NtOTHA. 



name proposed for N. habellei. Reeve, not Orb., .V. Keenii, 

 Marr., which I figure from an author's specimen (lig. 282), N. 

 gemmulifera, A. Ad. (tig. 283). 



N. SPLENDIDULA, Duulcer. PI. III. figs. 284-287. 



White, shining, sharply granose by the crossing of the longi- 

 tudinal ribs by deeply incised lines; occasiouiiUy marbled with 

 light chestnut, or spotted with the same next the suture ; suture 

 deeply channeled. Length, -e-'IS inch. 



Philippines, Malacca, Polynesia. 



Very close to N. albescenti, and perhaps only a variety of that 

 species ; the tubercles are more sharp-set, the revolving lines 

 more distant and regularly spaced — not occasionally approxi- 

 mating in pairs as in nibexcens. The synonyms are N. semi- 

 ipanosa, Dkr. (fig. 285), N. ravida, A. Ad. (fig. 286), and N. 

 denaigranata , Keeve (fig. 287). 



N. nivoaa, Marrat, and N. >:rix])ala, Marrat, are unfigured 

 species compared by the author to this form. 



N. PAUPERATA, Lam. PI. 1(), figs. 288-291. 



Banded with chestnut on the periphery and at the base of the 

 body-whorl, columella and lip-margin sometimes tinged with 

 chestnut. Ribs becoming evanescent below the middle of the 

 body-whorl, cut into tubercles by the revolving lines, a row of 

 these tubercles below the suture, more prominent and separated 

 from the rest by a sulcus. Length. -o-'T-^ inch. 



S. Australia, Tasmania. 



N. lyrella. Beck (fig. 289), is a white or bleached specimen of 

 this species, not in good condition, and I think that NPmulti- 

 granosa, Dunker (fig. 290). is the juvenile, and N.caperata, Phil, 

 (fig. 2*71), a pigmy adult of the same species. 



N. soRDiDA, A. Ad. PI. 16, fig. 292, 



Yellowish, obscurely banded with light brown. 



Length, -65 inch. 



Philippines. 



The suture is somewhat channeled, the ribs rather sharp, the 

 revolving impressed lines rather faint. This, as well as the 

 following species may be only varietal forms of N. albeaceni'.
