14 THE NAUTILUS. 



County, Indiana. Found only on gravel bars in swiftly running 

 water. 



Fourteen specimens were collected by tlie author in August, 1901, 

 while working for the Indiana State Geological Survey. 



The smaller of the two type specimens (figured a little enlarged 

 on pi. II) is in the Indiana State Museum, the other in the author's 

 cabinet. Soft parts in the U. S. National Museum. 



I am under obligations to Mr. C. T. Simpson for assistance in 

 preparing the description of the soft parts. 



The species is closely allied to L. leptodan Raf., particularly in its 

 anatomical characteristics ; the shell differs from that species by not 

 having the wing and by the posterior end being rounded and in ihr 

 full-grown shell being not more than onH-h;iif tlie size. 



The two small shells found at Hardy. Ark., by Mr, J. H. Ferriss, 

 by him referred to L. siwpsnni (Nai Tin s, Aug., 1900, page 39), 

 are without doubt this species. 



Mr. C. T. Simpson informs me ihat Mr. Paul Bartsch of the 

 National Museum believes he has found the same species in tie 

 Iowa River at Iowa City, Iowa. 



I take pieasiu'e in naming this species in honor of Prof. W. S. 

 Blatchlev, State Geologist of Indiana. 



NEW ENGLAND MARINE COLLECTING. 



BY RKV. HENHY W. WlNKI.KY 



Occasional letters ask the following ([uestioiis : " Can I stork up 

 duplicates by a week or two in New Engbind ? Where is the best 

 place to collect?" An answer to all may be made by narrating my 

 own experience. During fifteen years I have devoted much time to 

 collecting. Considerable dredging has been done, but not below 

 2.5 fathoms. The most careful searching has been done at Eastport, 

 Wiscasset, Casco Bay and Old Orchard, Maine, and Wood's Iloll, 

 Mass. Other places have had some visits. This area contains per- 

 haps 250 shell-bearing mollusca ; of these I have 200 and lack 50. 

 Of the 200 found l)y me, 113 species I have only for my own cab- 

 inet, 12 more I have spared for exchange perhajis once, and 20 more 

 have yielded a few exchanges. This leaves 55 species that I liave 

 had in quantity.
