350 MOLLUSCA. 
Fam. VERONICELLID. 
No shell. Mantle extending over the whole length of the body and considerably 
overlapping the foot at the sides, coriaceous. Pulmonary and anal orifices at the 
hinder end of the body, almost median, but a little to the right side. Lower feelers 
bifid. Jaw arched, ribbed. Teeth of the radula subquadrate ; median narrow, one- 
cusped; laterals also one-cusped, rather blunt. 
VERONICELLA. 
Veronicella, Blainville, Journ. de Physique, 1817, p. 440, t. 2. figg. vi. 1, 2 (copied in Férussac’s 
Hist. Nat. Moll. Terr. t. 7. figg. 6, 7); Stoliczka, Journ. Asiat. Soc. xlii. 2, p. 33 (1872) ; 
Binney, Land and Freshw. Shells N. Am. i. p. 303; Man. Am. Land-Shells, p. 414. 
Vaginulus, Férussac, Tabl. Syst. Moll., Prodr. p. 13 (1821) (first reliable description) ; Pfeffer, in 
Strebel’s Beitr. Mex. Land- und Sussw.-Conch. v. p. 126. 
Vaginula (Fér.), Fischer & Crosse, Miss. Scient. Mex., Mollusca, i. p. 671. 
Breadth of the animal considerably exceeding the height; fore and hind extremity rounded. 
Circumtropical, extending northward to San Francisco (California) and Florida, 
southward to Chile, Buenos Ayres, Natal, and Queensland. 
Blainville’s description is erroneous in one point, the pretended rudimentary shell, 
but all the rest is correct, even to the position of the pulmonary orifice, and his figures 
clearly show what genus is meant. The species can scarcely be distinguished without 
anatomical examination; but as I have no opportunity to do this, I merely describe 
the sculpture and colour of the mantle and the size of the body in each species, in the 
author’s own words.
