PHASIANELLA. 179 



The name brevis is several times preoccupied iu Phasianella. l)ut 

 not, I believe, for well established species. However if it be deemed 

 desirable to avoid this duplication, the present species may be call- 

 ed P. brevissima. 



Subgenus Orthomesus Pilsbry, 1888. 



Shell and operculum similar to Phasianella ; radula with the cen- 

 tral tooth reduced to a minute rudiment or absent. 



Indo-Pacific Province. 

 Type, P. variegata Lam. 



P. VARIEGATA Lam., 1822. PI. 39, figs. 97, 98. 



Shell rather lai'ge, ovate-conic, solid; whorls 5, someAvhat convex, 

 separated by well marked sutures, somewhat flattened above; spire 

 pointed, conic; aperture rather small, short ovate, less than half the 

 length of shell, widely rounded below, angular above; columella 

 with a flattened callus ; parietal Avail more or less Avhite callus, and 

 decidedly thickened near the posterior angle ; color variable, usually 

 flesh tinted, ashen or broAvn, more or less clouded with darker and 

 lighter shades, and flammulate Avith dark and light beloAV the 

 sutures, spirally traversed by narrow hair-like li)ies of brown or red 

 interrupted by white dots and intervals, the Avhite sometimes pre- 

 dominating. Alt. 20-25 mill. 



Zanzibar; Bed Sea ; New Caledonia ; Mauritius, etc. 



Rather variable in coloration, but the narrow lines, — too narroAV 

 to be plainly shoAvn in the figures, and difficult to make out Avithout 

 a glass — are constant. 



The synonymy is extensive ; including P. nivosa (pi. 38, figs. 49, 

 50) P. jaspidea, (fig. 44, 36.) P. lentiginosa (fig. 51.) and P. fulgurata 

 (fig. 55) of Reeve, P. grata (pi. 39a, fig. 14), P. splendida (pi. 39rt, 

 fig. 5,) of Philippi, P. lineolata Wood, P. viridis Anton, and P. rubens 

 Lam.. The latter I cannot identify; but judging from Philippi's 

 description and figure (pi. 39a, figs. 6, 7) of Avhat he supposes to be 

 Lamarck's species, and from Kiener's, (pi. 38, figs. 47, 48) I Avould 

 place it in the synonymy of P. variegata. Philippi giA'es Australia 

 as the locality of P. rubens. P. broungniarti Audouiu, (PI. 39, figs. 

 63-66) is said to belong here. It is from the Red Sea. 



P. UNiFAsciALis Kieucr. PI. 39, fig. 96. 



Shell, oval, conic, moderately thick, spire moderately elevated, 

 formed of 5 whorls, not very coua'cx, the last large ; aperture large, 

 oval, somcAvhat angulate above; color orange-red, Avith a subsutural
