“Typhlops nigrescens, Gray, Oat. of Lizards in Col. Brit. Mus., p. 185. 
Dr. J. E. Gray gives the following description of this species: —“‘ Body 
slender, blackish ; chin and under side white, the line of separation rather 
ragged ; the dorsal scales pale edged, especially on the front ; head whitish 
in front, the head shields more or less clouded with grey in the centre; 
the rostral moderate, rounded above, rather curved on the sides; central 
crown-shields rhombic, as long as broad, the first the largest, the second 
and third of equal sizes; tail short, and tapering, rather longer than wide, 
tip rather blunt, scarcely incurved.”’ The typical specimen in the British 
Museum collection was found at Parramatta ; another example in Vienna 
was obtained by the naturalists of the “Novara,” probably from the neigh- 
bourhood of Sydney. The last specimen measures 83 inches 5 lines, the 
tail being one inch long. The figures are considerably enlarged.
