EASTERN PROVINCE SOUTHERN REGION SPECIES. 429 



2G. The jaw, however, luis no appearance of the "brace"-like ribs 

 described in that species by Sordelli (Atti Soc. Ital. Sc. ISTat., XIII, 

 3870, 49, PUite I, Fig. 25). The ribs are quite like those figured of 

 Microphysa Lansingi, q. r., altliou^h they are narrower. 



€<Ecitianella stciciila, irfi.LER. 



Shell cylindrically fusiibini, needle-bke, attenuated towards the ob- 

 tuse apex, glassy, ijolished, white; suture narrowly margined; riG-47G. 

 whorls G to 7, flattened, the last equaling two-fifths of the 

 shell's length ; columella arcuate, narrowly and abruptly trun- 

 cated at its base; aperture narrow, lanceolate; peristome 

 simple, straight, acute. Length, 4|""" ; diameter, 1|°™. Of aper- 

 ture : Length, 2""" ; breadth, f '""'. ?niarSi^

The shell figured is from Florida (JB^rf/e^/.' in coll. A. Binney). It 

 agrees well with English specimens, so that I have no doubt of its be- 

 ing the species to which I have referred it. It is not like A. iota, of 

 Jamaica, or A. Gundlachi, of Cuba, or any West Indian species. 



Pfeiffer gives Europe and Madeira as the habitat of A. acicula. It is 

 said by Moquin-Tandon to live in the crevices of rocks and under moss 

 and dead leaves. 



(Specimens have lately been found at Princeton, N. J. doubtless im- 

 ported on plants. 



Jaw and lingual membrane: see pp. 427, 428. 



Genitalia as in Ferussacia snbcylindrica, excepting that the flagellum 

 is shorter and enters the penis sac at its apex (Lehmann). 



tlGUUS, MONTF. 



Animal heliciform, obtuse before, long and pointed behind; mantle 

 subcentral, protected by a shell ; other characters as in Orthalicus, q. v. 



Shell imperforate, solid, elongate-conic, apex acuminated, variously 

 fasciated ; whorls 7-8, the last equaling about one-third the i^lieirs 

 length ; columella constricted, distinctly truncate in adult indi\ iduals ;
