TURBO. 359 
three tuberculated spirals, one on the posterior margin, and one on each of the 
carine ; the tubercles of the first and second spiral are connected across the 
sloping part of the whorl by axial coste. Base rather inclined to be flat, and 
ornamented with four spirals which are finely granulated, except the last, 
surrounding the circular margin of the umbilicus, where the tuberculations are 
again larger. The umbilicus is rather wide, and the aperture inclined to be 
circular, but the indications are not clear. 
Apparently related to the more depressed section of M. Lyelli, but differing 
considerably in the ornamentation and shape of the whorls. There is one specimen 
in the Sharp Collection at the British Museum, most probably from Ponton or 
Barnack. A second specimen in my own Collection already shows some difference. 
No others have come under my notice. 
294. Turso “spatTHica.” Plate XXX, fig. 5. 
Description : 
Height ; ; : ; . 45 mm. 
Width 6 : - omm. 
Shell conical, umbilicated, spire elevated, apex obtuse, number of whorls five. 
Toacertain extent this form reminds one of Turbo delphinuloides, V Arch. (op. cit., 
p-. 379, pl. xxix, figs. 3a@—c). Ours is a smaller and more conical shell than 
d’Archiac’s species, but the angular character of the whorls and the thick radial 
cost are points of resemblance. The base is rounded and smooth (radial lines 
alone being visible)—a feature which at once separates M. ‘ spathica”’ from 
M, Lyelli and its relatives. 
Two specimens are known to me, both being from the Lincolnshire Limestone, 
precise locality unknown—probably Ponton, Barnack, or Weldon.
