Golfe de Siam (“sur le littoral occidental du Cambodge,” Pavie). 
The Danish Expedition to Siam collected no specimens of this species. 
Distribution: — Andamans, Wasin Isl. (East Africa). — Java, Philippines. 
In mentioning the genus Macha Epc. Smirn (loc. cit.) says “HERMANNSEN (Indicis 
Gen. Malae. Vol. II p.1) quotes Macha as described by OKEN in 1815; but I have searched 
in vain in the “Lehrbuch” (Lehrbuch d. Naturg. Vol. II) for any mention of this 
genus, which should therefore date from 1835.” HERRMANNSEN himself had already 
in the Supplement to “Indic. gen. Malacozoor.” 1852, p. 78, corrected the date, in 
his statement concerning OKEN’s description of Macha, from 1815 to 1835.
