 The tongue in life is blackish with whitish tips. The secretion from the

 a similar limpid secretion in some other vipers. 



In the annexed table of details it will be seen that the scale rows are 

 noi'mally 21 anteriorly, and 17 behind. 



In 4 specimens the scale rows anteriorly were 19 in places, and in all the 

 4th and 5th rows above the ventrals had fused to reduce the normal number. 

 The resulting scale divided, and the parts again fused, sometimes ." or 4 

 times before the normal 21 rows were finally established.
