DESCRIPTIONS OF NEW SPECIES OF MARINE SHELLS, 609 



incrassate outer lip, the base being somewhat truncate, and the thickening 

 extending to the columellar margin. 



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



A, testa profounde umbilicata, depresso-globosa, apice exserto, tenui an-> 

 fractibus 4, ultimo rapide accrescente,longitudinaliter obliquissime tenuicosta~ 

 tis, costis lsevibus, interstitiis sub lente striatulis, ultimo circa umbilicum 

 effosso, angulari, apertura ovata, labro exteriore simplice, paullulum incras* 

 sato. Long. 1'50, lat. 1 mm. 



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

 A . scalber, 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 longitudinally 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 VaniJcoro, Quoyand Gaimard, 

 which name has precedence by several years over Narica, Recluz. 

 9. Aclis atemeles, n. sp. PI. Fig. 10. 



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

 6. tumidis, apud suturas impressis sub lente tinuissime transversim striatulis, 

 apertura ovata, labro exteriore paullulum incrassato. Long. 3'25, lat. 

 1*25 mm. 



A finely striolate species, with ventricose whorls, six in number, apex obtuse* 

 mouth ovate, simple. The name suggested is the Greek word for "■ neglected," 

 from the inconspicuous appearance. 



10. Aclis EOA,n. sp. PI., Fig. 18. 



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

 anfractibus 6, paullum ante apicem irregularibus, ventricosis, apud suturas 

 multum impressis, fere lsevibus, vix nitentibus ; apertura ovata, peristomate 

 simplice, tenui, margine columellari obliquo. Long. 3*50, lat. 1*25 mm. 



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

 a little irregular and distorted, ventricose, and impressed at the sutures. 

 The aperture is ovate, the outer lip simple, and the columellar margin some- 

 what 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 DBNS-COLUBRI, n. Sp. PI, Fig, 19. 



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

 lucida, anfractibus 10, juxta, infra suturas zona lactea pellucente cinctis, 

 apertura oblique oblonga, labro marginem apud columellarem 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 

 allied to the European and British E, incurva, Renieri, E, distorca, Phil, fnon
