সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
পৃষ্ঠীয় কাঁটা (মোট ) : 0; পায়ূ কাঁটা : 0. Head profile rounded; snout short, blunt. Scales deciduous, with 1 to 3 divergent rows of small, thin spinules uniformly covering almost all of the body; scales absent over most of the snout and in wide patches on the head surrounding large pores of sensory lateralis system. Pyloric caeca rather long and slender, about 9 to 10. Overall color is dark brown to brownish black.
