MELVILL : NEW MARINE SHELLS FROM BOMBAY. Ill 



The nearest approacli to this species seems to be H. conifera 

 (Schwartz). It is principally distinguishable by its straight, smooth 

 ribs, and extremely incrassate outer lip, the base being somewhat 

 truncate, and the thickening extending to the columellar margin. 



8. Adeorbis vanikoroides, n.sp. PI. YIII, Fig. 14. 



. A. testa profunde umbilicata, depresso-globosa, apice exserto, tenui, 



J anfractibus 4, ultimo rapide accrescentc, longitudinaliter obliquissime 



tcnuicostatis, costis Icevibus, interstitiis sub lente striatulis, ultimo 



circa umbilicum effosso, angulari, apertura ovata, labro exteriore 



simplice, paullulum incrassato. Long. 1-50, lat. 1mm. 



Extremely small, but very characteristic. Of the same character as 

 A. scaher, Phil., a Central American shell, but differing entirely in 

 form ; the apex is conspicuously exserted so far as the first two 

 whorls are concerned, the last whorl is large, and entirely longi- 

 tudinally obliquely ribbed, the interstices between being very finely 

 striate. The umbilicus is profound, angularly ridged above, and the 

 aperture ovate. The specific name suggests a superficial resemblance 

 in miniature to species of J^anikoro, Quoy and Gaimard, which name 

 has precedence by several years over Narica, Eecluz. 



9. ACLIS ATEMELES, U.sp. PI. YIII, Fig. 10. 



A. testa angusta, attenuata, fusiformi, delicatula, albido-cinerea, 

 anfractibus 6, tumidis, apud suturas impressis, sub lente tenuissime 

 transversim striatulis, apertura ovata, labro exteriore paullulum 

 incrassato. Long. 3"25, lat. 125min. 



A finely striolate species, with ventricose whorls, six in number, 

 apex obtuse, mouth ovate, simple. The name suggested is the Greek 

 aTrj/.ieXij's, 'neglected,' from the inconspicuous appearance. 



10. AcLis EOA, n.sp. PI. VIII, Fig. 18. 



A. testa oblongo-fusiformi, delicatula, semipellucida, lactea, apice 

 obtuso, anfractibus 6, paullum ante apicem irregularibus, ventricosis, 

 apud suturas multum impressis, fere Itevibus, vix nitentibus ; apertura 

 ovata, peristomate simplice, tenui, margine columcUari oblique. 

 Long. 3-50, lat. l-25mm. 



A thin, semipellucid, milky shell, without any gloss, six-whorled, 

 the whorls a little irregular and distorted, ventricose, and impressed 

 at the sutures. The aperture is ovate, the outer lip simple, and the 

 columellar margin somewhat oblique. 



It does not yield in beauty to the other known species, nearly all 

 of which are exquisite in form. The specific name is given from its 

 Eastern habitat. 



11. EULIMA DENS-COLUBRI, U.Sp. PI. VIII, Fig. 19. 



E. testa parva, politissima, attenuato-curvata, apud basim latiore, 

 translucida, anfractibus 10, juxta, infra suturas zona lactea 

 pellucente cinctis, apertura oblique oblonga, labro marginem apud 

 columcllarem paullum incrassato. Long. 5 mm. sp. maj., lat. 1"75 mm. 



A small incurved species, ten-whorled, smooth, polished, but trans- 

 lucent, the basal portion being broader in proportion. This form is
