568 MR. G. B. SOWERBY ON NEW SHELLS FROM [DeC.,18, 



curvus ; columella late expansa, irregulariter pustulata et plicata ; 

 labrum incrassatum, rejlexum, liris brevibus dentiformibus mu- 

 nitum. 



Long. 45, maj. dium. 23; upert. long. 29, maj. lat. 5 millim. 



Hab. Japan. 



An interesting new species, intermediate in form between O. can- 

 cellata (Sowb.) and O.ponderosa (Hanley). The former is common 

 at Hongkong, and the latter, quoted in the Paetel catalogue as inhabit- 

 ing Japanese waters, is extremely rare. Compared with O. cancel- 

 lata, the new species is much more gibbous and pyriform, and the 

 transverse ridges are not raised into piickly scales on the ribs ; the 

 colouring is also different, consisting principally of angular blotches 

 of light and dark brown. Compared with O. ponderosa it is much 

 higher in the spire, and the nodules are much smaller and less 

 prominent. Two specimens found by Dr. Hungerford, the most 

 perfect of which is now in the collection of Mr. James J. MacAndrew. 



Cancellaria fusca, n. sp. (Plate XXVIII. fig. 12.) 



Testa elongata, utrinque acuminata, solidiuscula, fusca, spira tur- 

 rila, gradata ; anfractus 7, sutura excavata divisi, primi 2 {em- 

 bryonales) IcBves, sequentes leviter convexi, spiraliter Jilo striati, 

 longitudina liter costati, costis rotundatis, subcrenulatis, superne 

 angulato-productis ; anfractus ultimus svperne angulatus, ad 

 unguium fascia pallida obscure cincta, supra angulum excavatus, 

 infra angulum mediocriter convexus, costis longitudinalibus circ. 

 8 munitus, basin versus attenuatus, anguste umbilicatus ; aper- 

 tura elongato-subtrigona, fauce fusca, obscure Virata; columella 

 leviter depressa, polita, oblique triplicata ; labrum arcuatum, 

 politum. 

 Long. 14, inaj. diam. 7 ; apert. long. 7, mnj. lat. 3 millim. 

 Var. minor. Testa brevior, magis inflata. 

 Long. 8, maj. diam. 5 millim. 

 Hab. Hongkong. 



This species is allied to C. costifera {^ovih.), of an almost uniform 

 brown colour, with an elevated spire and an excavated suture. The 

 longitudinal ribs are slightly nodulous or crenulated. Of the four 

 specimens in the Hungerford collection three are of the variety 

 minor. 



Calliostoma hungerfordi, n. sp. (Plate XXVIII. fig. 14.) 



Testa conica, imperforata, grisea, cceruleo-tincta, fusco sparsim, 

 maculata, ad apicem nigro-fusca, ad basin fusco triseriatim punc- 

 tata ; spira acutiuscula ; anfractus 7, sutura impressa divisi, 

 convexi, obtuse angulati, striati, spiraliter irregulariter lirati, 

 liris supremis minutissime graiiulatis ; anfr. ultimus obscure 

 biangulatus, ad basin convexus, dense spiraliter liratus, et decus- 

 satim striatus ; apertura oblique subquadrata ; columella leviter 

 obliqua, margaritacea. Operculum tenue, corneum, multispirale, 

 extus concavum. 



Alt. 24, maj. diam. 25 millim.
