414 A MANUAL OF AMERICAN LAND SHELLS. 



It is a strictly Southern Eegion species, observed as yet only in 

 Florida and Georgia. 



Whitish; eyes, tentacula, and a line passing from the eyes, disap- 

 pearing uuder the shell, black ; a gamboge-colored vitta is visible 

 through that part of the shell which is opposed to the moutli. At 

 Saint Augustine I found specimens copulating in December. 



Jaw as usual ; no anterior ribs. 



The lingual membrane (Terr. Moll., V, Plate X, Fig. O) has 18-1-18 

 teeth, with about 10 perfect laterals. Morse gives 50 rows of 30-1-30 

 teeth. The central tooth has a peculiarly narrow base of attachment 

 and a very greatly developed median cusp, the side cusps being sub- 

 obsolete. 



Genitalia as in S. ohliqua {q. v.). 



Family VERONTCELLID^. 



VERONICEL.L.A, Blainville. 



Animal limaciform (see Fig. 492). Body oblong-oval when contracted, 

 more or less linear when extended ; mantle covering the whole body ; 

 foot narrow, wrinkled transversely as if composed of numerous rings, 

 simple posteriorly; head distinct and capable of being retracted under 

 the mantle; buccal mass with a jaw and with papillae arranged around 

 the mouth ; tentacles two, bifid, unequal, contractile; eye-peduncles long 

 and slender, annulated, obtuse and oculiferous at tip. Pulmonary cav- 

 ity on the right side, at about two-fifths the length of the animal, and 

 opening, by means of a tube running along the side, at the posterior 

 extremity, between the mantle and the free point of the foot, in com- 

 pany with the anal opening. Organs of generation separate and dis- 

 tant, the male organ protruding at the base of the right tentacle; the 

 female opening about the middle of the right side. Mucus pore none. 

 No distinct locomotive disk, though by the wide overlapping of the 

 mantle the whole base of the animal is tripartite. 



Shell non(;. 



There are but few known species of this genus, found in South 

 America, the Philippines, South Africa, and the West Indies and Mex- 

 ico (whence it ranges into Southern California). Our single Florida 

 species belongs rather to the fauna of tropical than ]N"orth America. 



The name Vaginula, sometimes used for the genus, was published 

 several years after Veronicella ; it is now ai)plied to an agnalhous 

 genus resembling outwardly Veronicella (Stolicska, Journ. Asiatic Soc. 

 of Bengal, n. s., XLII, Part II, pp. 33-37).
