My largest specimen measures three quarters of an inch in 
length. Humbleton quarry and Tunstall Hill. 
Loxonema rugifera, Pliill. Humbleton quarry and Tunstall 
Hill. 
Loxonema fas data, n. sp. 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 syg- 
moid. In form, it resembles the Turritella Urei, with which 
I formerly identified it. Humbleton, Tunstall Hill, Hawthorn 
Hive, and South wick-lane House. 
Turbo Afancuniensis, Brown. Tunstall Hill. 
Turbo Tunstallensis , n. sp. Resembling the last, but with 
rather more tumid whorls, less prominent ridges, and a 
shorter spire. Tunstall Hill. 
Turbo Permianus , n. sp. “ Spires 4, smooth, length under 
a quarter of an inch ; Hawthorn Hive. (M. S. Catalogue 
of fossils by Mr. Phillips of York),” cited by Sedgwick in 
Geol. Soc., 2nd s., vol. III., p. IS. 
Turbo Thomsonianus, n. sp. This species resembles T 
Mancuniensis in form, but its whorls are furnished with nu¬ 
merous spiral threads. It is marked with transverse coloured 
bands. Tunstall. 
Nalica Leibnitziana, n. sp. In this species the whorls 
increase rapidly in size, and are marked with zig-zag coloured 
bands: it has a flattened spire, and a slightly spreading inner 
lip. Tunstall Hill and Silksworth. 
Pleurotomaria Permiana , n. sp. This species resembles 
the P. carina/a of J. Sowerby, with which 1 formerly iden¬ 
tified it, but it has a concave sinual band, and a smaller 
umbilicus: its coloration consists of straight, and not zig-zag 
longitudinal bands as in the latter : it is spirally threaded, and 
its pillar lip is perpendicular. Rather common. 
Pleurotomaria nodulosa, n. sp. Spirally threaded, the 
threads crossed with rather strong lines of growth : with two 
spiral rows of tubercles, one situated immediately below the 
sinual band, and the other close to the suture: the sinual band 
is concave, and furnished with a mesial thread. Rather rare.
