SUPPLEMENT TO THE CRAG MOLLUSCA. 



Tellina pulciiella ? Lamarck. Supplement, Tab. X, fig. 5. 

 Locality. Cor, Crag, Sutton. 



An imperfect valve belonging to the genus Tellina was found by myself as above, and 

 it had for some time been in my cabinet. This specimen, which is the right valve, has 

 only the anterior portion remaining, the siphonal side of the shell, which would best assist 

 in its determination, being unfortunately wanting. My specimen, however, shows that 

 the hinge possessed two cardinal teeth, one single and the other bifid, and one elongated 

 lateral tooth on the broader or anterior side resembling in its dental formula the hinge of 

 Tellina donacina, but the present specimen is much larger than any specimen of that 

 species that I have seen, and it is also a flatter shell ; like it, however, it is covered with 

 broad and distinct stria? or lines of growth. I have given it provisionally the above name. 

 Since the specimen was engraved, and while in the hands of the engraver, it has, I regret 

 to say, been destroyed. 



Tellina compressa, Broc. Crag Moll., vol. ii, p. 234, Tab. XXII, fig. 6 (as T. 



donacella). 



Locality. Cor. Crag, Sutton. 



This is an exceedingly rare shell to my researches. In the ' Crag Moll.' I observed 

 that this might probably be referred to T. compressa, Broc, of which a very bad repre- 

 sentation is given in ' Conch. Foss. Subap.,' pi. xil, fig. 9. It is the same as T. distorta, 

 Dubois, 'Volh. Pod./ Tab. V, figs. 3, 4. Mr. Jeffreys has obligingly sent me some 

 recent specimens from the Coast of Portugal with the name of Tellina compressa, Broc, 

 for comparison, and these correspond with my Crag shell. 



Tellina fabula, Gronov. Crag Moll., vol. ii, p. 232, Tab. XXI, fig. 3. 



Localities. Fluvio-marine Crag, Bramerton and Bulchamp. Chillesford bed, 

 Aldeby and Horstead. 



In the ' Crag Moll.' this shell was figured from a recent specimen, the only Crag one 

 then known having been lost. A specimen has lately been obtained from the Fluvio- 

 marine Crag at Bramerton by Mr. Reeve ; one was sent to me from Aldeby by Messrs. 

 Crowfoot and Dowson, and two were obtained by myself from Horstead.
