5. Calamaria vermiformis D. & B., var. sumatranus mihi. 



Two specimens of Calamaria in the collection of Dr. 

 Hagen agree as to the pholidosis in all points with the 

 description of Calamaria vermiformis given by Dumeril 

 and Bibron , but differ from it as to the coloration. 



Both specimens have 5 upper-labials , the first pair of the 

 lower ones do not form a suture but touch the chin-shield, 

 whilst an azygos shield lies between the four chin-shields. 



There is one foursided praeocular, the upper side of 

 which has twice the length of the lower one. The scales 

 are arranged in 13 rows; one specimen has ITOventrals, 

 one undivided anal and 19 pairs of caudals , the other 

 has 165 ventrals , one undivided anal and 22 pairs of 

 caudals. 



As to the coloration both specimens differ from Cala- 

 maria vermiformis in having the upper parts brown with 

 a bluish shine from the lips till the end of the tail , with- 

 out any yellowish band or any spots. The four anterior 

 upper-labials are brown also , only the h^^ having a yel- 

 lowish colour.
