NOTE 
oe 
I invite the especial attention of Naturalists, 
Conchologists, &c,to this remarkable series of Land 
Shells, collected by me during last summer and 
full in the canyons of the Wassatch Mt’s, Utah. 
This Collecticn is certainly one of deep scien- 
tific interest and furnishes one of the best examples 
of evolution that we have evermet with, for it closely 
unites what has been considered heretofore,as five 
zood and distinct specie, 
For the purpose of showing their close relation- 
ship I have arranged them in suites to show their 
full range of variation, in form, size, sculpture and 
color. 
I offer the following testimonials from our 
highest conchologica! authorities as evidence of their 
scientific value. 
Without exception your Utah suite is the 
most interesting I ever studied, and the most in 
structive. 
W.G. Binney. 
Your suite of Utuh Helices is deeply interest- 
ing. The forms we know as strigosa, Cooperi, Idaho- 
enusis, Hemphilli and Hiydeni, are shown by num- 
crous varieties to be intimately connected. 
Tho’s. Bland. 
I have examined with care the magnificent 
suite of land shells coilected by youin Utah, and 
do not hesitate in pronouncing them the most in- 
teresting and instructive of any groupe of Helices 
that I have ever been priviliged to study.
