marine British Shells and Animes: 195 
the class Zoophyta, of which I have already been favoured with a 
few of a very interesting nature, either entirely new, or not 
described as British. 
TURBO DISPAR. 
Tas. XIII. Fig. 4. 
Shell strong, short, conic, of a blueish-gray colour, with four 
spires; the lower volution is very large, obsoletely striated in a 
spiral direction, wrinkled obliquely, and sub-carinated at the 
base; the superior volutions are very small, making together 
about one-fourth the length of the shell, and are usually decor- - 
ticated: aperture sub-orbicular, within of a dark purple, with 
one pale band near the lower extremity ; inner lip spreading. 
Length a quarter of an inch; breadth very little less. 
This species bas somewhat the habit of Turbo ziczac, but is 
proportionally shorter, more obtuse, has a greater disproportion 
between the body and superior volutions, and does not possess 
the zigzag markings usually attendant on that shell, nor the two 
"pale bands generally exhibited within the aperture, but inva- 
riably one only. ‘The operculum is corneous, and of a dusky co- 
lour, and was attached to all the specimens examined ; an indu- 
bitable evidence of a living shell, or of containing the animal. 
I was favoured with a few specimens of this shell from the 
Rev. Mr. Bingley, who found them at Poole. 
PATELLA DISTORTA.- 
Tas. XIII. Fig. 5. 
Shell rugged and distorted, without regularity; rather is 
pressed, with an irregular margin, and very small papillaeform 
vertex, not central: the inside is not glossy, but vr through 
a lens to be minutely granulate.
