 acuta, transversim liratd, liris numerosis, acutiusculis, 

 lird minore intercurrente, interstitiis striis longitudi- 

 nalibus elevatis cancellatis ; albd, maculis perpaucis

 The inter-ridged Mitre. Shell rather elongated, 

 spire sharp, transversely ridged, ridges numerous, 

 rather sharp, with a smaller ridge running between 

 each, interstices between the ridges cancellated with 

 longitudinal raised stria; ; white, stained with a very 

 few distant spots of faint orange-brown ; columella

Hab. Island of Masbate, Philippines (found in sandy 

 mud at the depth of four fathoms) ; Cuming. 

 The narrow intermediate ridge forms a prominent fea- 

 ture in this species. 



Species 71. (Mus. Cuming.) 

 Mitra clathrata. Mitr. testd subelongatd, spird tur- 

 ritd, acuminata -pr oductd ; anfractibus supern'e de- 

 presso-angulatis, longitudinaliter costatis, liris trans- 

 versis elevatis, confertis, clatkratis ; albd, anfractibus 

 fascia fuscescente unicd cingulatis ; columelld sub- 

 umbilicatd, quadriplicatd ; aperturd breviusculd. 

 The latticed Mitre. Shell rather elongated, spire 

 turreted, acuminately produced ; whorls depressly 

 angulated at the upper part, longitudinally ribbed, 

 latticed with close-set, raised, transverse ridges ; 

 white, whorls encircled with a single light brown 

 band ; columella slightly umbilicated, four-plaited ; 

 aperture rather short. 



Voluta unifasciata, Wood (not Mitra uuifascialis, 

 Lamarck). 



A white strongly latticed shell with a prominent brown 

 band round the middle of each whorl. 



Species 72. (Mus. Cuming.) 



Mitra lugubris. Mitr. testd ovatd, spird brevi, acutd ; 

 rugosd, striis impresso-punctatis cingulatd, suturis 

 salebrosis ; anfractibus supern'e albis, infra nigri- 

 cante-fuscis, columelld basique albis ; columella quin- 

 queplicatd. 



The mournful-looking Mitre. Shell ovate, spire 

 short, sharp ; rough, encircled with impressed 

 punctured stria?, sutures rugged and uneven ; 

 whorls white round the upper part, very dark 

 brown beneath, columella and base white ; colu- 

 mella five-plaited.

Hab. ? 



This is another well-characterized species for which 1 



have no locality. 



Species 73. (Mus. Cuming.) 



Mitra Zebuensis. Mitr. testd subfusiformi, nitidd, ba 

 sim versus sulcatd, liris planiusculis, confertis, sub 

 tilissime cancellatd, liris longitudinalibus fortioribus 

 albidd, anfractuum parte superiori maculis grandibu. 

 perpaucis castaneo -fuscis ornatd ; columelld quinque 

 plicatd. 



The Zebu Mitre. Shell somewhat fusiform, shining, 

 grooved towards the base, very finely cancellated 

 with rather flat close-set ridges, of which the longi- 

 tudinal are the stronger ; white, upper part of the 

 whorls ornamented with a few large chestnut-brown 

 spots; columella five-plaited. 



Reeve, Pro. Zool. Soc, 1844. 



Hab. Island of Zebu, Philippines (found on the reefs at 

 low water) ; Cuming. 

 The brown spots being situated around the upper part 



of the whorls give an irregular tessellated character to 



the spire.
