The body, is compressed, short and high ; its grea- 

 test height, contained about five times in its length, 

 is in front of the middle; from that point the height 

 decreases fairly rapidly towards the head, more slowly 

 towards the tail. 



The head is rather small and considerably depres- 

 sed from the trunk ; its length is contained about once 

 and three fourths in the body's greatest height. Its 

 upper profile is slightly convex, but has an inconsi- 

 derable depression just in front of the eye. The snout 

 is blunt. From its extremity to the anterior margin 

 of the eye the distance is nearly double the latter's 

 horizontal diameter. The lower part of the eye is 

 somewhat contracted, the vertical diameter tends 

 somewhat obliquely frontwards; its upper margin does 

 not reach to tbe head's upper profile. The posterior 

 nostril is situated at a short distance from the eye's 

 anterior margin about on a level with its middle 

 point ; the 'anterior nostril is as far from the posterior 

 as from the extremity of the snout,
