nigrescentibus. = Collum subtus, pectusque superiori parte, smaradigno 

 splendent, in viridem cerulescentem varianti. = De pectore ad abdominis 

 medietatem, nigro velutinus est, in aureo-olivaceum transiens, crisso 

 fusco-aureo, caudaque aliquantulum furcata, tripollicari, rectricibus aureis 

 apice rotundatis. [p. 4S.] 



Obviously, this is Eugenes fu Igens (Swains.), 1827. 



T. [rochilus] Topiltzix. = Rostrum rectum, nigrumque est, pollice 

 paullo majus. = Corpus subtripollicare, lincola alba ad latus occuli. = 

 Caput zaphirimi splendoris aliquamtullum reflectit, corpore supra deau- 

 rato, remigibus fuscis, rectricibus nigrescentibus, apice amplis et albis, 

 caudam componentibus, tripollicarem et rotundatam. [p. 49.] 



This is evidently Ca'ligena dementia (Less.), 1829, but the colors 

 of the throat and crown are transposed. 



ON THE DATE OF LACEPEDE'S ' TABLEAUX.' 



BY CHARLES W. RICHMOND. 



In 'Natural Science' for Dec, 1897, 432, Mr. C. Davies 

 Sherborn has brought forward a very interesting subject — that of 

 the first published appearance of Lacepede's ' Tableaux,' usually 

 credited to the Memoires de l'lnstitut, 180 1, but as this writer 

 has noted, sometimes cited vaguely " 1799." During his efforts 

 to solve the question of date, Mr. Sherborn discovered these 

 1 Tableaux ' in the " Didot " edition of Buff on, at the end of Vol. 

 XIV of the Quadruples, which, it appears, bears the date 1799 

 upon its title page. The "Didot" edition, in i8mo, is said to 

 consist of 76 volumes, dating from 1799 to 1806; the genera, Mr. 

 Sherborn states, are to be credited to Lacepede, and the species 

 to Daudin. The latter doubtless here described various birds 

 intended to appear in his ' Traite,' l and an account of them, by 



1 To have been completed in 6 volumes, according to the prospectus in the 

 Journ. Typographique. Vol. 1 was published Jan., 1S00; vol. II, publ. May. 

 1800, and the third volume was in the press and would not be long in appear- 

 ing (Journ. Typ.). It was, however, never published.
