ings style following their publication in the newspaper; 
but it is uncertain when the Proceedings signature bear¬ 
ing the Ayres presentation was issued other than in early 
April. Whatever the case, the taxon must be dated as of 
6 April 1855. 
The article was reprinted in 1873 (p. 39-40) in what has 
become known as the “Second edition,” in which the 
original text was reset so that there is some discrepancy 
in pagination with the original publication (see com¬ 
ments by R.E.C Steams, 1873, Prefatory Note to This 
Editon. PCAS, 2nd ed., 1:[unnumbered p. 1]).)

signature that bears the printing date of April 9.)

(Pages 41-42 are part of a 4-page signature dated April

(Paper presented at the Academy meeting held on 16 
April 1855. The presentation appeared in the The 
Pacific, a newspaper published in San Francisco, on 20 
April 1855. Ordinarily, the newspaper columns were 
then rearranged and printed in a signature in Proceed¬ 
ings style following their publication in the newspaper; 
the signature, including pages 43-45, carries only the 
month, April, but it is flanked by signatures dated April 
9 and April 30. Nonetheless, the taxon can be dated as of 
20 April 1855.

ture that carries only the month, April, but it is flanked 
by signatures dated April 9 and April 30. Inasmuch as 
the paper was presented on 30 April, the signature,

April 1855. The Proceedings pages 47-48 are included 
in a 6-page signature [47-52] dated April 30. However, 
the presentation appeared in the The Pacific, a newspa¬ 
per published in San Francisco, on 4 May 1855. 
Ordinarily, the newspaper columns were printed first 
and then rearranged and printed in a signature in Pro¬

paper. Whatever the case, the taxon can assuredly be 
dated as of 4 May 1855.
