Liasis petersii. n. sp

In the August number of the »Monatsberichte der Akademie der Wissenschaften zu Berlin”, for 1876, p. 533, Prof. Peters notices a specimen of what he calls: Liasis amethystinus, var. timoriensis, which was brought from Timor by the German man-of-war» Gazelle” on her cruise in the Indian and Australian seas. On the accompany ing plate he gives figures of the head and anal region of this species, together with corresponding drawings taken from a true Liasis amethystinus. Tlie above mentioned figures look different in many respects and I was surprised to find in our museum a snake, hitherto undescribed, which corresponds, as far as the configuration of the scales on its head goes, with Prof. Peters’ socalled Timorese variety of Liasis amethystinus.
