9. On some New Species or NUCULACEZ IN THE COLLECTION 
or Hucu Cumine, Ese. By Sytvanus Haney. 
Lepa taytori. Testa elongata, antice aliquantum brevior et 
rotundato-lanceolata, postice attenuata et subrostrata ; sub- 
tenuis, compressa, nivea, densius longitudinaliter striata ; strie 
antice concentrice et elevate, mox acclinate et (certissime in 
valvula sinistra, ubi inferne prope plicam umbonalem planulatam 
demumque sublevigatam prorsus desunt) magis minusve oblique. 
Margo dorsalis uterque vir declivis ; anticus convexiusculus, 
posticus subretusus. Margo ventralis multum arcuatus, utrin- 
que subequaliter acclivis. Nates vix eminentes. Area dorsalis 
postica angusta, planulata, margine plice umbonalis depresse 
crenulato et valde prominente perspicue circumscripta; area 
dorsalis antica concentrice striata, subinconspicua. 
Long. 1,5, lat. 4 poll. 
Hab. Guatemala. 
Of the only three examples known to me, one belongs to Mr. Tay- 
lor and two to Mr. Cuming. The species approaches L. crenifera 
and L. electa. 
Lepa metcauFil. Testa elongata, valde inequilateralis, postice 
rostrata, compressa, albida, plice umbonalis elevate expers, lon- 
gitudinaliter striata (vel corrugata) : strie dense et argute 
ante radium anticum impressum remotiores et lamellose, postice 
autem elevate et valde oblique. LExtremitas lateris antici 
brevioris subangulata, superne eminentior, inferne oblique ro- 
tundata, lateris postici, sensim sed valde attenuati, angusta, 
obliqua, subtruncata, recurvata. Margines dorsales paululum 
declives: anticus convexiusculus ; posticus subrectus, denique 
autem incurvatus. Margo ventralis utrinque valde acclivis, 
antice oblique arcuatus, postice converus. Nates acute, satis 
prominentes. Aree dorsales sicut in L. crenifera. 
Long. 3, lat. 4 poll. 
Hab. ? 
Mus. Cuming, Hauley. 
This graceful shell, of which only two, and scarcely full-grown, in- 
dividuals are known to me, reminds one of L. erenifera and the young 
of L. electa. In the larger only of the specimens do the oblique strize 
extend to the crenated ridge. 
Youp1a woopwarpi. Testa subelliptica, valde inequilateralis, 
multum compressa, pertenuis, utrinque (presertim antice) hians, 
epidermide tecta valida, nitida, flavescente-olivacea, plice um- 
bonalis et radii impressi antici expers, sublevigata, rugis in- 
crementi tantum notata. LExtremitas lateris antici, producti, 
inconcinne rotundata ; lateris postici brevis rotundato-acumi- 
nata, et supra, potius quam infra medium sita. Margo dorsalis 
anticus vix declivis, principio subrectus, demum converus ; pos- 
ticus declivis, subrectus ; ventralis antice arcuatus et multum 
acclivis, in medio late converus, postice subarcuatim acclivis.
