BULIMULUS. 395 



to lliuL of the UnitcMl States, but is adniitted here becunse it has actually Ijeeu 

 found in Texas. It cannot, however, be considered a species of the Texan 

 Subregion. 



More slender and elonp^ated individuals have been described under the 

 names of Ji. lAehmaid and Z'lehmamd. The former name is withdrawn in the 

 third volume of Pfeiller's Monograj)!!. An imperfect smaller specimen is de- 

 scribed as nilclinus. I do not agree with Dr. Gould in also placing B. lilacinus, 

 Rvc, in the synonymy. 



The s])ccimen fi<j;in'ed above is from Dr. Binney's collection. Fig. 335 of 

 L. & Fr.- W. Shells, I., is copied from a drawing by Mrs. Say, under which is writ- 

 ten in Mr. Say's handwriting, ^^ Bulimiis serperastrua, Mexico^ Mr. McClure.*^ 

 Tliis places the identity of the species beyond any doubt. 



In the collection of Mr. Bland is a uniformly white specimen. 



Animal not observed.

Vol. III. PI. LVIII. 



Shell subperforate, thin and strong, elongated, ovate-acuminate, smooth and 

 shining, of a bright yellowish-white color, variegated with longitudinal stripes 

 and spiral zones of dark chestnut, of various widths, none of which are constant,

 about 7, a little convex ; suture delicate; aperture rounded-ovate, a little more 

 than one third the length of the shell ; peristome acute ; columella straight, 

 widening upwards, and protecting a minute umbilical opening. Length, 25 

 mill.; diameter, 10 mill.

Key West and Lower Matacumba Key, in the Florida Subregion ; St. 

 Martha, Magdalena, and Bambo Bay, New Grenada ; Maracaibo and Porto 

 Cabello, Venezuela (cabinet of Mr. Swift). It evidently belongs to the fauna of 

 New Grenada, and it is difficult to account for its presence in the Florida Sub- 

 region. (See p. 37.) 



There is considerable confusion regarding the synonymy of this shell. An 

 immature specimen from Florida was first described by Mr. Say as Bulimus
