»b 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 thej^ will prove to be identical. 



P. FUScozoNATA, Angas PL 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 Siphonalm because there are no distinct plaits 

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

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

 chlorostoma, Lam. 



P. GiBBA, Pease. PL 68, fig. 14.3. 



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



aperture deep violet. Length, 13 mill. 



Howland hi. 

 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 II. & 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.
