Body veryoloiigatc, i(s liciglit nearly equal to its tliic,kiie,ss,un(l scarcely one seveiiti'L-iilli 

 of its len.sitli; lengtli of head oue-eii-litli length of the body. Uead Hattened, enveloped 

 iu mucous skin; snout rounded; its length one third that of the head. .Mouth small, lips 

 thick, fringed; the upper jaw fastened far beyond tlie lower one, though the thickness of 

 the integument does not allow us to deterniine tlu' i)oint where the maxillary terminates. 

 Teeth very nearly conical, jiointing backward, in both Jaws; teelh alsouimn the vomer and 

 palatines. A single nostril is distinguishable, tubular, and placed far forward on the 

 border of the lip, so that at lirst sight it might be mistaken for one of the mucous openings, 

 of which there are about six on the upper jaw, and four or five iu each branch of the lower 

 jaw. Eye superior, scarcely visible even in the fresh specimen, being hiilden under the 

 skill; diameter scarcely one-ninth of the length of the head and onelhird thatof the ninz/.le 

 ecpia'ling the width of the interorbital space. The branchial opening is very large, though 

 the branchiostegal membrane does not adhere to the isthmus but l)y a very slight attach- 

 ment. The skin of the head is naked. 



The vent is found a little in advance of a. point which is two-sevenths of the distance 

 from the tip of the snout to the tip of the tail. Scales, reseiubling ^)al(^ spots, are very .lis- 

 tiuct ou the posterior part of the body, and in the forward part of the body they may be 

 seen clearly ou the ventral portion of the animal after it has been kept m alci.lml. A lateral 

 line, scarcely distinguishable, is anterh.rly nearly iu the middle of the height, but poste- 

 riorly descends close to the ventral line. , , „ , „ ,, 



Dorsals placed far back, commeTieing at the end of the anterior fourth ol the length; the 

 origin of the anal still farther back. These flns are low, exactly similar, coalescing with 

 the caudal. Pectoral large, enveloped iu a thick integument; its extremity does not reach 

 to the-vertical from the origin of the d.nsal. The ventrals are represented «;^'-^ ^^ «^ 

 ray apparently, although it is probable that, in reality, there are several united ,n the same
