26 NILS GYLDENSTOLPE, THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 1. SXAKES. 



Seems to be fairly common in Siarn even up in the north on suitable localities. 

 However, it is most often met with in sugarcane plantations. 

 It is much dreaded by the natives. 



41. Callophis maculiceps Gthr. 



One specimen, Doi Sutep, near Chieng Mai, Northern Siarn '1300 in.), May 1914. 



This small snake has only quite recently been recorded from Siarn, but as it 

 inhabits both Burma and Cochin China it is probably much more common than as 

 appears from the few records of its occurrence in Siarn. 



The colour of the specimen obtained does not quite agree with the description 

 given by Boulenger in his Catalogue Brit. Mus. nor with the colour variety de- 

 scribed by Dr. Smith (Journ. Nat. Hist. Soc. of Siarn, Vol. I, N:o 2, p. 125) and my 

 specimen probably forms a new colour variety. 



Colour: Head blackish with some påle yellow on the scales; on the upper lip 

 there is a påle j r ellowish line; nape black forming a collar; upper parts of the 

 body påle brownish with the usual small black döts in alternating series of two 

 larger ones near the costal line and two smaller ones near the vertebral line which 

 is of a darker brown than the upper parts of the body; tail with two rather broad 

 black bands and a few black döts between these bands; tail below almost black 

 with a few light coloured scales. 



Total length — 335 mm. 



Length of tail = 30 » 



Ventrals- 198.

5 lower labials are in contact with the anterior chin-shields. 



42. Amblycephalus moellendorffi Boettqr.

\.b Par as I know only one specimen has been found in Siarn before (collected 

 by Mm hot iii the mountains of Laos). 



It also inhabits Tenasserim, Coohin China and Soutern china.
