Contains a general description of shell and animal, and the following 
systematical arrangement into four genera : — 
Fam. Coecidoz : testa nucleosa spiralis, postea tubularis, regularis, baud 
affixa ; apertura orbiculari ; operculum corneum, multispirale, 
margine baud fimbriato. 
1. Gen. CcBcum (Flem.): Testa nucleosa planata ; animal una in plana 
solute orbiculari crescens [the author’s meaning is that the young 
shell grows in a spiral which lies in one plane, and the whorls of 
which are detached one from the other] ; testa animali crescente 
iterum iterumque decollata ; septo regulari, varie constructo, 
partem decollatam tegente ; superficie seu annulata, seu lirata, seu 
Igevi ; apertura plerumque primum constricta, posted expansa | 
operculum concavum seu subplanatum, sutura ssepius linea elevata 
instructa, interdum laevi. 
Sects. 1, Laevia ; 2, Annulata; 3, Costulata ; .4, Quadrilata; 
5, Armata. 
2. Gen. Mioceras (Carp.) : Testa adolescens solute 'spiralis baud 
planata ; adulta saepe inflata. Apertura obliqua ; operculum spi- 
rale, extus concavum, anfractibus linea spirali instructis. [The 
shell resembles the shape of^ the horn of an ox ; all species are 
smooth.] 
3. Gen. Strehloceras (Carp.) : Testa baud decollata ; vertice nucleoso 
orbiculari, planae tuberculari perpendiculariter affixo. Habitus 
increscentis plerumque orbicularis seu subtortuosus. [Nucleus 
permanent, and lying in a plane perpendicular to that of the fol- 
lowing parts of the shell. All the species fossil.] 
4. Gen. Parastrophia (Folin), olim Moreletia (Folin) ; Testa tubu- 
laris, elongata, basin versus inflata, baud decollata ; apice nucleoso 
subspiral i. 
The animal of all but the first unknown.
