GURALEUS TENUILIRATUS Angas.

Mangelia tenwilirata Hedley, Mem. Austr. Mus., iv., 1903, p. 392. 
This species has a sculpture of minute grained threads. In the British 
Museum is a single specimen presented by Angas, evidently the type, but 
not so marked. The references of this species to the Gulf of Oman and 
to the Gulf of Suez need confirmation. 
Hab. N.S. Wales:—5 fathoms, Goat Island, Port Jackson (type); 
Port Stephens (Brazier); 41 to 50 fathoms, Cape Three Points; 63 to 75 
fathoms, Port Kembla (‘“ Thetis”). 
Macreota Hedley. 
Macteola Hedley, Journ. Roy. Soc. N.S.W., li., 1918, suppl. p. M. 79. 
This name is proposed for a genus of the Mangiliine, in which the 
aperture has not acquired armature, and in which the lip is not flexed. 
Prominent radial ribs are over-ridden by fine beaded spiral threads. The 
apex is mucronate, with smooth whorls. Characteristic is a colour scheme 
of a peripheral zone of brown or black or orange, sometimes broken into 
a series of dots or dashes. Type Purpura (Cronia) anomala Angas. 
Besides the Australian species here enumerated, an extra-limital 
species, Mangilia thiausotes Melvill and Standen, may also be included in 
Macteola.

In fresh specimens a delicate grain sculpture is visible under the lens. 
The colour varies. There may be only a peripheral row of separate 
intercostal brown spots, or beneath these there may run a continuous 
orange zone, anterior to which the shell may be faintly suffused with pink.
