NOTES ON THE LATE COLLECTING SEASON 



While disappointed in not finding a few more of the 

 Ohio specimens of last and preceding 5^ears, yet perhaps 

 the late summer visit to the lake shore, considering the cir- 

 cumstances, may not be thought unsatisfactory. I found 

 among the specimens brought in from Winona a fine slab 

 containing several mem.bers of James Hall's Minute Brachi- 

 opod (Septobolus Occidentalis). The doctor records it as 

 occurring in the Hudson River series. The writer supposes 

 it may be found also in the Trenton still lower, but as 

 other specimens were associated with fossils which are com- 

 mon to both, it must be admitted, the evidence on this point 

 is very unsatisfactor}'. 



Tw^o valves of the Trenton lyamelli branch, separated 

 (Modiolopsis Gesneri, Billing's), in good preservation, were 

 obtained. It may be inferred that the one described w^as 

 the only one known to the Palaeontologist, it appears to be 

 by no means rare in the shore shingle, or glacial clay, near 

 Winona, but as a general rule it is difficult to extract it un- 

 injured. The specimen now produced is much superior to 

 any found previously. 



An appropriate name for a Bellerophon extracted from 

 beach shingle was given by Sowerb}^ to a Devonian form in 

 England many j^ears ago. Probably it is known already 

 here or in the States, but I have not seen it figured or 

 described. There were two specimens on the slab, and 

 after I had secured the one, a young fellow who was with 

 me requested me to let him have the other if he succeeded 

 in getting it out, as he wished to show it to some friends. 

 We were all, he said, greatly interested in an astronomical 

 lecture given by Dr. Marsh some time back, a member of 

 the Hamilton Association. Under such circumstances, I 

 could not well refuse. His was far superior to mine. 



The glacial clay furnished a fine specimen of an 

 Orthoceras, which may be an intermediate form between 

 Orthoceras Simulata and Oregulare. I forget the name 

 attached to the latter by American Palaeontologists, but the
