1MIASIAXKLLA. 179 



The name brevis is several times preoccupied in Phasianella. but 

 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. PL 39, figs. 97, 98. 



Shell rather large, ovate-conic, solid; whorls 5, somewhat 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 wall more or less white callus, and 

 decidedly thickened near the posterior angle ; color variable, usually 

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

 lighter shades, and flammulate with dark and light below the 

 sutures, spirally traversed by narrow hair-like lines of brown or red 

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

 dominating. Alt. 20-25 mill. 



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



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

 to be plainly shown in the figures, and difficult to make out without 

 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. fulgnrata 

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

 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 what he supposes to be 

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

 place it in the synonymy of P. variegata. Philippi gives Australia 

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

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



P. UXIFASCIALIS Kiener. PL 39, fig. 96. 



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

 formed of 5 whorls, not very convex, the last large ; aperture large, 

 <>val, somewhat angulate above; color orange-red, with a subsutural
