Mr. T. Tatum on new species of Coleopterous Insects, 49 



Addendum to the Paper on the Classification of the British Marine 

 Testaceous Mollusca, ' Annals/ vol. vii. p. 469. 



Exmouth, June 19, 1851. 

 In the postscript to this paper, I stated twR the foot of the 

 Conovulus denticulatus was entire, and beyond doubt it breathed 

 free air, and that the species usually called the C. bidentatus or 

 albus had the foot divided transversely, and I considered it a 

 Pedipes, and probably a pulmonifer. Since the above was writ- 

 ten, I have decisively verified the last condition, and for the third 

 time, the transverse scission of the foot. The Conovuli may 

 therefore be regarded as established pulmonifers, and probably 

 hermaphrodites with mutual congression : perhaps the better 

 term for the respiratory qualities of this family and the Limneadae 

 would be pulmonibranchiates. Their position in my classifica- 

 tion remains the same. I beg that Qarychium may be added to 

 the Conovulidan family, and, for the present at least, be regarded 

 as a dioecious pulmonifer. Its position in the diagram of genera 

 requires no change — it is only to be deemed a Conovulidan. 

 With respect to Acme I have greater difficulty; the animal 

 requires further investigation. I would be greatly obliged for 

 some examples, sent in a half-pint bottle, in fine moss, well 

 saturated, guarded by a wooden case, per post — moss in such a 

 sized bottle would for a sufficient period escape exsiccation. 



As to Cyclostoma, though much more allied in structure to 

 the Paludina and Littorince than to the free air-breathing 

 animals, it may be more correct to term it a pulmonifer terres- 

 tris — W. C.
