130 THE NAUTILUS. 



Any other Bermudian records would be gratefully received by the 

 writer, as he has in press a " Check-List of the Bermudian Mollusca." 



GENERAL NOTES. 



MOLLUSCA ON PIKE'S PEAK COLORADO Last fall I collected 

 Pupa muscorum (L.), Vallonia cyclophorella Ancey, Euconulus 

 fulvus (Miill.) and Zonitoides arboreus (Say) by the printing office 

 on Pike's Peak, 10,000 ft. alt. I put them on record because of the 

 altitude; the dominant vegetation of the place consists of Achillea, 

 Dasiphora, Fragaria, Salix, Rosa, Populus tremuloides, Oarduus, 

 Geranium, Epilobium, Delphinium, Arctostaphylos nva-ursi, Cam- 

 panula, Potentilla, Allium, Pedicularis, Gentiana, Picea, Pinus, 

 Juniperus, Antennaria, Artemisia, Pentstemon, Machaeranthera, Rud- 

 beckia, Frasera and Galochorlus : nearly all circumpolar genera, it 

 will be observed, the last five only being exclusively American. I 

 have a note that I found also Succinea avara, but kept no specimens. 



T. D. A. COCKERELL. 



CHIONE CANCELLATA LINN. IN THE JERSEY CITY MARKET. 

 A strange shell in the market always interests the conchologist. A 

 short time ago my brother gave me a Ghione cancellata which he had 

 found with some clams ( Venus mercenaria) purchased of Mr. Brittain, 

 a fish dealer on Bergen ave., Jersey City, N. J. He said there were 

 several in the basket from which the clams were taken. Desirous 

 of knowing whence they came, I inquired of Mr. Brittain where the 

 clams were gathered and he said he believed they came from North 

 Carolina SLOMAN Rous.

 lected from the under side of an old log, 12 inches in diameter and 9
