Toll, toll the bell I his young heart beats no more ; 



His eyes are dimmed, his life's short cycle run. 

 No more may Science yield him, as before, 



The charming favors he so fairly won. 



Alas, that in the East his sun should set, 



And 'neath the shadows hide the hopes he knew ! 



Bright hopes, recalled to mind with keen regret 

 By all who felt his power to wnll and do. 



Though now in sorrow we must say " Farewell ! " 

 Sweet memories of him our hearts will hold ; 



While through the years that Time for us may tell 

 His friendship shall be cherished as of old. 



A NEW HAND-BOOK OF THE HELICES, i 



This new work, of which the first one of the four parts has now 

 i\ppeared, aims to present a complete introduction, key and index 

 to the genera, subgenera and species, of the Helices of the world. 

 Each grou]), whether generic, subgeneric or sectional, is defined, and 

 its species enumerated ; the type and usually a number of prominent 

 species of each is figured, and the anatomy is described and figured. 



The first genus included in the " part " just issued, is Trochomor- 

 pha, an important Asiatic and Polynesian group, many specimens 

 of which are in most collections. Although it has generally been 

 associated with the Helicidte, Trochomorpha really belongs to the 

 Zonitidte ; and it is admitted to this work only because the species 

 have been generally known as " Helix. ^'
