132 THE NAUTILCS. 



CHAELES W. GEIPP. 



Mr. Charles William Gripp, of San Diego, Cal., who is known to 

 many of our readers as an indefatigable collector and generous cor- 

 respondent in exchanges of shells, died as the result of a serious 

 accident in San Diego, January 3, 1913, aged forty-eight years. 

 Mr. Gripp was a native of Odeshog, Sweden, and came to America 

 in 1875. Since 181)7 he was connected with the San Diego post- 

 oflice. Tlie funeral services were held on January Gth, and inter- 

 ment was made in the Masonic cemetery. Mr. Gripp was especially 

 interested in the Californian, and particularly the San Diego moUusk 

 fauna. He made various excursions beyond the entrance of the 

 harbor in fishing boats, and by careful attention to bottom samples 

 and stones brought up on the roots of kelp, discovered in tliis way a 

 number of new species and increased our knowledge of the old ones. 

 His collection was very complete in his specialty, and arranged and 

 labeled with that neatness and care more common with Eluropean 

 than American collectors. Personally he was agreeable, generous 

 and considerate, and will be much regretted by his correspondents. 

 He left a widow, who wa«, at the time of his death, seriously ill in a 

 hospital, thereby adding to the pathos of the circumstances under 

 which he died. W. H. D. 



NOTES. 



Cannibal Snail. — A carnivorous moUusk called Glandina was 

 imported into France from Mexico some months ago, and at a meet- 

 ing of the Academy of Sciences in Paris, Professor Bouvier asserted 

 that its cannibal propensities were conferring immense benefit on 

 market gardeners. 



Snails commit serious depredations on French cabbages and 

 salads, but since the arrival of the Glandina, which lives on snails 

 and slugs, the latter have largely decreased, and agriculturalists are 

 able to send their produce to the Halles in perfect condition. 



When the Mexican mollusk encounters a French snail, it thrusts 

 forward its head, and, penetrating to the innermost recesses of the 

 enemy's shell, devours its prey alive. The eggs of the Glandina 

 are as large as those of some birds. 



The experiments conducted with a hundred giant snails from Mex- 

 ico have proved so satisfactory that arrangements are being made to 

 supply 2000 more to the market gardeners round Paris. — Daily Mail.
