128 MITRA. 



M. sciTA, Tenison-Woods. 



Shell small, ovate, shining, entirel}' pure deep brown; spire 

 obtusely rounded, apex mamillated, whorls six, smooth, tumid, 

 suture finely'- impressed ; aperture rather wide, brown within, 

 lirate, columella triplicate. Length, 8 mill. 



Tasmania. 



Very distinct from its size, and intense uniform coloring, 

 though belonging to the series of which 31. badia (= (estacea) 

 is a large representative. The above is the original description ; 

 not figured. 



M. Teresi^, Tenison-Woods, 



Shell oblong-ovate, somewhat thin, shin}', subventricose, 

 brown, with two whitish bands ; spire somewhat short, scarcely 

 acute, whorls five, smooth, tumid, shining conspicuousl}', finely' 

 canaliculate at the suture, aperture ovate, bifasciate within, 



columella triplicate. Length, 7-14 mill. 



Tamnania. 

 The coloring seems very persistent, and therefore the species 

 is not easih' mistaken. I confess, hoAvever, that if this species 

 could lose the white bands, and were to have the mouth lirate 

 within, I should regard it as a variety of M. scita. I think the 

 lira; are not persistent in the latter, and therefore the shell may 

 be the same. The above is the original description ; unfigured. 



M. TYPiiA, lleeve. PL 3t, figs. 113, 116. 



Encircled by fine stria;; horny, transparent, with a broad, 

 rusty brown band. Length, '6 inch. 



Viti Isles; I. of Bohol, Philippines, under stones at low water. 



M. peculiaris, Reeve (fig. 116), appears to be a shouldered 

 monstrosity of this species. 



M. FLEXiLABRis, Sowb. PI. 37, fig. 98. 



Smooth, with faint spiral striae ; yellow, with two orange- 

 brown bands. Length, 13 mill. 



Mauritius. 



More cylindrical and narrower than 31. typha, Reeve, and 

 differently banded, yet I doubt its distinctness from that species.
