; ADDENDUM. 175, 
Columbella scripta is given by Mr. Jeffreys in his list, to Mr. Prestwich’s Red Crag 
paper, as from Sutton, Walton, and Waldringfield, but I have not been able to confirm 
that reference. 
Lacuesis, Risso. 
This generic name ‘has been adopted by all our modern conchologists, and I have here 
employed it, but upon what special characters it is founded I do not know unless it be 
upon some peculiarity in the animal. 
The name ZLachesis is unfortunately used for a genus of Reptilia and also for a genus 
of Arachnide. The little shell Buccinum minimum, Montague, now called Lachesis, I 
have not yet seen as a fossil in England. 
Lacnesis Anetica, 4. Bell. Addendum, Plate, fig. 7. 
Locality. Cor. Crag, near Orford. 
Mr. Robert Bell has sent to me a specimen with this name attached. It has six 
volutions with a deep suture, and the last volution has about a dozen longitudinal ribs or 
coste, which are made nodulous by the crossing of three or four large spiral threads or 
ridges. The mouth is ovate and about one fourth the length of the shell, with the outer 
lip denticulated within. There are also some coarse striee below the volutions. It is the 
only specimen I have seen, and unfortunately the upper portion or apex is destroyed. 
Judging from the figure this appears to be distinct from Lachesis (Buccinum) candidis- 
sima, Phil. 
Buccinum Tomumnnt, Canham,m.s. Addendum, Plate, fig. 11. 
Locality. Red Crag, Waldringfield. 
A single specimen as represented has been sent to me with the above name by Mr. 
Canham. It was found, he tells me, in the workings for “ Coprolite,” on the ground of 
Colonel Tomline, whose name he wishes to commemorate as a friend to science, and 
a gentleman who has given him every facility for obtaining Crag specimens. 
This shell resembles B. Dale, but it differs in several particulars, so as to justify in my 
opinion a distinct specific position. It has a more elevated spire, with less tumid volu-
