HT. pallidiceps is allied to H. variegatus and stephensii, and has a 
broad head and keeled ventrals; it is one of the smaller species, which 
seldom exceed thirty inches in length, and whose bite would not be 
dangerous to man. This snake is rather rare, and does not occur near 
Sydney. The Australian Museum contains specimens from the Lachlan, 
the Clarence, and the Richmond River, and from many parts of Queens- 
land. The most northern specimens were obtained at Port Denison.
