]aro-e : ear completelj^ hidclon. 22 smooth scales round the middle 

 of the bod}', dorsals a little larger than laterals and ventrals. A pair 

 of enlarged praeanals. Tail thick, l^ale grej'ish brown, with a pair 

 of dark brown streaks along the middle of the back and a broader 

 dorso-lateral jiair; below the latter and on the bell}', brown lines 

 run between the series of scales. 



Total length 95 mm. : tail ( reproduced ) 35 mm. 



The single specimen described was found beneath a log at 

 Bangtnphan. 



This species is very closeh' related to the Australian L. opliio- 

 scincAis, Blgr. (Oji/iioscincus au^lralis, Peters), which differs in the 

 rostral forming a broader suture with the fron'onasal and in the 

 broader frontal and parietals. 



SiMOTES INORNATUS. 



Nasal divided ; portion of rostral seen from above, as long as 

 its distance from the frontal ; suture between the internasals longer 

 than that between the praefrontals ; frontal as long as its distance from 

 the end of the snout, as long as the parietals ; loreal a little longer 

 than deep ; one praeocular and two postoculars ; no suboculars ; 

 temporals 1 + 2 ; eight upper labials, fourth and fifth entering the eye ; 

 four lower labials in contact with the anterior chin-shitdds, which are 

 nearly twice as long as the posterior. Scales in 15 rows. Ventrals 

 171; and entire; subcaudals 42. Uniform pale brown above, jellowish 

 white beneath. 



Total length 580 mm.; tail 90 mm. 



A single male specimen from Nong Kai PJoi, E. of Sriracha. 



The number of rows of scales easily distinguishes this species 

 from 8. violaceus, Cantor, to which it is most nearly related. 



[This snake was collected and kindly forwai'ded to me by Mr. 

 P. A. R. Barron, of the Borneo Company, to whom 1 am also indebted 

 fur a second specimen, which differs from the type description in the 

 following particulars. Portion of rostral seen from above, shorter than 

 its distance from the frontal : suture between the internasals equal to 

 to suture between the praefrontals. Loreal as long as deep. Ventrals 

 175. Subcaudals 40. Color. Above, dull, salmon-red ( nnich brighter, 

 1 am informed, in life ) and with ver}- faintl}^ marked dark gi'eyish 

 narrow cross-bars. Below, with indistinct, small, squarish spots, placed 

 laterally, in the posterior half of the body and tail. This specimen has 

 been in my possession for some months, and the handsome red coloring 

 has oraduallv faded until now it is nearlv of the brown hue described
