TROCHUS HELICINUS, Schl. Geinitz, Versteinerungen, p. 7, pl. iil, fig. 14 a, 6, 1848. 
Diagnosis.—Short: conical: with four tumid whorls, which are marked with five 
or more spiral line-like ridges, separated from each other at nearly equal distances.” 
The distinctive characters of this species, which rarely exceeds three eighths in 
height, and the same in width, are its tumid whorls, rather prominent spiral ridges, 
and short spire. Having seen the original of Captain Brown’s Zurbo minutus, I feel 
quite satisfied that it is the present species. 
Turbo helicinus occurs at Tunstall Hill, in Shell-limestone, and at Newtown (where 
it occurs under a stunted form) near Manchester, in the Permian Marls (Binney). 
Professor Phillips’s collection contains a specimen collected at Aldfield, in Yorkshire. 
A single specimen occurred to me in the Dogger-bank fragment of Magnesian Lime- 
stone. Geinitz states that it occurs in the Zechstein-dolomite of Gliicksbrunn ; and 
according to Credner, it is found on the Wartberg near Seebach, in Thuringia.

Diagnosis.—“ Shell ovate; body large; spire short, consisting of three ventricose 
1 «Versteinerungen,’ p. 7. The following is the original description published by Dr. Geinitz ; “ Kurz- 
kegel formig mit vier gewolbten Umgingen, an welchen sich oben eine erhabene Linie bemerkbar macht, 
unter der die letzte Windung noch gegen fiinf Linien zeigt, die ziemlieh gleich weit von einander entfernt 
hegen. Auch erscheinen zwei feinere Linien noch in der Nahe der Naht.”
