without any reason, while he admits the possibility of its being a 

 bryozoan. Chetetes newberryi is now Jlonticulipora (Prasopora) 

 newberryi. Jfonticulipora sclwyni, var. hospitalis, is a new encrusting 

 variety. Chetetes frondosus is now Jlonticulipora (Peronopora) 

 frondosa. Chetetes ortoni is Jfonticulipora (Peronopora) ortoni- 

 And Jlonticulipora cincinnatensis is referred to his subgenus Perono- 

 pora. 



The medley of forms under the subgenus Jlonotrypa is quite as ob- 

 jectionable as those arranged under the head of Heterotrypa, beside 

 including true Bryozoa with true Potypi, if these classes are found in 

 the Hudson River Group. 



He proposes that Jlonticulipora lycoperdon shall be dropped alto- 

 gether, and that no attempt shall be made to revive it, but that a new 

 name, which he proposes, shall be adopted in its stead. The reasons 

 which he gives for so doing are not laid down in the laws of nomen- 

 clature, nor do they address themselves to the mind of an ordinary 

 palaeontologist. He seems to be quite innocent of the literature upon 

 the subject, but familiar with some of the mistakes that others have 

 made in identifying other forms with it. His philosophy, applied to 

 other species, would suppress Monticulipora petropolitana in Russia, 

 because he had made a mistake in referring an American form to it; it 

 would suppress Jlonticulipora pulchella, in the Wenlock of England, 

 because he had identified Jlonticulipora fibrosa, of America, with it; 

 and so on, indefinitely, specific names would be suppressed on account 

 of the subsequent blunders of others. 



The specific name, lycoperdon, is attributed by American palae- 

 ontologists to Say, though he did not describe the species. He 

 was an eminent naturalist, and seems to have called it Favosites lyco- 

 perdon, by which name it became generally known from its puff-ball 

 shape. In 1842, Prof. Emmons figured it under the name of Favosites 

 lycopodites, as characteristic of the Trenton Group, of New York.* He 

 that he had not discovered it as high as the Utica Slate, and if any 

 fossils are characteristic of the Trenton limestone, this is certainly 

 one (p. 400). In the same year, Prof. Vanuxem figured and described 

 it as characteristic of the Trenton Group, of New York.f He said, in 

 referring to the illustration: '-The Puff-ball favosite (Favosites 

 lycopodites), from its resemblance to that common fungus, is also 

 highly characteristic (of the Trenton limestone), and is in great num-
