PISANIA. 



P. PA/I, Crosse. PI. 71, fig. 205. 



Brownish black ; livid within the aperture ; lip margin and 

 columella tinted with yellowish brown. Length, 40 mill. 



Hob. unl.-iioii'ii. 



This species also, as well as P. cinis, Reeve, may be a form of 

 P. marmorata, Reeve. 



P. MACULOSA, Lam. PL Tl, figs. 206-209. 



Olive-brown, yellowish white or light purple, profusely streaked 

 and spotted with chestnut-brown, with frequently a light central 

 band ; interior brownish or chocolate, showing the white band. 

 Sometimes dark chocolate, with numerous white spots and band. 



Length, -75 to 1'25 inches. 



Mediterranean (littoral), Azores ; St. Croix, W. I. ? 



Fossil in several parts of Southern Europe. 



This species is known to many European naturalists under the 

 name of P. pusio, Linn., but the type of pusio is a very different 

 shell, being the West Indian P.plumata, Gmel. = articulata, Lam. 

 Gmelin has called it striata, and his name has priority over 

 maculosa, but the latter is so well known that I will not displace 

 it. Specimens in the collection of the Philadelphia Academy 

 are labelled " St. Croix, W. I., R. E. Griffith," but the species has 

 not been otherwise reported from the West Indies. Buc. JEthiops, 

 Phil. (fig. 209), is evidently a very dark, immature maculosa. 



P. JANEIRENSE, Phil. PL 11, fig. 210. 



Fusiform, solid, transversely obsoletely lirate ; dark brown, 

 longitudinally flecked with white, with a brown articulated white 



revolving band. Length, 1/5 inch. 



Rio Janeiro, Brazil. 



The greater size and solidity are the chief distinctive features ; 

 it is very likely only a finely grown P. maculosa, Lam. 



P. CINGULATA, Reeve. PL U, figs. 211, 212. 



Yellowish brown, with narrow chestnut revolving threads, 

 which are frequently interrupted, causing the coloring to appear 

 as revolving rows of spots ; light chocolate within the aperture, 



ridged. Length, 1 to 1-25 inches, 



Loo Glioo Is. 



Reeve described this peculiar, thick shell without locality, and 

 at first I was disposed to regard it as a variety of Euthria lineata,
