Hah. Island of Corrigidor, Bay of Manila (found under 

 stones at low water); Cuming. 

 This is the first species of an interesting group of shells 

 of which the Mitra Ziervogeliana forms the type, distin- 

 guished by their solid structure, the prominent develope- 

 ment of the columella! plaits, the presence of a callosity, 

 and the peculiar flattened surface of the outer lip. 



Species 134. (Mus. Deshayes, Paris.) 



Mitra livida. Mitr. testa subquadrato-ovatd, spird bre- 

 oiitsculd, acuta ; anfraetibus leevigatis, longitudinaliter 

 costatis, costis tumidis, inferne evanidis ; Uvido-olivaced, 

 balteo imiru angusto cingulatd, costis olivaceo-lutescen- 

 tibus ; columella quadriplicatd; labro leviter sinuato ;

Halt. ? 



I am much indebted to M. Deshayes for the loan of this 



very interesting species of which I know of no other spe- 



Species 135. (Mus. Cuming.) 



Mitra choava. Mitr. testa ovoid, solidd, glabra, spira 

 breoi; nigricante-fuscd, plicis albis ; columella concavd, 

 callositate armatd, quadriplicatd; labro peculiariter 

 planulato, superne canaliculato, intus crenulato. 



The coffee-berry Mitre. Shell ovate, solid, smooth, 

 spire short ; blackish-brown, plaits white ; columella 

 concave, armed with a callosity, four-plaited ; lip 

 peculiarly flattened, canaliculated at the upper part. 

 crenulated within. 



Reeve, Pro. Zool. Soe., 1844. 



Hah. Isle of Johanna, Mozambique Channel ; llennah. 

 The characters of the Mitra choava are very similar to 



those of the Mitree solidula and antkraeina, each species 



may, however, be fully distinguished by its difference of 



form and other minor peculiarities. 



Species 136. (Mus. Cuming.) 

 Mitra Ziervogeliana. Mitr. testa ovatd, solidd, crassk- 

 simd, ventricosd, spird brevissimd, acuta, suturis cre- 

 nato-crispis ; anfraetibus oblique concentrice rugosis, 

 bason versus transversim sulcatis, anfractu ultimo su- 

 perne tumido, inferne attenuato ; fused, plicis intersti- 

 tiisque niveis ; columella concaviusculd, callositate alba

Ziervocel's MlTRE. Shell ox ate, solid, very thick, ven- 

 tricose, spire very short, acute, sutures ornately 

 crisped; whorls obliquely concentricaUj wrinkled, 

 transversely grooved towards the base, last whorl 

 swollen at the upper part, attenuated at the lower ; 

 brown, plaits and interstices snowy-white; columella 

 rather concave, armed at the uppermost part with a 

 white callosity, four-plaited; lip peculiarly flattened,

 Voluta Ziervogeliana, Chemnitz. 

 Cancellaria Ziervogeliana, Lamarck. 



Hob. Island of Corrigidor, Hay of Manila (found under 

 stones at low water); Cuming. 

 This very remarkable shell, which Lamarck referred to 



the genus Cancellaria, is very properly placed by Kiener 



in the geuus Mitra.
