Published in memoir read 

 before and deposited with 

 the Am. Phil. Soc. March 

 16, 1832, and printed in 

 Trans. V, 23. I was absent 

 most of 1832 in Europe, 

 and the large number of 

 plates (19) with figures of 

 86 species, in this and the 

 two following supplements, 

 all colored, required much 

 time, and it was not until 

 some time in August or 

 September, 1834, that the 

 whole was finished and 

 issued printed. 



Supplement read before 

 and deposited with the 

 Am. Phil. Soc. March 15, 



1833, and printed in Trans. 

 V, 59. The same obsel^fa- 

 tions apply as to the pre- 

 ceding. 



Second supplement read 

 before and deposited with 

 the Am. Phil. Soc. Feb. 7, 



1834, and printed in Trans. 



V, 95. The same observa- 

 tions apply as to the pre- 

 ceding. 



Published in memoir read 

 before and deposited with 

 the Am. Phil. Soc. Dec. 19, 

 1834, and printed in Trans. 



VI, 1. All these are in- 

 serted in the first edition 

 of my Synopsis, issued in 

 1836, probably in Dec. 



• I cannot understand why Mr. Conrad dates this one year prior to the other species in 

 the same memoir. In his Synopsis he makes it a synonym to Mortoni Con., which he 

 described in Ho. 1 of his Monograpby, December, 1S.35.
