Species 82. (Mus. Cuming.) 



Mitra scutulata. Mitr. testd ornatd, spird breviusculd, 

 acuta ; anfractibus transversim impresso-striatis, an- 

 fractds ultimistriis mediants rrttnidis; o/icaceo-fuscd, 

 strigis alliitlis tie sii/uris in medio undatim descenden- 

 tibus, mactt/is albiilis perpauc/s pan-is tntcrspersis ;

The cobweb-makked Mitre. Shell ovate, spire rather 

 short, acute ; whorls transversely impressly striated, 

 middle stria; of the last whorl obsolete ; olive- 

 brown, with waved white streaks descending from 

 the sutures to the middle, interspersed with a few 

 small white spots ; columella four-plaited.

 Valuta scutulata, Chemnitz. 

 Variety? Valuta pica, Chemnitz. 



Halt. Province of North Ilocos, island of Luzon, Philip- 

 pines (found under stones at low water) ; Cuming. 



The white waved longitudinal streaks which adorn 

 this shell are sometimes completely divided into spots by 

 the transverse impressed lines. 



acute acuminata, leevigatd, ad basim striatd; niger- 

 rimo-fuscd, strigis a/bis augusl/s, subundatis, longi- 

 tudinaliter ornatd ; columella quadriplicatd, apertura- 

 fatice fusco tincta : labro sinuoso. 



The poor Mitre. Shell ovately oblong, spire sharply 

 acuminated, smooth, striated at the base ; blackish 

 brown, ornamented with slightly waved, narrow, 

 longitudinal white streaks ; columella four-plaited, 

 interior of the aperture stained with brown ; lip 

 sinuated.

 Valuta jiiiujirrctila, Linnaeus. 

 Mitra zebra, Lamarck (Ann. du Mus.). 



Hab. Province of South Ilocos, island of Luzon, Philip- 

 pines (found under stones at low water mark) ; 

 Cuming. 



This species is generally of smaller size than the 

 Mitra scutulata, from which it differs in being smooth, 

 and in the white streaks not being interrupted. 



Species S3. (Mus. Cuming.) 



Mitra Conus. Mitr. testa obverse corded, spird brevi, 

 acuta, ratliafim creuulato-liratd ct nodulosd ; Idci, 

 basim versus sulcatd ; albidd, lineis capillaribus ni- 

 gricantibus remotiusculis cingulatd, epidermide viri- 

 desccnte indutd : cnlumtlla se.cplicatd. 



The Cone Mitre. Shell diversely conical, spire short, 

 acute, radiately crenulately ridged and noduled ; 

 smooth, grooved towards the base ; white, encircled 

 with rather distant black hair-like lines, covered 

 with a greenish epidermis ; columella six-plaited. , 

 VolutaConus, Chemnitz, Conch. Cab., vol. x. pi. 150. 



f. 141.3 and 1416. 

 Mitra conulus, Lamarck. 



Hab. Island of Masbate, Philippines (found in mud at the 

 roots of mango-trees) ; Cuming. 

 I do not see what reason Lamarck had for making a 



diminutive of the specific name given to this shell by 



Chemnitz. 



Species 84. (Mus. Cuming.) 

 Mitba i'aupkrcula. Mitr. tcstd ovato-oblongd, spird 



Species Sj. (Fig. a and b, Mus. Cuming.) 

 Mitra amphorella. Mitr. teste! ovato-oblongd, spird 

 subobtusd ; lacigatd, basim versus su/catti ; olivaceo- 

 fttscd, niacu/is perpaucis albis prope apicetn ad basim- 

 que ornatd, au/ractutim limbo superiore lutcscen/e ; 

 columella, /uai/riji/irata'.stijiernr ca/lusii; labro sinuoso. 

 The Amphora-shaped Mitre. Shell ovately oblong, 

 spire rather obtuse ; smooth, grooved towards the 

 base ; dark olive-brown, ornamented with a few 

 white spots near the apex and at the base, upper 

 edge of the whorls yellowish ; columella four- 

 plaited, with a callosity at the top ; lip sinuated. 



Variety p. (Fig. 85 b.) 



Testa angttstior, plus sulcata, mac/t/is albis frequentiori- 

 bus. 



Shell narrower, more grooved, white spots more fre- 

 quent. 



Lamarck, Anim. sans vert., vol. vii. p. 316. 



Hab. Islands of Luzon and Zebu, Philippines (found 

 under stones at low water) ; Cuming. 



The variety /3. exhibits an interesting link between 

 this species and the Mitra scutulata.
