40 The Ottawa Naturalist. [June-July 



did, and after several minutes of continual hissing the silence 

 when they stopped could almost be felt. 



When we offered them a stick they attacked it with their 

 beak, and occasionally struck at it with a foot, but they had 

 not yet reached the age when the uses of their feet were pro- 

 perly appreciated. After a while a ildness seized four of them 

 and they rushed around the room, and one went out through a 

 small hole and flew away. Where he went to is still a puzzle, 

 but no doubt his parents found him at night. 



The old ones do not appear in the day time, but come to- 

 wards evening with food, and they have always been silent ever 

 since they arrived in February, the hiss being the only sound 

 Mr. Hunter has heard from them. 



The only recent record of these birds for Ontario was when 

 two were taken, one at Pelee Island and one at the base of Point 

 Pelee in 1914, and there are a few other records of the occurrence 

 of the bird, but this, I believe, is the first nesting that has ever 

 been reported. 



SOME NOTES ON FOSSIL COLLECTING, AND ON THE 



EDRIOASTEROIDEA. 



By George H. Hudson. 



Part II. 



(Continued from page 25.) 



Bather's "Studies in Edrioasteroidea," which appeared in 

 the Geological Magazine at different times from 1898 to 1915 

 inclusive, have now been collected into one volume and pub- 

 lished by the author at "Fabo," Marryat Road, Wimbledon, 

 England. In this reprint the dates and paging of the Geological 

 Magazine have been retained, and our references will, therefore, 

 apply to both the original papers and the reprint. As examples 

 of thorough study of what specimens have to reveal, these papers 

 are unexcelled. It is highly probable, however, that the speci- 

 mens themselves lack structures they once possessed, and that 

 such structures will yet be found, either in more complete in- 

 dividuals or in fragments. Before specifying what I believe 

 will be the nature of such finds, let me give some instances of 

 structure rarely preserved. 



Of what he calls the "tubular pyramid" on Pentremites, 

 Hambach says ("Notes about the Structure and Classification 

 of the Pentremites,"; Trans. St. Lotiis Acad, of Science, Vol. 

 IV, No. 3, p. 6): "The only species on which Dr. Shumard ob- 

 served the same, was a specimen of P. sulcatus, Roemer
