1. DescriPTIONS OF SOME NEW SPECIES OF OVULUM IN THE COLLEC- 
Tron oF Mr. Cumine. By G. B. Sowersy, Jun. 
1. Ovutum umsBiticatum (Thes. Conch. pl. 101. f. 88,89). Ovud. 
testd globosd, subpyriforme, alba, roseo pallidé tincto, dorso ad 
extremitates rubro lineato, ad terminum posticum umbilicato ; aper- 
turd subapertd; labio externo angustato umbilicato; aperturd 
subapertd ; labio externo angustato intis crenulato postice labium 
internum superante ; labio interno postice tumorem elevatum den- 
ticulatum ferente, ad canalem tineari, antice bicostellatd, ad cana- 
lem uniplicato. 
Agreeing with QO. margarita in general appearance, but the outer 
lip is thinner, the mouth wider, the upper callosity elevated and den- 
ticulated. There is also a small urabilicus behind the posterior ter- 
mination of the outer lip. 
Hab. Ticao, Philippines; by Mr. Cuming. 
2 Ovuxnum tancroratum (Thes. Conch. pl. 100. f. 35, 36). Ovul. 
testa elongata, angustatd, minutissime striatd, aurantio-rubescente, 
seu albidd, canalibus subproductis, emarginatis ; aperturd angus- 
tatd ; labio externo planulato crasso, breviusculo, antice angulatim 
flexuoso ; labio interno tumido rubro longitudinaliter marginato, 
postice ad canalem producto, subtortuoso, antice intis longitudi- 
naliter sulcato, uniplicato, ad canalem angusto, rectiusculo, acumi- 
nato. 
A remarkable shell, presenting the appearance of O. aciculare very 
much lengthened. The aperture is narrow, excepting towards the 
anterior, where the outer lip is bent out: the under surface is flat, 
the inner lip edged with a reddish line. Collected by Mr. Cuming. 
Hab. Sorsogon, Isle of Luzon, Philippines. 
There is a white variety of this species (?) from Molucca. 
3. Ovutum unipiicatum (Thes. Conch. pl. 100. f. 30, 31, 32). 
Ovul. testd elongata, subcylindricd, pellucidd, minutissime striata, 
aurantid, seu violaced, antice subacuminatd, postice subrotundata ; 
dorso margine distincto ; aperturd subaperta; labio externo pau- 
lulim incrassato, ad extremitates recedente, antice subangulato, 
ad canalem emarginato ; tabio interno intis subdepresso, postice 
spiraliter uniplicato, ad canalem tortuo, versus labium externum 
deflecto, antice subtortuo acuminato. 
Specimens of the pale violet variety were obtained by Mr. Cuming 
from near Charleston, South Carolina; a darker one from Rio 
Janeiro. 
This species resembles O. aciculare, but is more acuminated at the 
anterior extremity; it is rather more ventricose, and finely striated. 
The spiral fold near the anterior canal is more decided and less ob- 
lique, and the edge of the canal above it invariably leans towards 
the outer lip.
