The general form of the body is cylindrical, the anterior half slightly 

 compressed, the posterior more so and tapering ; the head is elongated 

 conical, terminating in a narrow rounded muzzle near which in the 

 upper jaw appears a wide notch, which receives the long conical' teeth 

 near the symphysis of the lower jaw. The length of the head, mea- 

 sured to the gill-opening, is £ of the body, not including the caudal, 

 which latter varies from i to \ of the length of the head, The dis- 

 tance from the muzzle to the anterior margin of the orbit varies from 

 3^ times in to J of the length of the head. The distance across the notch 

 of the upper jaw is \ of the horizontal diameter of the orbit ; between 

 the anterior margins of the orbit it is £ , between the posterior margins, 

 it equals the horizontal diameter of the orbit. The latter is ^, or a little 

 less than \ of the distance from the muzzle to the anterior margin of the 

 orbit.* The latter margin is situated in front of the centre of the dis- 

 tance between the muzzle and the angle of the mouth, which distance 

 is a little less than \ of the length of the head to the gill-opening. 

 The anterior aperture of the nostrils is oval, provided with a short, yet 

 very distinct tube ; it is situated immediately above the lip, at the 

 termination of the notch, a little in front of the centre between the 

 muzzle and the anterior margin of the orbit. The posterior aperture 

 is linear, or more elongated oval than the anterior, with the margin 

 slightly raised, but not tubular ; it opens a little in front of the eye at 

 a distance from the anterior aperture equal to that of the latter from 

 the muzzle. On each side of the crown of the head, a little farther 



* In the larger, upper figure of the head in Calc. Journ. of Nat. Hist. V. PI. 

 VIII. Fig. 4, the eye is represented too small, and is placed too far back ; in the 

 smaller figure the eye is correctly placed, but the gill-opening is much too near the 

 angle of the mouth. These disproportions materially affect the position of the 

 dorsal and pectoral fins in the figure.
