Edcithara alackis Sji. imr. 



(Plate xlvi., figs. 54, 55.) 



Cythara maculata Brazier, Proc. Linn. Soc. N. S.W., i., 1876, p. 160 (not 

 Mangelia maculata Reeve). 



Shell slender, fusiform, glossy. Whorls seven, of which one and 

 a half compose a small, smooth, helicoid protoconch. Colour white, 

 ornamented with four to six pale orange bands, appearing only in the 

 interstices, not on the ribs ; these sometimes coalesce from above and 

 below, thus replacing spiral by radial painting. Sculpture: — Radial ribs 

 are well developed, projecting as an angle on the shouldei, continuing 

 fi'om suture to base, and amounting to ten on the last whorl ; the spiral 

 threads are sharp on the upper whorls, where they are decussated by 

 radial striae ; gradually they vanish, till on the middle of the last whorl 

 the surface seems smooth to the eye, and only a few engraved spirals can 

 be found with a lens. Aperture: — The mouth is linear; the slight varix 

 encloses a small sinus, and extends in a narrow free edge; inner lip well 

 developed, with fifteen cross-bars ; beneath the varix are fourteen shoi-t 

 entering plicae. Length 11 mm., breadth 4 mm. 



This species is allied to E. angela, but is smaller, more pointed at the 

 ends, with fewer ril)s, and not so sharply angled at the sliouldei'. 



Hab. Queensland : — 5 to 8 fathoms, Mui'ray Island (type) ; Lizard 

 Island ; Bar of Annam River ; Dunk and Palm Islands (self); 30 fathoms,

Mangilia (Cithara) huhoisai Bouge and Dautzenberg, Journ. de Conch., 

 "ixi., 1914, p. 157. 



Of tliree specimens which I collected in Torres Straits in 1907 one 

 has eight and another fourteen ribs, thus easily linking avgela with 

 halansai, and supporting the above novel synonymy. 



Hall. Queensland: — 5 to 8 fathoms, Miii'ray Island (selfj.
