The body is compressed, exceedingly elongated and 

 rather low; for the greater part of its length it is al- 

 most uniform in height; its height, where it reaches 

 a maximum, would go nearly twenty-four times into 

 the length, towards the head the decrease is inconsi- 

 derable, but in the, other direction it is so great that 

 the end of the body is almost threadlike. 



The head is small; its length is contained about 

 once and two thirds in the greatest height of the body. 

 Its upper profile is very convex in the hinder part, 

 but just in front of the eye it makes a distinct con- 

 cavity. This causes the slightly arched snout to ap- 

 pear in contrast depressed. The snout is pointed. The 

 distance between the extremity of the snout and the 

 anterior margin of the eye is about twice as large as 

 the diameter of the eye. The eye has a circular con- 

 tour; its upper margin does not reach up to the upper 

 profile of the head. The posterior nostril is situated 

 immediately above the anterior margin of the eye; 

 the anterior nostril, in the shape of a short tube obli- 

 quely truncated, is situated a little in front of the 

 posterior but rather lower. The cleft of the mouth
