counted only one. IMost of these differences are probably due to variation 

 exhibited by the several specimen* examined, while others are perhaps attributable 

 to errors arising from the difhcultv of accurately ol)ser\-ino- such small characters.

Body rather elongate, compressed ; jiartlv covered with non-imbricate, small 

 scales, which arc ap[)roximate posteriorly l)ut spaced anteriorly: lateral line rejire- 

 sented by minute raised tubules. Head naked, with large open pores on the 

 opercles, mandible, and suborbital regions : snout rounded, with large openings 

 and foliaceous lobes: no barbels: mouth slightly oblique, the jaws subequal : 

 maxilla ex])an(led, with an obtuse spine on its lower margin : a band of \illiforni 

 teeth on the premaxillaries, and some larger ones near the symphysis ; mandible 

 with a band of villiform teeth anteriorly, and an inner series of large spaced 

 teeth : an angular series of pointed teeth on the vomer, the exterior of which are 

 enlarged ; a triangular patch of pointed teeth on each palatine : tongue pointed, 

 free at the tip: gill-openings broad, lateral, the membranes united with the 

 isthmus ; seven branchiostegals : no pseudobranchiae ; gill-rakers reduced to 

 miiuite spinous tubercles: eyes small: opercles covered by a continuous skin, the 

 o]K'rculum with a strong spine, which pierces the membrane. Dorsal and anal 

 fins with branched rays, and distinct from the caudal; pectoral well developed: 

 ventrals close together behind the isthmus, each with a single ray. X'iviparous. 



Ogilby mentioned a spinous tubercle in front of the dorsal fin. regarding 

 it as an anterior dorsal : dissection proves this to be merely the end of a neural 

 spine, pressing against the skin owing to the shrivelled condition of the specimen. 

 The isthmus is also described as wide, whereas it is narrow.
