52 MOTH A. 



mime proposed for N. IsabeHei. Reeve, not Orb.. A'. Keenii, 

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

 yemmuliffirn . A. Ad. (tig. 283). 



X. SPLEXDIDULA, D linker. PI. 16, iigs. 284-287. 



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

 tudinal ribs by deeply incised lines; occasionally marbled with 

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

 deeply channeled. Length. -6-- 7 5 inch. 



Philippine*, Malicca, Polynesia. 



Very close to N. albescent, 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 albescens. The synonyms are X. seri- 

 tranosa, Dkr. (fig. 285). N. ra-vida.* A. Ad. (tig. 286), and ,V. 

 densigranqta, Reeve (tig. 287). 



N. nivoxa, Mai-rat, and X. rrixpata, Marrat, are unligured 

 species compared by the author to this form. 



X. PAUPERATA, Lain. PI. 16, tigs. 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, -5-'75 inch. 



8. Australia, Tanrn> 



A', hjrella. Beck (tig. 289), is a white or bleached specimen of 

 this species, not in good condition, and I think that N. multi- 

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

 (fig. 271), a pigmy adult of the same species. 



X. SORDIDA, A. Ad. PI. 16, fig. 292. 



Yellowish, obscurely banded with light brown. 



Length, -65 inch. 



Philippine*. 



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. albescent
