474 FUNAFUTI ATOLL. 



excavate above, anteriorly ridged by the entrance of three of the 

 basal cords which ascend obliquely ; canal open, broad, short, 

 truncated ; outer lip much thickened externally by a heavy varix 

 which is crossed and denticulated by the spiral sculpture ; within 

 the varix, and at right angles to it, the aperture proper has a 

 second raised lip, and within that again are three large, equidistant 

 tubercles, the largest and most prominent of which is that next 

 the sinus ; the anal sinus is moderately deep, scarcely mounts on 

 the preceding whorl, and spreads a callus across two ribs. Length 

 5, breadth 2| mm. 



One example, procured in eighty to forty fathoms by the tangles, 

 with the preceding species. 



MANGILIA HIMERTA, Melvill & Standen. 

 Melvill & Standen, Journ. Conch., viii., 1896, p. 281, pi. ix., 



fig. 17. 



One example from the lagoon beach. Only before recorded 

 from Lifu. 



CLATHURELLA LACTEA, Reeve. 

 Reeve, Conch. Icon. L, 1843, Pleurotoma, pi. xv., sp. 123. 



One specimen from the lagoon beach answers well to Reeve's 

 illustration. 



CLATHURELLA CLANDESTINA, Deshayes. 

 Tryon, loc. cit., p. 298, pi. xix., fig. 67 ; pi. xx., fig. 81. 



One specimen from the Funafuti lagoon, slighter and paler 

 than the typical form. It is only 4 mm. long, and has a buff 

 tip and two obscure buff bands on the back of the last whorl. 



Pease found this in the Paumotus, Garrett in Fiji, and Hadfield 

 at Lifu.* I collected a large form, 7 mm. in length, at Milne 

 Bay, British New Guinea. According to the descriptions, C. 

 pumila, Mighels, seems scarcely separable. 



CLATHURELLA APICALIS, Montrouzier. 



Montrouzier, Journ. de Conch., ix., 1861, p. 277, pi. xi., fig. 1. 

 Two worn specimens from the beach of the Funafuti lagoon. 



Tryon f relegates this to the synonomy of C. felina, Hinds. As 

 Reeve's miserable figure of this permits no comparison, I accept 

 without criticism Hervier's assurance} that it is distinct.
