subcontinnous I'adial ribs ; tliese are crossed by cords wliioli pi-oject on 

 the summits of tlie ribs, and which amount to nine on the last whorl and 

 four on the penultimate. Aperture trigonal, with a short 0[)en canal and 

 a wide eifnse sinus ; tlie varix projects a free limb towards the mouth ; 

 on the columella are three transverse plaits, which lengthen in ascending 

 order. Length 4-3 mm., breadth 2 mm. 



This is neai'ly related to L. hrdcJnjsjiird Hervier. From Lifuan 

 specimens of tliat form it differs by moi-e slender contour, more contraction 

 at the sutures, the ribs are more prominent, and the spirals more distinctlj' 

 bridge the inter-radial hollows. For it is suggested the snbgeneric group 

 of Acrii::tit.

 half com[)ose the protoconch. Colour pale buff, with a pale orange zone

 nodulous on the snout — on the last whorl twelve, and on the peimltimate 

 four. Aperture : — Mouth narrow, vertical ; vaiix not prominent, edge of
