THE CLINTON SERIES. 



Durino- the past Summer, when staying at AMnona Park, 

 I paid several visits to "The Gibson Quarries," formerly work- 

 ed there and now abandoned, in order to secure (chiefly) as 

 many portable Upper Clinton Slabs as possible displaying Dr. 

 Hall's Fucoid ''Arthrophvcus Harlani." ]\Iany specimens 

 were obtained in fine preservation for the Redpath ]Museum 

 and general distribution. One in the side case of the jNluseum, 

 to which I may call particular attention, clearly proves how er- 

 roneous it was to suppose that any "Crustacean" or "Anne- 

 lid" could ever have produced the impression on the flags. 

 ^vhen the lobed nodules on the surface extend to the sides of 

 the branches also. A single branch displaying a tuft of others 

 ai the extremity has been placed in an upper case of the l\In- 

 seum. 



The Iron Band of the series aft'orded an interesting 

 "Lamelli Branch." It appears to be a species of Conrad's 

 "Leiopteria," that has only been found in higher beds, and 

 in the absence of "the Type Species" for comparison, it would 

 be very unsafe to rely altogether on mere verbal description, 

 more especially since we have only the impression of "a flat- 

 tened singfle valve." 



A large slab containing several branches and portions of 

 the main stem of Hall's Fucoid "Buthotrephis" was extracted 

 from the lower Green Band and placed in a side case with a 

 few other Fossils of local interest. 



The ]\Iedina Beds presented nothing new. In a work by 

 Professor C. Schuchert, Washington, a great man}" alterations 

 have been made recentlv in the nomenclature of "the Brachio- 

 pods" bv the Chief Palaeontologists of "the United States," 

 imder the sanction of "the Director General of the Survey, 

 C. D. AA'alcott. If the changes intimated are generally ac- 

 cepted for the reasons assigned, this section cannot lag behind 

 recent discoveries which- led to it, and must conform also. 

 Probablv some of the men attending the lately established 

 College here from other parts of the Dominion mav wish to
