 Length 195 mm. Height 30 mm. Head 7 mm. Distance of 

 anus from end of tail 29 mm. Snout 2, eye 2, postorbital part

with 12 — 15 rays. Head pointed. The gape of the mouth reaches 

 behind the middle of the eye. The larval teeth have already 

 been lost. In their place very tiny teeth, mixed with a few 

 somewhat larger ones, can be seen in the jaws. Nostrils rather 

 close together before the eye, the posterior ones the larger.

The presence of pectorals, of sensory canals on the head, 

 the development of the olfactory pit and the loss of larval 

 teeth show that the specimen belongs to the last metamor- 

 phosing stage before becoming a glass-eel.
