One specimen differs from the type in having only eight upper labials, the fourth 

 and fifth entering the orbit. The dentition appears to be, upper jaw 16 + 16=32 ; 

 lower jaw 16 + 16=32. Length 45 inches ; head 0-95; tail 9-25. Ventrals 236; 

 sub-caudals 99 ; scales in 19 rows. 



In another specimen of this variety, with eight upper labials, the third, fourth 

 and fifth enter the orbit, and both anterior temporals are in contact with the post- 

 oculars. 



These specimens, however, agree in every other respect with C. radiatum. They 

 were obtained at Mandalay.
