There is a species from the Persian Gulf which, though rather laiger, 

 seems to be otherwise identical, and which has been distributed as Mduiiilin 

 fairhiiiil:! and as Mangilia xcihda, neither of which names are applicable. 

 T liave also seen /'. hipi/rdiiiidntii, from the Isle of Pines, New Caledonia. 

 Along the Great Barrier Reef this sjiecies seems common and generally 

 distributed.

(Plate li., fig. 133.) 



Shell small, rather solid, lanceolate, constricted at the suture, and 

 contracted at the base. Colour uniform pale buff. Whorls eight, of which 

 thi'ee constitute the protoconch. Scul[)ture: — The ribs are seven to a 

 whorl, slightly oblique to the axis, low and round-backed, decreasing in 

 prominence as growth proceeds, continuitig from whorl to whorl ; the 

 spirals are numerous, closely-packed, grained, unequal threads extending 

 from the suture to the base; on the upper whorl two spirals predominate 

 to form a double keel, but these gradually decrease, so that when the last 

 whorl is i-eached the discrepancy between major and minor spirals has 

 nearly disappeared. Af)ertuie: — Mouth narrow, the varix equal to the 

 preceding ribs, and not rising above the plane of the suture; its outer 

 limb evenly striated ; within the apertuie a tubercle arises beneath the 

 sinus ; below that and under the free edge of the limb aie four minute 

 denticnles; columella perpendicular ; sinus small and shallow ; uanal short 

 and open. Length 5*5 mm., breadth 2 mm. 



This is like a miniature Mangelia multigranosa Schepman.
