86 PERISTERNIA. 



Only a single specimen known, which is in the Bordeaux 

 Museum. 



P. NOUMEENSIS, Crosse. PI. 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 they 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. PI. 68, fig. 143. 



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



aperture deep violet. Length, 1.3 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. CALIFORNICA, 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, Cape of Good Hope. 

 There is a Turbinella fenestrata, Anton also undetermined.
