with six or eight spines, which add greatly to its beauty. In the older shells they 

 gradually disappear. 



Polystomella umbilicatula, {Macg.) A single specimen only has occurred to me in 

 the shell-sand from Falmouth. 



Polystomella Gulielmina, {Macg.) This I have named with doubt, as the shell 

 has hitherto been only described as found at Aberdeen. I found it on an oyster shell 

 dredged off St. Mawr's. 



The following shells hitherto unnoticed as found in Cornwall have occurred to me: 

 Dentalium glabrum. Shell-sand, Falmouth. 

 Pholas Candida. Penzance. 

 Solen vagina. Shell-sand, Falmouth harbour. 

 Psammobia tseniata, (Turton). Not uncommon at Falmouth. 

 * Crapina scotica. Obtained by dredging at Falmouth harbour. 

 Limnaeus glaber. Is mentioned in Mr. Couch's Fauna, on the authority of Mon- 

 tague, since whose time it has not been found in the county. I am happy to state 

 that I have found it near Probus. 



Velutina otis. Gewan's Bay, between tide-marks. It is probably common, but 

 not easily found on account of its minute size and brown colour, which afford it great 

 security from the rapacity of collectors. 



Odontomia rissoides and Odontomia turrita. Oyster shells, Falmouth. 

 Turbo terchosus. Abundant in a small spot near high- water mark in Truro river. 

 This species is viviparous. I have found the mother filled with young fry 1^ 

 whorls, April 28, 1846. 



Turbo jugosus. Is reckoned a species in Thorpe's ' British Marine Conchology,' 

 and it has not as yet been noticed as found in the county. It may therefore be im- 

 portant to state that it is common on our coasts, particularly at Cape Cornwall. 



Cingula semicostata. Of this rare species I have found a single specimen in shell- 

 sand from Whitsand Bay. — Robert L. King ; Grammar School, Truro.

All those runs where cattle or sheep are kept are generally without 

 the boundary, and a tax of £\0 is paid to government. There is al- 

 ways beautiful pasture, as besides our cattle, so poor is Australia in 

 quadrupeds, there is nothing to eat it off. This country is a most pe- 

 culiar one, differing from any other I have ever visited or read of. It 

 is covered generally with wood, though in the interior there are ex- 

 tensive grassy plains with scarce a tree upon them for miles : this 

 forest-land under certain appearances has different names. What I 

 I should term " Jungle n is here called " Bush," which signifies a 



* Since writing the above, Lucina rotundata {Turton), has occurred to me. Two 

 specimens I have found in shell-sand from Falmouth harbour. I consider it there- 

 fore a rare species on our coasts.
