32 Under reference to 27th Regents Report add ; The two dif-

 that the plates illustrating the descriptions published in 

 1872, were not published until 1875 when the 27th Report 

 was issued. These plates are numbered "24th Report," 

 and should always be included with it, though not pub- 

 lished until three years later.
