In conclusion, it may be of interest to refer to some of the large 

 examples of Tridacna gigas which have been recorded. 



British Miiseum specimen 

 Specimen mentioned by Linnaeus ' 

 „ ,, ,, Dillwyn^ 



Dall 3 

 ,, Fischer* 



Although the quoted size of the specimen mentioned by Dillwyn 

 seems remarkable, I should be inclined to believe it correct. The 

 relatively smaller weight in proportion to the size is not important, 

 for the specimen in the Museum, although as long as that mentioned 

 by Dall, weighs 2 1 8 lbs. less. 



Finally, I may mention that a specimen in the window of Rule's 

 Pestaurant, Maiden Lane, Covent Garden, is 40 ins. long and weighs 

 434 Ibs.^ In this instance also, the weight, in proportion to the size, 

 is much greater than that of the Museum specimen.
