 From the Liverpool Museum. 



The Liverpool Museum possesses an example of this form. 

 250 millims long. It is not in the least more developed than 

 examples of half this length. 



There is another very interesting example in the collection of the 

 same museum, 90 millims. long, obtained in the South Atlantic by 

 Capt. Whiteway. Its head is ossified ; but the notochord is a simple 

 soft thread. The muscles are of considerable consistency, and adhere 

 to those of the other side. The black spots along the lateral and 

 abdominal lines are as large as the eye, and distinct from each 

 other. 



4. Body narrow and excccdinyhj elonyate ; tail taperiny into ajilament. 



Body 270 millims. long and 6 millims. deep. Head small. Snout 

 acutely pointed, at least twice as long as the eye ; both jaws toothed. 

 Gill-membranes united across tlie isthmus. Tongue not free in 

 front. Pectoral fins none ; vertical fins very indistinct. Chorda 

 dorsalis without any ossifications. Intestine extending into the 

 narrow portion of the posterior part of the body. 



One cxamjilc is in the Liverpool Museum. It is not known where 

 it was obtained.
