210 PERMIAN FOSSILS. 
Diagnosis.—“ A subulate, many-whorled, smooth species, with two or more dark 
spiral bands, crossed by others, on a light ground: its outer lip is inversely sigmoid.”? 
(King.) 
In form this species resembles the Zurritella Urei, Fleming, with which I formerly 
identified it. Zurbonilla Altenburgensis, Geinitz, of the German Zechstein, is a more 
tapering species than the present one; but both agree in the roundness of the whorls. 
Loxonema fasciata is a rather variable species, some specimens being shorter than 
others; while the number of whorls remains the same. My largest specimen is three 
eighths of an inch in length. 
It occurs in the Shell-limestone at Humbleton, Tunstall Hill, Hawthorn Hive, 
and Southwick-lane House. Professor Phillips's collection contains a specimen found 
at Ferry-bridge.

Diagnosis.—Turreted : plicated longitudinally. 
Imperfect specimens, about an inch in length, of a species resembling Lovonema 
rugifera, Phillips, have twice occurred to me ; but through some accident, they have been 
mislaid: I am therefore unable to give any other than a provisional diagnosis of it. 
Loxonema Swedenborgiana occurs in the Shell-limestone at Tunstall Hill, and Hum- 
bleton Quarry. 
LoxoNEMA GEINITZIANA, King. Plate XVI, fig. 31. 
Diagnosis.—Minute: subulate: (?) smooth: many-whorled. Aperture sub-orbi- 
cular. Whorls flatly convex. 
This species differs from Lovonema fasciata, which it otherwise resembles, in being 
smaller, and in having the whorls flatter, and the suture shallower. A specimen, 
measuring a quarter of an inch in length, has eight whorls. 
Loxonema Geinitziana is a rare fossil in the Shell-limestone at Humbleton Hill. I 
have seen a specimen which was found at Nosterfield. 
It is cited in Professor Sedgwick’s Memoir (Trans. Geol. Soc. Lond., 2d series, 
vol. iii, p. 118) from Professor Phillips’s MSS., that ‘five species of Melaniz (?) less 
than half an inch long, with eight whorls” occur at Hawthorn Hive: perhaps the 
number is overstated through some error.
