A MONOGRAPH OF THE GENUS 



FICULA. 



Genus. — Testa pyriformis, tenuis, fere convoluta superne 

 ventricosa, versus canalem attenuata ; spira brevissima, an- 

 fractibus depresso-cupolseformibus parvis ; apertura utrinque 

 terminalis, inargine externo tenui rotundo. Operculum 

 nullum. 



Syn. Pyrula, part. Lam. Ficus, Rousseau. 



The animal soft parts of the Ficulse are known to be quite 

 different from those of the Pyrulse nearest to them in the 

 form of the shell. The absence of an operculum is an 

 ascertained fact. The four or five species composing this 

 genus are much alike in the beautiful curves of the pyriform 

 shell. 



Species. 



1. Ficus, f. 4, Linnams. — Testa superne ventricosissiina 

 breviuscula, tenuiter et leviter striata, griseo-fulva, distant er 

 albo-fasciata, super fascias distanter nigro maculata, inter 

 fascias fusco piperita. — Shorter and more ventricose than 

 the other species, with strias so lightly impressed as to have 

 the appearance of a smooth surface. There are white bands 

 at intervals with rather large dark spots, and the surface 

 between the white bands is sprinkled with smaller spots. 

 Lamarck, finding two species referred to by Linnams under 

 the above name, chose to apply that name to the present, and 

 to give a new name to the following species. Reeve afterwards
