Man and Mollusks 5 



Indo-Pacific are the cone shells {Conns), the sting of which is as powerful as 

 the bite of a rattlesnake. Although the beautiful cone shells are among the 

 commonest of Indo-Pacific mollusks, the total number of authentic cases of 

 death from their sting is surprisingly small. No American species have been 

 recorded as harmful to man but, because all cones possess the necessary 

 apparatus, it would be wise to be careful in handling American specimens 

 over two inches in size. 



The number of cone stings is few because of the shy nature of the ani- 

 mal. Invariably a snail will withdraw into its shell when disturbed and, unless 

 the cone is held quietly in the palm of the hand for some minutes, there is 

 little likelihood of the collector being stung. The apparatus for the injection 

 of the venom into the skin of the victim is contained in the head of the 

 animal. Bite, rather than sting, is perhaps more descriptive of the operation. 

 The long, fleshy proboscis or snout is extended from the head and jabbed 

 against the skin. Within this tube are a number of hard, hollow stingers, as 

 long and slender as needles. These are actually modified radular teeth, com- 

 monly used in other snails to rasp their food. Under a high-powered lens the 

 teeth of the cone shell resemble miniature harpoons. As the teeth are thrust 

 into the skin, a highly toxic venom flows from a large poison gland located 

 farther back in the head, out through the mouth, and into the wound through 

 the hollow tube of the tooth. In some cases, death has taken place in four to 

 five hours after the patient was stung. Not all cases are serious. Andrew 

 Garrett, a famous shell collector of the latter half of the nineteenth century, 

 reported that he was stung by a tulip cone that caused a "sharp pain not un- 

 like the sting of a wasp." 



While in recent years the cone shells have received perhaps an undue 

 amount of notoriety as dangerous creatures, they are best known as an aris- 

 tocratic family of beautiful shells which have been favorites for years among 

 the most discriminating of collectors. For hundreds of years the sound of the 

 auctioneer's gavel has been heard at the sale of valuable collections of sea- 

 shells, but no shell has created such fevered interest as the Glory-of-the-Seas 

 cone. Its present-day value is in the neighborhood of $400 to $600. This 

 species seems to possess the ideal combination of features which brings high 

 prices — beauty, size, rarity and, above all, mystery or legend. Although the 

 legends connected with the Glory-of-the-Seas are for the most part untrue, 

 the mere mention of its name will invariably cause the blood pressure of shell 

 collectors to rise. 



The first published reference to the Glory-of-the-Seas was in 1757. 

 Today the whereabouts of each of the twenty-three specimens is known. 

 The most famous finding was made by the renowned shell collector, Hugh 

 Cuming, in 1838 when he found three specimens at low tide on the reefs at 

 Jacna on Bohol Island in the Philippines. The myth has often been repeated
