58 SUPPLEMENT TO THE CRAG MOLLUSCA. 
Scanaria Turtont, Zurton. Supplement, Tab. IV, fig. 7. 
TurBo Turtonts, Turt. Conch. Dict., p. 208, fig. 97, 1819. 
ScaLaria Turtonis, Ford. and Hanl. Brit. Moll., vol. iii, p. 204, pl. Ixx, figs. 1, 2. 
Localities. Chillesford Bed, Sudbourn Church Walks, and Beccles Waterworks. 
The above figure represents a specimen obtained by Mr. A. Bell from Sudbourn 
Church Walks, and I have very recently found another specimen at the same locality. M. 
Weinkauff (‘ Conch. des Mittel,’ vol. ii, p. 234) gives two varieties of this species. One 
he calls gracillissima. Our fossil is the less elongated one, and corresponds with the 
variety from the Irish seas; it has a deep suture, and the whorls are nearly circular. 
Scalaria trinacria, Phil., vol. ii, p. 145, looks like, and is probably a short variety of 
this species. Mr. Crowfoot sent me a fragment obtained from the Waterworks Well at 
Beccles, which pierced probably the Chillesford bed ; and this fragment I think may be 
referred to the above-named species. Fig. 5, Tab. IV, represents the portion of a shell 
also obtained by Mr. Bell from the bed at Sudbourn Church Walks, which I believe is a 
variety of the above species. It has a faint spiral ridge at the base of the volution, similar to 
that upon Se. pseudo-scalaris, Risso. I have therefore called it var. pseudo-Turtoni. In 
the ‘Ann. and Nat. Mag. Hist.,’ September, 1870, Mr. Bell gives the name of Sc. pseudo- 
scalaris from the same deposit. I have not seen that species as a British fossil ; probably 
the specimen I have figured as var. pseudo-Turtoni may be that on which he has made 
this reference. Scalaria fimbriosa is given in the list of Mr. Prestwich’s paper as from 
the Red Crag of Woodbridge. This is probably through some mistake. Scalaria com- 
munis 18 also there given from Waldringfield, but I have seen nothing answering to this 
species or I would have had it figured. 
Scataria TREeveLyaNa, Leach. Crag Moll., vol. i, p. 94, Tab. VIII, fig. 20, and 
Supplement Tab. IV, fig. 6. 
Localities. Red Crag, Sutton. Fluvio-marine Crag, Bramerton. Chillesford Bed, 
Aldeby. Middle Glacial, Hopton and Billockby. 
I have here given a large representation of a small specimen from Aldeby, found by 
Messrs. Crowfoot and Dowson. ‘This young specimen has the three upper volutions free 
from ribs of any kind, The specimen I previously figured has lost the upper half in 
which this character is shown. I have not met with this species from any other locality 
of the Chillesford bed, and it is rare in the Fluvio-marme Crag. A fragment consisting 
of a single whorl has occurred in the Middle Glacial of Hopton, and another rather more 
complete at Billockby.
