West Cliff, Colorado, Dec. 7, 1889. 
Hyawrnta Srerkit Dall, originally found near New Philadelphia 
(Tuscarawas Co.), Ohio, has also been collected in the Northeast 
(either Summit or Lake Co.) of the same state-—Dr. Sterki. 
For THE EXAMINATION of small and minute species of Hyalinia, 
Pupa, Vertigo, etc., it is just the right thing to have everything 
collected in a locality mixed up; that will allow the best idea of the 
malacological character of a place—Dr. Sterki. 
Pura Hotztncert, Sterki, proves to be widely distributed in the 
Northwest. Since the first few examples were known it has been 
collected in Will and LaSalle Counties, Illinois, by Mr. J. H. Ferriss, 
of Joliet, Il. From Iowa, Nebraska and Dakota (Ft. Berthold), 
I found it in collections, under various names. From Minnesota I 
know of none after the first examples from Winona.—Dr. Sterki. 
Dr. Dawu has recently proposed a new classification of the 
Bivalves, very different in some respects from the old arrangements 
founded on the number of muscles or gills. An abstract will appear 
in the January NAUTILUS. 
AN INTERESTING little book has been received from Prof. R. E. 
C. Stearns, on “ Ethno-Conchology ; a study of Primitive money ” 
(Ex Rep. U.S. Nat. Mus.). Romance and love, pearls, treasures, 
dashing Spanish cavaliers, and all manner of attractive things illu- 
minate the earlier pages; from these the author descends to the 
more sordid and commonplace money-cowries, and to strings of 
purple and white wampum, Dentalium-money and Haliotis-money. 
It is all so interesting that we will not quote, but recommend the 
entire paper to our readers.
