] Gabriel, Exotic Mollusca found at Coode Island. C)j 



riisHca, Linn., suggested South African material, while North 

 America was denoted by the finding of the large Nassa 

 fossata, Gould, and Crncibuhtju sbinositm, Sow., which appeared 

 in great quantity. Possibly with further search more species 

 could be obtained. 



Since two faunas widely separated are represented at this 

 locality, it is, I think, of paramount importance that a list be 

 made and recorded. Of the total, go species have been 

 identified, the remaining being in too indifferent a condition 

 for certain identification. However, where possible the genus 

 is given. It is interesting to observe that the South African 

 representatives on this occasion are in many instances identical 

 with specimens obtained in the Durban ballast of 1900, a dray- 

 load of which was carefully worked over by our fellow-member, 

 Mr. J. H. Gatliff. 



The identification of material such as this, and especially 

 when in bad condition, is no easy task, and I have to acknow- 

 ledge great assistance from Mr. Gatlii^'s labours. The North 

 American species were identified by comparison with specimens 

 received from a Calif ornian correspondent. With this evidence 

 I venture to suggest , that these are the localities for our Coode 

 Island foreigners. 



My note is somewhat brief, its object being merely to place 

 on record the existence of these exotic shells on the island. 

 As a Club we have to thank Mr. Tovey for bringing this 

 matter under our notice, and I think some satisfaction is 

 gained in the fact that by so doing we bequeath a help to 

 subsequent workers, in whatever branch of natural history 

 they may be concerned.
