has tlie mantle distinctly bifid anteriorl}', — a very interesting mal- 

 formation which I have not before seen. 



T. D. A. COCKERELL. 



West Cliff, Colorado, Dec. 7, 1889. 



Hyalinia Sterkii 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 examixatiox of small and minute species of Hyallnia, 

 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. 



Pupa Holzingeri, Sterki, proves to be widely distributed in the 

 Northw'est. Since the first few examples were known it has been 

 collected in Will and LaSalle Counties, Illinois, by Mr. J. H. Ferriss, 

 of Joliet, 111. 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. Dall 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. JNIus.). Romance and love, pearls, treasui-es, 

 da.shing 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.
