Might side. The length of the head is ^ of the total. The upper 

 orbit is placed horizontally on the upper surface of the head ; its dis- 

 tance from the muzzle is § of its longitudinal diameter, which is J of 

 the length of the head. A little below, and in front of the upper orbit, 

 on the left side of the muzzle, appears the posterior circular aperture 

 of the left nostril ; the anterior one is smaller, tubular and situated a 

 little in front of the posterior. The right orbit is slightly shorter than 

 the left, and is situated vertically on the left side of the head, bordering 

 upon the upper maxillary. The circular pupils are protected by a 

 number of vermicular silvery filaments which diverge from the upper 

 margin of the iris. The distance between both orbits scarcely exceeds 

 ^ of their diameter ; each orbital margin is a little raised with a narrow 

 intervening furrow. The apertures of the right nostril are situated 

 immediately in front of the right eye, and resemble the corresponding 

 of the left. The upper maxillary is elongated, widened and truncated
