80 PERISTERNIA. 



I suspect that this is merel}^ a rather slim specimen of P. 

 Philherti^ which is itself, possibly a mere variety of P. nassa- 

 tula, Lam. 



P. NASSATULA, Lam. PI. 64, figs. 44-4ii, 51, 52, 58. 



Light yellowish-brown, deeper in the interstices of the ribs; 

 aperture light purple. Length, 1-1-75 inches. 



Red Sea ; Indian Ocean; Philippines; New Guinea; 



New Caledonia ; Paumotus. 



P. sub-nassatula, Souverb. (fig. 52), is founded on a single 

 specimen in which the ribs are undeveloped ; it is from New 

 Caledonia. P. Deshayesii^ Kobelt (fig. 4'7), is a small form, 

 without sufflcient permanence to constitute a variety. P. Fors- 

 fcalii^ Tapparone (fig. 51), is a long, slim form from the Red 

 Sea, which may be separated as a variety. P. microstoma, 

 Kobelt (fig. 58), from Mauritius, is the same. 



P. Wagneri, Anton. PI. 64, figs. 59-62. 



White or yellowish, interruptedly marked with chestnut spots 

 between the ribs, forming three revolving rows of maculations ; 

 aperture white within. Length, 1-1-5 iuches. 



Viti Islands — Garrett. 



This unfortunate shell, misunderstood by Reeve and others, is 

 certainly quite distinct from the species with which it has been 

 confounded. I figure Turhinella craticulata^ Wagner (not Lam.), 

 upon which Anton founded the name (fig. 62) ; also T. crenulafa, 

 Reeve, not Kiener (fig. 61), Purpura Bucciniformis , Kiener 

 (fig. 59), and T. tigrina, Hombr. et Jacq. (fig. 60), the latter 

 being a young shell. 



P. SPINOSA, Martyn. PI. 64, figs. 48-50. 



Body-whorl biangulate, and spinose on the angles ; white, 

 banded, especiall}^ on the lower part, with chestnut or chocolate ; 

 aperture light purple. Length, 1-1-5 inches. 



Viti and Friendly Islands. 



P. ioHtoma, Xuttall (but never described b}' him), is figured in 

 Kiister's monograph, and referred to the coast of California. 

 The figure (fig. 50) represents very fairly a P. sjnnosa, and the 

 locality is, of course, erroneous.
