; parietals forming a suture 

 behind the interparietal ; no nuchals ; fouith and fifth labials 

 below the eye. Ear-opening oval, nearly as large as the eye- 

 openmg; no auricular lobules. 36 smooth scales round the middle 

 of the body ; dorsals, especially the two A-^ei'tebral seiies, largest. 

 A pair of slightly enlai'ged praeanals. Limbs widely separated 

 when pressed against the body. Digits short, compressed, keeled 

 below; subdigital lamellse mostly divided, 13 or 14 under the 

 fourth toe. Tail veiy thick. Pale brown above, mottled or 

 vermiculate with dark brow^l ; head and nape blackish ; two 

 oblique white streaks from below the eye to the throat ; belly 

 white.

This new species, of which a single specimen was obtained at 

 Dinawa, Owen Stanley Range, 4000 feet, by Mr. A. E. Pratt, is 

 most nearly related to the Papuan L. muelleri Schleg., and 

 clearly belongs to the same section of the genus Lygosoma. But 

 it is also closely allied to L. lorice Blgr., fi'om New Guinea, which 

 has been referred to the section Ilinulia and evidently constitutes 

 a connecting-link between the two sections. 



Having, through the kindness of Mr. Thomas Steel, of Sydney, 

 had the loan of the type of Homoleplda englishi De Vis, I am 

 able to confirm its identity with L. muelleri, as already pointed 

 out by me in the ' Zoological Record ' for 1890. 



TOXICOCALAMUS STANLEYANUS. (Plate XIII. fig. 3.) 



Rostral much broader than deep, just visible from above; inter- 

 nasals nearly as long as the prsefrontals, which are in contact with 

 the second upper labial and with the eye ; frontal small, slightly 

 broader than the supraocular, once and three fourths as long as 

 broad, as long as its distance from the end of the snout, a little 

 shorter than the parietals ; one postocular ; temporals 1 -f 2 ;
