In mentioning the genus Macha Edg. Smith (loc. cit.) says "Hermannsen (Indicis 

 Gen. Malac. Vol. II p. 1) quotes Macha as de.scribed by Oken in 181Ô ; but I have searched 

 in vain in the "Lehrbuch" (Lehrbuch d. Naturg. Vol. Ill) for any mention of this 

 genus, which should therefore date from 1835." Herrmannsen himself had alreadv 

 in the Supplement to "Indie, gen. Malacozoor." 1852, p. 78, corrected the date, in 

 his statement concerning Oken's description of Macha, from 1815 to 1835.
