LITTORINA. 297 
Shell thick, trochiform, sub-eucycloid. Spire pointed, but with an obtuse 
apex. Whorls about six, sutures moderately wide; each whorl furnished with 
three, or more often four, granulated spiral bands, the lowest being the most 
prominent. 
The body-whorl is large relatively to the shell, and somewhat eucycloid, owing 
to the prominence of the two lowest spirals. Number of spirals in the base five ; 
axial striz moderately shown throughout. 
Aperture widely ovate, slightly flattened in front and angular at the point. 
Outer lip thin and crenulated, inner lip very callous; indications in some 
specimens of an umbilical fissure. 
Relations and Distribution—This form passes by easy stages into others 
already named. Turbo Davidsoni, Laube, may be intermediate between this and 
the species last described. In another direction Litt. Phillipsu has affinities with 
Amberleya (Turbo) Meriani (Pl. XXITI, fig. 17), but is smaller, has a wider spiral 
angle, and is less turrited. Some Yorkshire specimens seem to connect this form 
with Amberleya ornata. 
Typical specimens occur in the Grey Limestone of Cloughton Wyke and in 
the upper beds of the Lincolnshire Limestone at Weldon and Ponton ; also in the 
Humphriesianus-zone at Milborne Port. Specimens which might be referred to 
this species occur in the Dogger at Blue Wyke and in the Pea-grit at Crickley.

Fig. 15 represents a unique specimen from the Parkinsoni-zone of Bradford 
Abbas. It is characterised by the richness of its ornamentation and the width of 
the interspiral spaces or furrows. The English specimen is more conical, and has 
a smaller spiral angle; the body-whor! also is relatively shorter and more angular 
than is shown in the type figure.
