132 THE NAUTILUS. 



is still a very doubtful question whether the species should be 

 referred to Mesodon or Triodopsis. The form here described seems 

 to establish a slight bond with such shells as Mesodon thyroides. 

 The specimens were collected by Mr. F. A. Sampson near Hot 

 Springs, Ark. — H. A. Pilsbry. 



Snail eaters. — Reading AEr. John Ford's experience with the 

 voracious Limax agrestis (Nautilus No. 7, vol. IV) reminds me of 

 another American "Cannibal." 



While looking for Glandina truncaia (in Florida) I had occasion 

 to observe several of them cha.sing the Helix Carpenteriana, catching 

 and devouring them, shell and all, and not only one or two of them, 

 nay, five, six and more within a few minutes. In cleaning the spec- 

 imens afterward I found nine specimens of H. Carpenteriana in the 

 stomach of a single Glandina, some of the Helix yet alive. — Dr. Fr.

EDWARD RICHARDS MAYO, AGED 82 YEARS. 



Died, in Boston, Feb. 12th, of pneumonia. 



Mr. Mayo was probably the oldest student of conchology in this 

 country, being a few weeks older than his friend Dr. Wesley New- 

 comb. He was born in Roxbury, Mass., now a part of Boston. His 

 occupation was book-keeping, and the last forty years of his life 

 were spent with two firms — the great dry-goods house of A. & A. 

 Lawrence & Co., and the law office of S. W. Dexter. When a 

 young man he took up the study of shells, and his interest in them 

 continued to the last. In the halcyon days of the American clipper 

 ships and whalers, Mr. Mayo was among the first to systematically 

 purchase the shells brought as curiosities. 



He was personally acquainted with Drs. Gould, Lewis, Stimpson, 

 Anthony and other well-known conchologists, who frequently had 

 occasion to study the contents of his cabinet. He had also an 

 extensive correspondence with collectors in many countries. His 

 collection was particularly rich in foreign shells, of which he had 

 several thousand beautiful specimens. 



Mr. Mayo was a very modest man, unselfish, and to his younger 

 fellow-students a useful friend, giving freely of his extensive infor- 

 mation and of his specimens, and encouraging them in their pursuit 

 of knowledge. To many readers of the Nautilus the news of his 

 death will bring a feeling of personal loss.
