IdeiitiHciitiou of iiiitigiiied species witlmiit iicces.s to u type is alsvays 

 a matter of uncertainty. Some Queensland specimens, here regarded as a 

 form of L. fiilla,!-, agree well with a series from Lifu. By being rather 

 sliorter, stouter, and nioi-e bi)hlly ribbed, both the above slightly differ 

 from a set from Reunion Island received under the name of (Ihjpho^toiua 

 fallax. As all my Australian specimens are very worn from the beaches 

 a drnwing of a Lifuan shell is here presented. 



Hah. Queensland : — Rocky Isle and Two Isles, both off Cape Flattery ; 

 Green Island (self). 



LlENAHIilA FAI;S1LI.S sp. imv. 



(Plate xlviii., tig. 92.) 



Shell small, very solid, biconical. Colour uniform white. Whorls 

 six. Protocouch of one and a half smooth rather depressed whorls. 

 Sculpture : — Ribs [)romiuent, discontinuous, set eight to a whorl ; spirals 

 are tine evenly spaced threads, eleven on the last whorl and four on the 

 penultimate; surface with a secondary sculpture of microscopic grains. 

 Apei'ture: — Mouth triangular-pyriform, of moderate bread tli ; varix pro- 

 minent, lip with a narrow free edge ; sinus so shallow as to seem a mere 

 bend from a profile view ; looking into the mouth it is made plain by a 

 tubercle on either side; within the lip are five entering plications; the 

 columella has a faint deep-seated fold. Length 45 mm., breadth 2 mm. 



This species is like a very diminutive Ueterocithard hilineata. 



Hub. Queensland : — 5 to 8 fathoms, Murray Island (type) ; 5 to 10 

 fathoms, Hope Island (self); 20 fathoms, off Endeavour Reef (McCulloch); 

 Darnley Island (Brazier).

My specimens from Tories Straits represent a diminutive form two- 

 thirds the length and stouter in proportion than typical Lifuan shells. 



Hab. Queensland : — 5 to 8 fathoms, Murray Island (self).
