The diminutive Purpura. Shell ovate, somewhat fusi-

 cularly nodided, lip denticidated within; piu-ple-black, 

 nodules white, interior of the a])erture dark pm-ple.

Hob. Lord Hood's Island (on the reefs); Cuming. 

 Distinguished by its conspicuous wliite nodules. 



Species 62. (Mus. Cuming.) 



Purpura diadema. Purp. testd suhfrniformi-ovatd, spird 

 aciiminatd; anfractibus svperne depresm, siMUUer 

 impresso-striatu, striis obsolete punctaUs ; spiraUter 

 hkar'matis, eariuis tubercidatis, tiiierciilis compressis,

The diadem Purpura. ShcU somewhat fusiformly 

 ovate, spire acuminated ; whorls depressed roimd the 

 upper part, finely impressly striated, striae obsoletely 

 punctm-ed ; spirally double-keeled, keels tubereulated, 

 tubercles compressed, erect ; light bay colom-, interior 

 white. 



Eab. Payta (on the reefs) ; Cuming. 



Easily recognized by its compressly tubercled keels. 



Species 63. (Mus. Cuming.) 



Purpura costularis. Purp. testd fasiformi, longitudl- 

 nallter plicato-costatd, transversim creberrinw et siib- 

 tilissiine liratd, lirk minutissime squamatis ; aperturd 

 parvd, labro serrato ; violascente-albd, colimelld et 

 aperturce fame vivide violaceis. 



The small-ribbed Purpura. Shell fusiform, longitu- 

 dinally plicately ribbed, transversely very closely and 

 finely ridged, ridges very minutely scaled ; apertui-e 

 small, lip serrated; violet-tinged white, columella 

 and interior of the aperture deep violet. 



De Blainville, Nouv. Ann. duMus. pi. 11, f. 9. 

 Murex costularis, Lamarck. 



Hab. Isle of Masbate, Philippines (under stones at low 

 water) ; Cuming. 

 I include this shell in the present genus on account of 



its affinity with the P. galea, violacea, &c. 



Species 64. (JIus. Taylor.) 

 Purpura unifascialis. Purp. testa ovatd, teimi, ven- 



tricosd, anfractibus transversim tenuissime striatis, 

 hiseriatim. nodosis, supertie depressis ; columelld an- 

 giistd, aperturd dilatatd, siditiliter sidcatd ; spadiceo- 

 fused, fascid nlbidd angustd medio ciugulatd, apertura 

 sulcis prope labriim riifescentibus. 



The singled-banded Purpura. Shell ovate, thin, ven- 

 tricose, whorls transversely very finely striated, en- 

 cii'cled with two rows of nodules, depressed round 

 the upper part ; columella narrow, apertm-e dUated, 

 finely grooved ; light bay colour, encircled round the 

 middle by a nai-row whitish band, gi-ooves of the 

 aperture red near the lip. 



Lamarck, Anim. sans. vert. (Deshayes edit.) vol. x. p. 80. 



Eab. ? 



Tliis is not a variety of the P. hamastoma, as M. Kiener 

 supposes, but a very excellent species, distinguished, 

 without reference to the banded style of colouring, by 

 its light inflated gi-owth and other peculiarities of detaU ; 

 it approaches very closely to the P. BlainviUii, but the 

 aperture is proportionably larger and more dilated, the 

 columella is not, moreover, edged with red. The shell 

 before me answers with pecuhar accm-acy, ii-respective of 

 the band, both ivith Lamai-ck's description, and the figure 

 cited by him in the 'Encyclopedic Methodique., 



Species 65. (Mus. Cuming.) 

 Purpura galea. Purp. testd abbreviato-ovatd, Pi/rtda- 

 formi, ampUter umbilicatd, spird Irevi ; avfractibus, 

 longitiidimliterplicatis, siipenie plano-depressli, trans- 

 versim costatis, et creberrime subtiliter liratis, liris 

 mimdissime squamatis; albd, coccineo pallidissime 



tinctd. 

 The helmet Purpura. Shell abbreviately ovate, Pyrula- 



shaped, largely umbilicated, spij-e short; whorls 



longitudinaUy plicated, flatly depressed round the 



upper part, transversely ribbed and very closely finely 



ridged, ridges very minutely scaled; white, very 



faintly tinged with scarlet. 



Murex galea, Chemnitz, Conch. Cab., vol. x. p. 237. 

 pi. 160. fig. 1518, 1519. 



Pyrida abbreviata, Lamarck. 



Purpura abbreviata, Kiener. 

 Hab. Island of Luzon, Philippines (under stones at low 



water); Ciuning. 

 This remai-kable species is very closely aUied, genericaUy, 

 to the Pyrula Mawce, but its affinity with the Purpura 

 violacea and others, renders the present the most appro- 

 priate genus for its reception.
