gentleman lately submitted for inspection one he found in the 

 Niagara rocks there. It possessed all the leading characteristics of 

 .the group, and may be a different species. He was greatl}' inter- 

 ested in the case containing the Hamilton sponges, and accurately 

 described the transverse section of another species, which displays 

 a large " osculum " encircled b}'^ many smaller ones. I fear we 

 have not evfen a section in the museum. As the Chicago professor 

 was a friend of Dr. Head's, who has already named and described 

 "Atilocopina Walkeri," and other Hamilton sponges, the writer 

 availed himself of the opportunitj^ to furnish him with duplicates 

 of a few forms which may not have been described already by Prof. 

 Rauff. As well as I can remember the parcel sent by Mr. Walker 

 to Germany consisted chiefly, he remarked, of sections, not com- 

 plete sponges. 



While congratulating ourselves in spring on the nature of the 

 crops planted, in some of the best places for collecting unfortun- 

 ately later on, when the oat crop was harvested, it was ascertained 

 that clover, grasses and weeds had entirely concealed the surface 

 of the field adjoining "the corporation drain," the one which for 

 many years furnished us with numerous flint-flake fossils, from 

 the glaciated Niagara chert beds, corals, brachipods, bryozoons. 

 A portion of the next field close to the ience afforded me some 

 fragments of bryozoon {Lichenalia) recently. Many years ago on 

 turning over some of the flint-flakes there, I discovered a fine 

 specimen of 'R^lVii cornulites bclla striata, and another more flexible 

 form equally well preserved. We cannot expect much success in 

 securing many specimens until the cows, horses and sheep are 

 turned into the stubble fields and frost puts in its appearance to cut 

 down the weeds which the cattle decline to eat. 



Your Curator has at last succeeded in getting one of the Para- 

 site Lichenalias attached to one of the plain globular sponges. He 

 thinks, however, it may prove to be a different species from the 

 ones previously found in the upper portion of the flint-flake fossi^ 

 field adjoining the corporation drain. This specimen is from the 

 brow of the escarpment beyond the Hamilton reservoir. The dif- 

 ference as regards distance may not amount to much, since nearly
