and Erismatura are mentioned, is wrong, as I have already 

 shown (Ibis, 1888, pp. 320-325), and ought to be 1841. The 

 mistake is avoided as regards the genera Lusciniopsis and 

 Pseudoluscinia, so that I suppose that the sheets containing 

 the other generic names were printed before my paper 

 appeared. 



The genus Chettusia, Bp. (Iconogr. F. I. Tntrod. p. 9, 1841, 

 not 1839) , is not mentioned also on p. 115, tabl. xli. of the same 

 work, as Mr. Waterhouse states. On the plate xli. (dated 

 1838) there is only the name Vanellus gregarius, and in the 

 accompanying text Chettusia gregaria is simply the Italian 

 name printed under that of Vanellus gregarius (cf. Ibis, 1888, 

 p. 323, note). 



Erythrospiza, Bp., was established before the " Saggio/' 

 pp. 53, 141 (1831), in the work which bears the title ' Sulla 

 seconda edizione del Eegno Animale del Barone Cuvier; 

 Osservazioni/' p. 80 (1830), (cf. Ibis, 1888, p. 320, note). 



Eurhynchus, not quite correctly attributed to Latreille, was 

 mentioned by Lesson, ' Tr. d'Orn/ p. 183 (1831), and Used 

 by him, ' Complements de Buffon, Ois./ p. 603 (1837), before 

 Gray, 'List Gen. B.' p. 53 (1840). 



Microglossia, Geoff r. St.-Hilaire. As Mr. Waterhouse 

 rightly states, Vieillot published this genus in the ' Galerie 

 des Oiseaux/ i. p. 47, pi. 50, only the date 1825 is not quite 

 exact. In fact he took it from Geoffroy St.-Hilaire, who, in 

 a memoir, " Sur les Appareils de la Deglutition et du Gout 

 dans les Aras Indiens, ou Perroquets Microglosses " (Mem. 

 du Mus. x. pp. 186-198, pi. 11. figs. 13, 14, 16, 1823), pro- 

 posed the French name " Microglosse." The memoir was 

 read the 6th July, 1821, but was not printed till 1823 ; at 

 the end of it (p. 198) there is a note in which Geoffroy St.- 

 Hilaire states that the genus Microglosse had already been 

 published in the ' Galerie des Oiseaux ' by Vieillot, to whom 

 he had communicated his memoir. 



From all this it is quite evident that the date of the genus 

 Microglossia must be between 6th July, 1821, and 1823. I 

 may remark, by the way, that the ' Galerie des Oiseaux ' was 

 published in eighty-two parts, from 1820 to 1826 (see Engel-
