its distance from the end of the tail is contained very 

 nearly three times in the body's length. 



Scattered pigmentary spots are met with on the 

 head, also along the base of the caudal fin, but few 

 in number here, and- small. 



There is one specimen in the collection, obtained 

 in 1885 by Captain von Scheele in the Indian Ocean 

 off the East Coast of South Africa (Lat. 29° 20' S. 

 Long. 38" 40' E.). The dimensions are as follows: 



Length of body 36 mm. 



Greatest height of body 4,5 „ 



Distance from extremity of snout to vent 23 „ 



Length of head 3 „ 



Distance from extremity of snout to eye's 



anterior margin* 1 „ 



Eye's diameter 0,5 „

PI. IV. f. 3 and 4. 



The body is strongly compressed, short and high ; 

 its greatest height, contained rather more than six 

 times in its length, is situated at a point a little in 

 front of the middle ; thence the height diminishes gra-

 sibly rather more rapidly towards the latter. 



The head is small; its length is a trifle greater 

 than half the body's height. Its upper profile is con-

 of the eye it has a concavity, afterwards it is straight
