Species 15. (Mus. Cuming.) 



RiciNDLA BELLA. Richi. testd subci/Undraceo-fusiformi, 

 ntrinque atienuald, basi contractd et paidulmii recurvd,

The PRETTY Eicinula. Shell cyUniUically fusiform, at- 

 tenuated at both ends, contracted and a little recurved 

 at the base, longitudinally concentrically ribbed, ribs 

 rather obtuse, close-set, transversely ridged, ridges 

 narrow, interstices striated ; pale rose, encircled by 

 two chesnut bands, on which the ridges are rose on 

 crossing the ribs. 



Eeeve, Pro. Zool. Soc, 1846. 



Eab. Island of Capid, Philippines (on the reefs at low 

 water); Cuming. 



An extremely pretty species of a pale rose colour, en- 

 circled with two rather broad bright chesnut bands, each 

 band having two ridges passing through them, exhibiting 

 a particularly neat appearance, from their being light on 

 crossing the ribs. 



Species 16. (Mus. Cuming.) 



RiCINTJLA fcniculat.y. Ricin. testd oblongo-ovatd, ob- 

 lique costatd, costis latis, solidis, subobsciiris, transver-

candeo-albicaide, liris lineisque aterrimis, aperturd 

 vivide violaced. 



The corded Eicinula. Shell oblong-ovate, obliquely 

 ribbed, ribs broad, solid, rather obscm-e, transversely 

 alternately ridged and lineated, ridges obtusely no- 

 dose ; blueish white, ridges and lines jet black, aper-

IM. ? 



A blueish wliite shell encircled with conspicuous black 

 ridges, the lower of which have a fine cord running be- 

 tween them ; and with a rich violet mouth. 



Species 17. (Mus. Cuming.) 



Eicinula heptagonalis. Ricin. testd fusiformi-ovatd, 

 basi paululum recnrvd, anfractibus transversim liratis

 fusco-albicaide, nigricante-fusco tinctd et foMciatd, aper- 

 turd albd. 



TuE seven-sided Eicinula. Shell fusifonnly ovate, a 

 little recurved at the base, whorls encircled with 

 ridges and squamate striae, angulated round the 

 upper part, longitudinally obtusely ribbed, ridges 

 compressly noduled over the ribs ; brownish-white, 

 stained and banded mth blackish-brown, aperture 

 wliite. 



Eeeve, Pro. Zool. Soc, 1846. 



Kab. Panama (under stones at low water) ; Cuming. 



An extremely interesting species, though scarcely coming 

 within the generic range of Ricimda ; it may, however, be 

 readily distinguished as such by the characteristic row of 

 nodulous denticles within the Up. 



Species 18. (Fig. a and b, Mus. Cuming.) 



Eicinula concatenata. Ricin. testd subfusiformi-ovatd, 

 anfractibus superne leviter concavis, transversim seriatim 

 tuberculatis, tuberculis confertis subquadratis et mucro- 

 natis, inlerstitiis striatis, striis mimdissime squamatis ;

 turd puipureo-violaced, vel aurantio-rufd.
