MITKA.— Plate XV. 



Species 111. (Mus. Cuming.) 



Mitba variegata. Mitr. testa suboblongo-ovatd, trans- 

 versim regulariter sulcatd, anfractuum limbo superiori 

 subobsolet'e crenulato ; albidd, olivaceo-spadiceo ne- 

 bulatd et variegatd ; columella quinqueplicatd.

 transversely regularly grooved, upper edge of the 

 whorls somewhat obsoletely crenulated ; whitish, 

 clouded and variegated with pale olive-bay ; colu- 

 mella five-plaited. 



Reeve, Pro. Zool. Soc, 1844. 



Hab. Islands of Ticao and Mindanao, Philippines (found 

 on the reefs at low water) ; Cuming. 

 The whorls of this shell are very slightly angulated, 



and the clouded variegated painting only appears below 



the angle. 



Species 112. (Fig. a, Mus. Brit. ; Fig. b, Mus. Norris.) 



Mitra serpentina. Mitr. testd ovato-fusiformi, soli- 

 diusculd, transversim regulariter impresso-striatd, 

 striis prominente excavato-punctatis ; albd, aurantio 

 subindistincte tinctd et zonatd, lineis rufo-fuscis ob- 

 lique undatis, serpentinis, longitudinaliter pictd ; co- 

 lumella sexplicatd. 



The serpent-marked Mitre. Shell ovately fusiform, 

 rathersolid, transversely regularly impressly striated, 

 striae prominently excavately punctured ; white, 

 rather indistinctly stained and zoned with orange, 

 longitudinally painted with obliquely waved, ser- 

 pentine, red-brown lines ; columella six-plaited. 



Lamarck, Anim. sans vert., vol. vii. p. 306. 



Hab. Island of Burias, Philippines (found in sandy mud 

 at the depth of seven fathoms) ; Cuming. 

 This very beautiful species may be recognised by its 



orange-tinted bands, and the serpentine character of its 



longitudinal markings. 



Species 113. (Mus. Norris.) 

 Mitra cerulea. Mitr. testd subfusiformi-oblongd, trans- 

 versim regulariter sulcata, sulcis angustis, punctu- 



ratis; cerulescente-albicante, anfractu ultimo, fascid 

 latissimd ceeruled, marginibus albimaculatis, cincto ; 

 busi et aperture fauee aurantio- fuscescentibus ; colu- 

 mella quinqueplicatd, umbilicatd. 



TnE blue Mitre. Shell somewhat fusiformly oblong, 

 transversely regularly grooved, grooves narrow, 

 punctured ; blueish white, last whorl encircled with 

 a broad blue band, the edges of which are spotted 

 with white ; base and interior of the aperture 

 orange-brown ; columella five-plaited, umbilicated. 



Reeve, Pro. Zool. Soc, 1844. 



Hub. Islands of Ticao and Capul, Philippines (found on 

 the reefs at low water) ; Cuming. 



The white flake-like spots which appear on the upper 

 edge of the blue band of the last whorl are just visible 

 on the whorls of the spire above the sutures. 



Species 114. (Mus. Cuming.) 



Mitra tristis. Mitr. testd oblongd, spird breviusculd, 

 acuminata, Itsvigatd, basim versus sulcatd, longitudi- 

 naliter obsolete plicato-costatd ; nigricante-fuscd, 

 lined albidd cingulatd, costis superni albidis, epider- 

 mide corned indutd ; columella quailriplicatd ; aper- 

 ture fauee albido-purpurascente ; labro in medio con- 

 tracto. 



The sad Mitre. Shell oblong, spire rather short, acu- 

 minated, smooth, grooved towards the base, longi- 

 tudinally obsoletely plicately ribbed; blackish brown, 

 encircled with a white line ; upper part of the ribs 

 white, covered with a horny epidermis ; columella 

 four-plaited ; interior of the aperture whitish pur- 

 ple ; lip contracted in the middle. 



Swainson (Broderip), Pro. Zool. Soc, 1835. 



Hab. St. Elena West Columbia, and Gallapagos Islands 

 (found in sandy mud at the depth of from six to 

 ten fathoms) ; Cuming. 



This shell, which has a very sombre appearance, may 

 be recognised by the coronated-like character imparted 

 to the spire by the white ends of the ribs which are 

 almost obsolete.
