86 PERISTERNIA. 



Only a single specimen known, which is in the Bordeaux 

 Museum. 



P. NoxiMEENSfs, Crosse. PL 66, fig. 103. 



Ashy, with three orange-colored bands ; purplish within. 



Length, 11/5 mill. 



New Caledonia. 



This shell is so close to the preceding, that I have very little 

 doubt that thej^ will prove to be identical. 



P. FUSCOZONATA, Angas PI. 66, fig. 104. 



White, with a more or less interrupted, broad, brown band on 

 the periphery appearing above the sutures on the spiral whorls. 



Length, 14 mill. 



So. Australia. 



Described as a Siphonalia because there are no distinct plaits 

 on the columella, but I think that Kobelt is correct in referring 

 it to the Peristerniinae. It looks something like a young Triton 

 chlorostoma, Lam. 



P. GIBBA, Pease. PL 68, fig. 143. 



Ribs white, interstices pale purple-violet, sometimes iridescent ; 

 aperture deep violet. Length, 13 mill. 



, Howland Isl. 



An aberrant form, quite distinct. 



P. GRANULOSA, Pease. PI, 66, fig. 105. 



Shell elongately fusiform, longitudinally ribbed, ribs nine, 

 rounded, corded with transverse ridges, with a small granose 

 ridge encircling the interstices ; whorls angulated and slightly 

 excavated at the upper part, angulation encircled by close-set 

 granulose ridges ; outer lip lirate within ; whorls convexly 

 rounded ; color reddish-brown, granules lighter, aperture violet. 



Length, 22 mill. 



Paumotus Is. 



Undetermined Species. 



P. CALIFORNIA, A. Ad. In H. & A. Adams' Genera. I have not 

 found the description of this species. 



P. FENESTRATA, Gould. A young shell 13 mill, in length. Not 

 figured. 



St. Simon's Bay, Gape of Good Hope. 

 There is a Turbinella fenestrata, Anton also undetermined.
