THE NAUTILUS. 9] 
assistant. We shall miss him with his bright and happy face and 
his pocket full of shells, and all tender our heartfelt sympathy to his 
parents and brothers. 
The appended lines are by his friend, Mr. John Ford. 
CAVES: 
Toll, toll the bell! his young heart beats no mure ; 
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 will 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.: 
This new work, of which the first one of the four parts has now 
appeared, aims to present a complete introduction, key and index 
to the genera, subgenera and species, of the Helices of the world. 
Each group, 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 Helicide, Trochomorpha really belongs to the 
Zonitide ; and it is admitted to this work only because the species 
have been generally known as “ Helix.”
