PEBISTERNIA. 85 



Not unlike P. ustulata, Rve., and may be only a large variety 

 of it. 



P. DESPECTA, A. Ad. PI. 66, figs. 91, 98. 



Yellowish or reddish brown, ornamented with white spiral 

 lirse, base of canal dark chocolate. Length, '8-1 inch. 



China ; New Zealand. 



P. Zealandica, A. Ad. (fig. 98), is somewhat more slim, the 

 spire more produced than the type, but is otherwise indistin- 

 guishable. 



P. SQUAMOSA, Pease. PI. 66, fig. 99. 



Orange-yellow, nearly white at the base of the shell and beneath 

 the sutures where the ribs become spinose ; light roseate within 



the aperture. Length, 1*25 inches. 



Baker's Island. 



P. ROLLANDI, Bernardi. PI. 66, fig. 100. 



Light orange-colored, yellowish within. Length, 41 mill. 



New Caledonia. 



Kobelt compares this to P. Caledonica, Petit (= ustulata, 

 Rve.), and suggests that it may prove to be a large, old speci- 

 men of that species ; it is very probable, although the figure and 

 description do not indicate the dark base characteristic of P. 

 ustulata. The figure reminds one of a Coralliophila. 



P. NASSOIDES, Reeve. PI. 66, fig. 101. 



Yellowish brown, with a central white band ; apex and aper- 

 ture rosy. Length, 1*5 inches. 



Isl. of Ticao, Philippines ; upon coral reefs. Cuming. 



The plications of the columella are obsolete, so that it is very 

 doubtful whether this is a true Peristernia. Reeve and Kobelt 

 are both uncertain as to its generic position. I have seen no 

 specimen, and therefore leave the shell where my predecessors, 

 in the exercise of their best judgment, have placed it. Is it per- 

 chance a Hindsia ? 



P. SCABEA, Souv. PI. 66, fig. 102. 



Chocolate-brown, lighter on the ribs. Length, 15 mill. 



New Caledonia.
