280 DR. P. P, CARPENTER ON NEW SPECIES [ Mar. 14, 
NARICA INSCULPTA. 
N. ¢. “N. apertee”’ simili, sed magis compacta ; paullum angus- 
tiore, umbilico tamen majore ; lineis spiralibus circ. xxvi. dis- 
tantibus insculptis cincta, quarum x. in anfr. penult. monstran- 
tur ; postice lineis incrementi viv conspicuis. 
Long. *3, long. spir. ‘08, lat. °28 ; div. 100°. 
Hab. Acapulco, on Ostrea iridescens, Rowell. 
The Cape St. Lucas species (vide Ann. Nat. Hist. 1864, xiii. p. 476) 
has the sculpture in irregularly raised lirnle, while this has minute 
grooves chiselled out of a smooth surface. It appears that the San 
Franciscans import the huge tropical oysters in large quantities, 
their own species having the coppery flavour which Americans dis- 
like in the British species. From the outside of the valves, Mr. 
Rowell obtained this and many other interesting species. 
DRILLIA EBURNEA. 
D. ¢. turrita, carneo-albida, tenuiore, levi, maxime nitente; mar- 
ginibus spire rectis; anfr. nucl.? . . . [decollatis} ; norm. 
circ. ix., postice planatis, supra suturas appressis, medio satis 
excurvatis ; hic et illic rugis radiantibus, obsoletis, irregula- 
ribus exsculpta; basi prolongata, canali conspicuo, aperto ; 
sinu postico minore, in sulco lato, haud definito, spiram ascen- 
dente sito; labro acuto; labio indistincto ; columella planata. 
Long. 1°3, long. spir. °8, lat. 45; div. 30°. 
Hab. Near Gulf of California (teste Rowell). 
Easily recognized by its smooth glossy aspect and French-white 
colour; the notch lying along a broad spiral channel, which throws 
the junction of the whorl as it were up the suture. 
MANGELIA ALBOLAQUEATA. 
M. ¢. solida, turrita, alba, rudi, marginibus spire rectis; anfr. 
nucl.? . .. [decollatis|; norm. circ. ix. subrotundatis, costis 
cire. xi.-xv., declivibus, satis angustis, postice obsoletis, lineis 
subregularibus spiram ascendentibus ; lirulis spiralibus anticis 
crebris, postice obsoletis ; basi elongata; labro? ... ; labio 
calloso ; sinu postico majore, suturam attingente. 
Long. *88, long. spir. 55, lat. *34; div. 30°. 
Hab. Panama (teste Rowell). 
Described from an imperfect and worn specimen, but easily recog- 
nized by its ivory-white colour, and ribs in slanting rows, as though 
the creature were roofed with white tiles. It was erroneously quoted 
in the Brit. Assoc. Rep. 1863, p. 669, as a Drillia. 
EULIMA FALCATA. 
E. ¢. valde tereti, valde curvata, alba, politissima, solidiore, 
marginibus spire meniscoideis ; anfr. nucl.? . . . [detritis} ;- 
norm. circ. X., planatis, lente augentibus ; axi hamata ; suturis 
indistinctis ; basi elongata, haud tereti; apertura pyriformi, 
antice latiore ; labro acuto; labio tenui, appresso.
