204 MELVILL AND STANDEN: SHELLS FROM LIFU. 
approximate. The outer lip is denticulate within, sinus not 
extending beyond the middle of the outer lip. A considerable 
number of specimens. (xvepatos, dusky brown, from the colour). 
Clathurella episema sp. nov. (Pl. X., fig. 38). 
C. testa fusiformt, concinna, pallidé ochracea, anfractious 
guingue (exclusts apicalibus), distanter costulatis, spiraliter 
crassiliratis, lirts et costis albo-ochrets, interstitiis plus 
minusve ochraceofulvis, ultimo anfractu apud basim albes- 
cente, lirts tuberculatis, apertura oblonga, labro extus tncras- 
sato, tntus sex denticulato, margine columellari recto, simplice, 
sinu amplo, profundo. 
Long., 4°50, Lat., 1°25 mill. 
A neat little species, with the usual fusiform shape, and 
five whorls, exclusive of the apical, not present in our specimens. 
The whorls are clathrate, with longitudinal ribs and spiral liree, 
these being pale ochreous-white, the interstices darker ochre- 
ous. The last whorl 1s slightly prolonged and sculptured in the 
same way as the upper whorls ; one or two of the longitudinal 
ribs seem thicker than the others, giving a very slightly varicose 
appearance. The columellar margin is straight, simple, six 
denticled, outer lip incrassate, six denticled within, sinus deep 
and large. (erionpos remarkable). 
C. lita sp. nov. (Pl X., fig. 39). 
C. testa fustformt, parva, ochraceo-brunnea, delicatula, 
anfractibus sex, quorum duobus apicalibus, tumidts, nitids, 
ceterts ventricosts, obtusé crassicostatis, longitudinaliter, et 
spiraliler pluriliratis, interstitiis planatis, apertura late 
ovata, intus brunnea, labro extertore paullum tncrassato, 
albescente, sinu parvo, rotundato, margine columellari simplice. 
Long., 4, Lat., 1°50 mull. 
A small plain shell of simple character, not very dissimilar 
to some of our European species. The whorls are six; the lower 
ones ventricose, the two apical swollen, smooth and shining. 
Obtuse and thick ribs, longitudinally, ornament the shell, and 
these are spirally crossed by many conspicuous lire. The 
aperture is widely ovate, outer lip slightly thickened, whitish ;
