MEr-VILL : NEW MOLLTTSCA FROM THE PERSIAN GULF, ETC. to 



Mtjceonalia lepida,' n.sp. PI. VII, Fig. 8. 



M. testa parva, ovato-fusiformi, vitrea, delicata, lactea, polita, 

 laevigata, anfractibus 8-9, quorum 3-4 apicales parvi, mamillati, 

 apice ipso heterostropho, cfetcris ad suturas vis impressis, rapide 

 accrescentibus, anfractu ultimo tertiam totius longitudiuis partem 

 prsebente, apertura ovata, labro paullum incrassato, columella crassa, 

 simplice. Long. 3, lat. 1 mm. 



A neatly-formed Mucronalia, of thicker and more compact substance 

 than its ally, M. oxytencs, Melv., from the same locality. 

 Strnola aperanta,- n.sp. PI. VII, Fig. 9. 



S. testa attenuato-fusiformi, alba, nitida, polita, solidiuscula, 

 anfractibus ad 10-11, quorum apicales 2 parvi, quam maximo 

 heterosti'ophi, vitreo - globulares, caeteris apud suturas multum 

 canaliculato-impressis, ct paullum gradatis, quatuor ultimis anfractibus 

 rectis, uniforraibus, ultimo paullum producto, apertura ovato-rotunda, 

 labro baud efluso, ad basim producto, margine columellari recto, fortiter 

 uiiiplicato. Long. 6, lat. 1-25 mm. 



This species might easily be confounded -with EidimeUa carmanica, 

 M. & S., which occurs with it in equal plenty. It is, however, of 

 a more gracefully attenuate contour, with aperture smaller proportion- 

 ately. The columella, too, is strongly once-plicate, in the Eulimella it 

 is simple. 



Syrnola clavellosa,^ n.sp. PL VII, Fig. 10. 



S. testa parva, alba, nitida, polita, angusto-fusiformi, solidula, 

 anfractibus 9-10, quorum 2-3 apicales raagnopere heterostro|)lii, 

 conspicui, bulboso -globulares, caeteris apud suturas canaliculato- 

 impressis, lineis interiiis 4-5 spiraliter prseditis, apertura ovata, 

 labro paullum producto, margine columellari fortiter uniplicata. 

 Long. 4-5, lat. 1 mm. 



A very narrowly fusiform species, the heterostrophe apical whorls 

 unusually swollen, globular, club-like, and conspicuous in proportion 

 to the size of the shell. The internal spiral lines, showing opaquely 

 through the surface, are four or five in number, broadest just below 

 the sutures. Very faint spiral chestnut banding appears in some 

 specimens. It is one of the smallest Syrnolce, and not, I think, verj' 

 comparable with other forms of the genus. 



TtJRBONiLLA (Pyrgostylis) Delta, n sp. PL VIII, Fig. 30. 



T. testa breviter fusiformi, minuta, albo-straminea, anfractibus 8, 

 quorum 2 apicales globulosi, vitrei, sublasves, caeteris ad suturas 

 multum impressis, tumidulis, arete Itevicostatis, interstitiis laevissimis, 

 apertura ovali, peristomate subeffuso, continue, columella obscure 

 plicata. Long. 3, lat. 1 mm. 



i7"ff3.— Persian Gulf, Bushire, 6-10 fathoms. 



Conspieuous for its ventricose whorls, yellowish colour, and 

 shortened spire. 



^ Lepidns, 'neat, pleasiiifj.' 



- airepavTos, ' countless,' from its frequeucy. 



^ Clarellosa, dim. of claviis, ' a club,' from the form.
