Slcin distinctly folded, the folds crossinf) each other and forming 

 scale-pouches. Teeth of old examjiles nniserial, without basal lobe ; in 

 younger examples the anterior mandibulary and maxillary teeth, and 

 also sometimes the vomerine teeth, are biserial. Mandible with from 

 ten to fourteen teeth on each side. Canines rather small ; the mouth 

 can be shut completely. The length of the anterior nasal tubes is 

 rather less than the vertical diameter of the eye. Snout compressed, 

 of moderate length. Eye of moderate size. Gill-opening as wide as 

 the eye. Tail a little longer than the body. The length of the head 

 is contained twice and one-third in that of the trunk. Gill-opening 

 without black spot. Brownish, marbled with darker ; on the back 

 the dark colour forms an incomplete network of wide meshes, and 

 the toil is crossed by dark cross bands. Young specimens without
