THE NAUTILUS. 87 



Mr. Wright with the remark that " they would hardly pass for typi- 

 cal Dot'mani" he at first thought they would, but further examina- 

 tion convinced him that their peculiar markings were constant and 

 quite striking. He is certainly mistaken in saying that they are 

 always a pure white shell and entirely spotless. Many that we have 

 found are prettily marked with three bands on the last whorl often 

 very faint that corresponds to the three rows of spots on the typical 

 Donnani. and many of them have just enough spots, very faint ones 

 to show their relationship. However, the lightest Dormani I have 

 seen in any other locality will show several times more spots and 

 color than the darkest ulbida I have seen. All the Florida Buli- 

 muli I have seen show more or less of bands on some examples, but 

 these show much more trace of bands than the horn-colored Buli- 

 muli that we have occasionally found along the east coast for a dis- 

 tance of 200 miles. Tliat there are no typical B. Dormani in the 

 hammock where the albida are found, I am quite sure, as it is only 

 three miles from our home and we often go there and have looked 

 over about the whole ground many times, finding I think 27 species 

 of shells. We have found two types of Bulimuli near the east coast 

 both of them much like Binney's No. 449, in form, but very unlike 

 his 448. They are very fragile shells, one of them nearly white 

 with conspicuous bands and the other plain horn color. Whether 

 they are to be called Floridana or Hemphilli, I think that fur the 

 accomodation of collectors and students they should be distinguished 

 by different names. If a collector should write to me for B. Hemp- 

 hilli expecting to get a white banded shell and I should send him 

 a horn-colored one he would have good reason for being disappointed. 

 So far we have found them to be very rare shells. 



CONCHOLOGICAL NOTES FROM OREGON. i 



* * * During my recent visit to Oregon I had opportunities 

 for seeing Goniohasis plicifera Lea living in the Columbia River 

 near Astoria, mostly on stones in small pools along the rocky mar- 

 gin. Also G. nigrina Lea "which occurs in large numbers in the 

 brook running from several large springs near Susanville, Lassen 

 Co., Cal., at an elevation of 4700 feet above the sea. The same spe- 

 cies was noticed in a watering trough fed by a spring on the road
