EUCYCLOTOMA NOBILIS sp. IIOV. 



(Plate Ivi., figs. 194, 195.) 



Shell large for the genus, lanceolate, rather solid. Colour crystalline 

 white, splashed irregularly with orange buff; nucleus buff. Besides a 

 two-whorled mucronate nucleus there are about seven whorls which wind 

 obliquely and are girt with solid projecting keels. Tlie turreted spire is 

 a little longer than the last whorl. Sculpture: — On the last whorl are 

 four nearly equal girdles; the second and fourth diminish as they ascend, 

 and vanish in a thread two whorls above ; the keel forming the basal 

 angle just emerges above the suture on the upper whorls; close set 

 perpendicular riblets bead the keels at the point of inteisection, and their 

 interstices are again traversed by smaller s[)iial thi'eads ; on the snout 

 are half-a-dozen spirals ; one specimen has a perfect varix half a whorl 

 behind the mouth ; the nucleus has close spiral threads I'eticulated by 

 finer radials. Aperture: — Outer lip flared, its edge dentate by the girdle 

 ends, and roughened by intermediate wrinkles ; sinus subsutural, ovate, 

 contracted at the entrance; canal short and bent; columella excavate 

 above and twisted below ; inner lip repiesented by a thin film of callus. 

 Length 16 mm., breadth 7 mm. 



This conies nearest to E. bicartnata,^'^^ from the Gilbert Archipelago, 

 but our shell at a corresponding length has three keels instead of two,
