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 Turriiella Urei, Fleming, with which I formerly 

 identified it. Turbonilla Altenhurgensis, Geinitz, of the German Zechstein, is a more 

 tapering species than the present one ; but both agree in the roundness of the whorls. 



Losconema 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 Hurableton, 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 Loxonema 

 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 duarry. 



Loxonema Geinitziana, King. Plate XVI, fig. 31. 



Diagnosis. — Minute: subulate: (?) smooth : many-whorled. Aperture sub-orbi- 

 cular. Whorls flatly convex. 



This species differs from Loxonema 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 Melaniae (?) less 

 than half an inch long, with eight whorls" occur at Hawthorn Hive : perhaps the 

 number is overstated through some error.
