Description. — The head of this singular fish is produced into along 

 compressed tube, terminating in a mouth which is comparatively 

 small. The length of the head is somewhat less than one -third of 

 the total. The cleft of the mouth is slightly oblique when closed, 

 with the extremity of the lower jaw somewhat prominent and com- 

 pressed into a sort of keel. A small barbel hangs down from the 

 symphysis. The intermaxillary is feeble, styliform, not protractUe, 

 whilst the maxillaiy is broad, lamelliform, and triangular. The 

 upper jaw is united to the lower by a broad membrane, which renders 

 the cleft of the mouth much narrower than one woidd expect from 

 the extent of the jaw-bones. 



Although Cuvier and the following authors have denied the pre- 

 sence of teeth, patches of minute ones are distinctly visible ; they 

 become more conspicuous if the head is allowed to dry. The inter- 

 maxillary is perfectly toothless ; the mandible has a short and narrow 

 band on the edge near the symphysis, and a broad rough patch on its 

 inner surface ; there is a similar patch on the palatine bones, whilst 

 the vomer is provided with a long, very narrow band of mi nute teeth. 

 The inner concave part of the branchial arches and the upper and 

 lower pharjTigeal bones have patches of villiform teeth. 



The diameter of the eye is one-half or two-fifths of the extent of 

 the part of the head behind it ; the space between the orbits is flat 

 or a little concave, with a shght ridge on each side, both converging 

 anteziorly and soon meeting in a point. The eye does not appear to 

 be comparatively smaller in adult specimens than in young ones, as 

 is the case in most Teleostei. The nostrils are close together, one 

 before the other, in front of the orbit and on the side of the head. 

 The operculum is subquadi'angular, longer than high ; the suboper- 

 culum occupies a triangiUar space between the operculum and pra3- 

 operculum, and is carried backwards along the inferior margin of the
