FUNAFUTI ATOLL. 



upper spire. These are the whorls stained chestnut, so dark as 

 to be almost black, in the New Caledonian specimens. The larger 

 whorls are closely corded by spiral lyrse, having smaller lyrae in 

 their interstices. Weak, longitudinal ribs undulate the central 

 whorls and appear on the last whorl, but vanish there before 

 reaching the periphery. The columella lip is broad and reflected, 

 obliquely ridged within and sharply bent above. The aperture 

 is perpendicular, ovate and grooved within. 



Rissoa joviana of Melvill and Standen* appears to me to be an 

 absolute synonym of Alaba fulva, Watson, f These and Aloha 

 striata, WatsonJ should enter the same genus as pyrrhacme. 

 Indeed I am not satisfied that all four names do not apply to 

 aspects of one polymorphic species. 



SCALA UEVOLUTA, Sp. nOV. 



(Fig. 7). 



Shell minute, white, with smooth coiled apex 

 and variced, solute, subsequent whorls. Whorls 

 six, of which the apical three are smooth and in 

 contact, the fourth commences to uncoil and the 

 remainder are widely separate. Varices eight 

 on the last whorl, with an anterior corner, 

 slightly elevated ; between the varices the shell 

 is smooth and glossy. Aperture broken in the 

 type example, but apparently circular. Length 

 3, breadth 1-5 mm. 



One specimen from the lagoon beach. 



The only shell for which the novelty might 

 be mistaken is S. hyalina, Sowerby. Judging 

 from Sowerby's d rawing that differs by being 

 much larger, broader, uncoiled to the tip, though less apart 

 latterly, and by more numerous and serrate varices. 



SCALA PAUMOTENSIS, Pease. 

 Tryon, Man. Conch, ix., 1887, p. 65, pi. xiii., fig. 16. 



Four specimens from the lagoon beach. Cited by Tryon from 

 Fiji, Gilberts, and Paumotus. 



SCALA SUBAUBICULATA, Souverbie. 

 Tryon, op. cit., p. 67, pi. xiv., figs. 21, 22. 



Four specimens from the lagoon beach correspond fairly well 

 with New Caledonian examples.
