PISANTA.

Brownish black ; livid within the aperturo ; lip margin and 

 colnmella tinted with yellowish brown. Length, 40 mill. 



Hah. unkitoim. 



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

 P. marmorata^ Reeve. 



P. MACULOSA, Lam. PI. 71, ilgs. 2U(;-201). 



Olive-brown, yellowish white or liglit purple, in'ofusely strealvcd 

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

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

 Sometimes dark chocolate, witli 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. jyu^io, Ijinn., Init the type of pusio is a very different 

 shell, being the West Indian P.plumata, (xmel. = articulata^ Lam. 

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

 maculosa, but the latter is so Avell known tliat 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 beenotherwise reported from the West Indies. Buc. uEthiops, 

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



P. Janeirense, Phil. PI. 71, fig. 210. 



Fusiform, solid, transversely obsoletely Urate; dark brown, 

 longitudinallj^ flecked with white, with a brown articulated white 



revolving band. Length, 1"5 inch. 



Jlio J<meiro, 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. PI. 71, 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. Lengtii, 1 to 1'25 inches. 



Loo Choo Is. 

 Reeve described this peculiar, thick shell without locality, and 

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