(9) _A. micropholis._--Temporal shields small, 2 + 3 or 4; fourth or fifth infralabial larger; scales on the body in 25 rows; 210-215 ventrals; 29-30 subcaudals.

(10) _A. leucomelas._--Characters as before. Frontal one and two-fifths as long as broad, as long as the parietals. Colour black, with a vertebral white line, occupying one row and two half rows of scales; ventrals and subcaudals white; neck black, head white, with a black spot covering the nasals and upper head-shields.

Colour uniform dark brown. Total length, 540 millimetres; tail 45. _Habitat_: Central and East Africa. _D.--AUSTRALIA AND THE LARGE ADJACENT ISLANDS._ The Sunda Islands and the whole of Malaysia are rich in poisonous snakes. Those that are found there belong for the most part to species that we have already met with in India or the Malay Peninsula. We shall therefore not describe them again here. All those that inhabit Australia are included in the great Family COLUBRIDÆ and the Subfamily _Elapinæ_. There are no VIPERIDÆ; but certain genera of poisonous COLUBRIDÆ are peculiar to this continent. These reptiles have been particularly well studied by Gérard Krefft, formerly Director of the Australian Museum at Sydney, from whose work[5] we shall borrow a considerable portion of the following notes, and the figures accompanying them. The genera represented in Australia are:-- (a) _Ogmodon._ (b) _Glyphodon._ (c) _Pseudelaps._ (d) _Diemenia._ (e) _Pseudechis._ (f) _Denisonia._ (g) _Micropechis._ (h) _Hoplocephalus._ (i) _Tropidechis._ (j) _Notechis._ (k) _Rhinhoplocephalus._ (l) _Brachyaspis._ (m) _Acanthophis._ (n) _Elapognathus._ (o) _Rhynchelaps._ (p) _Furina._ (a) =Ogmodon.= This genus is characterised by the maxillary bones extending forwards as far as the palatines, and bearing, in addition to the poison-fangs, 6-7 grooved teeth. The head is not distinct from the neck; the eyes are very small. The body is cylindrical, and covered with smooth scales in 17 rows. Tail short; subcaudal scales in 2 rows. _O. vitianus._--Snout elongate, pointed; 139-152 ventral scales; 27-38 subcaudals. Colour dark brown, lighter on the sides; belly brown or white, more or less spotted with black; tail black. Total length, 360 millimetres; tail 45. _Habitat_: Fiji Islands.
