 nally ribbed, white, girt with vows of greyish-brown

 Pyramidella plicala, Lamarck ; Kiener. 



Ilab. Island of Vanikoro, Philippines ; Cuming. 



The ribs of this species are continuous, smooth, and 

 distant ; the nodules at the angle are not very conspicu- 

 ous. It is the most regularly formed shell of the group 

 to which it belongs. 



Species 32. (Fig. a, b, Mus. Cuming.) 



Pykamidella PEOPINQUA. Pyr. testa ovald, brevi, ad 

 sjjiram acuminata, alba, fusco-grisescerUe varieyatd, 

 costis Uevibus, rectis, prope snturam vix nodulosis, in- 

 fra subevanidis, subdiiplicatis, inttrstitiis spiraliter 

 striatis, aperturd brevi, oblique pyriformi, labro iu- 

 crassalo. 



The appkoximate Pykamidella. Shell oval, short, 

 acuminated at the spire, white, variegated with 



greyish-brown, ribs smooth, straight, near the suture 

 very slightly nodulous, tending to divide and disap-

A. Adams, Sowerby's Thes. Couch. Pyramidella sp. 6. 



Hub. Rheetea, Society Islands (on the reefs) ; Cuming. 



More short and oval in form than P. auris-cati, the 

 nodules scarcely distinct, and a tendency in the ribs to 

 divide and sink towards the lower part of the whorls. 



Species 23. (Mus. Cuming.) 



I'viiAMlDELLA VARiEGATA. Fyr. testd ovali-oblongd, 

 albd, fusco-grisescerde variegatd, costis crebris, lavi- 

 bus, rectis, infra subevanidis, subduplicatis, iuterstitiis 

 spiraliter striatis, aperturd brevi, oblique pyriformi, 

 labro incrassato. 



The VARIEGATED Pyeamidella. Shell oval-oblong, 

 white, variegated with greyish-brown, ribs rather 

 close, smooth, straight, rather thinning and dividing 

 beneath, interstices spirally striated, apert\u-e short, 

 obliquely pyriform, outer lip thick. 



A. .Adams, Sowerby's Thes. Conch. Pyramidella sp. 8. 



Ishind of Masbate, Philippines (seven fathoms deep, in 

 sandy mud) ; Cuming. 



.Much more narrow and lengthened than P. propinqua. 

 It is marbled in the same way, but the ribs are closer.
