FUNAFUTI ATOLL. 



Taken by Garrett at Fiji, Samoa, Cook's, Society, and Paumotu 

 Groups. 



TURRICULA NODOSA, Swainson. 



Tryon, loc. cit., p. 193, pi. Ivi., figs. 638-641 ; Garrett, loc. cit., pp. 

 6, 53. 



One dead specimen from Funafuti. 



Garrett records this from Fiji, Tonga, Samoa, Gilberts, Carolines, 

 Cook's, Society, Paumotus, and Hawaii. Melvill and Standen 

 observe it from the Loyalties.* There is an example in this Museum 

 from Niue. 



TURRICULA PILSBRYI, sp. nov. 

 (Fig. 40). 



Shell fusiform. Colour orange-buff, with a rosy apex. Whorls 

 five, plus the protoconch. Sculpture on the last whorl are six 

 roundly swelling arcuate ribs, which arise at the suture and 

 terminate at the basal constriction, but dis- 

 appear on the final half whorl ; the anti- 

 penultimate has thirteen ribs. On ascending 

 the spire, the ribs become comparatively more 

 prominent, and on the earliest whorl are 

 sharply constricted and angled at their upper 

 third. On each whorl they alternate with 

 those above and below. Between the ribs 

 appear delicate and evenly-spaced, spiral 

 grooves. Seven or eight broad, close, flat- 

 topped lyrse are obliquely wound around the 

 base. Protoconch two-whorled, globose, pro- 

 jecting on the right side, smooth ; anteriorly 

 a spiral groove forecasts the constriction of a 

 later whorl. In the unique specimen the lip 

 is broken. The columella bears a tubercle at 

 the posterior angle, it is then excavated ; the 

 moderately straight pillar carries four, con- 

 spicuous, projecting plaits ; a callus is spread 

 ever the preceding whorl. The throat is on its outer wall 

 corrugated by a dozen raised spiral lines. Length 6, breadth 2| 



Fig. 40. 



Taken by the tangles hauled up on the outer western slope of 

 the atoll, in eighty to forty fathoms, associated with Gorgonidce, 

 Thetidos, etc. 



This species is a member of the subgenus Pusia, and seems 

 well defined by the uniform colour, smooth, wave-like ribs, and 

 basal constriction.
