The rollers were recorded on the same expedition as Koch-Grünberg I, but archived as a separate collection for technical reasons. The rollers of the second collection are labelled : Koch-Grünberg Brazil II resp. Venezuela. W. 19 was included in the dem. coll. as no. 71. According to the diary entry, the rollers were taken during some rest days in Sao Felippe (21.2. - 2.3.1913). Source: Estate of Th.K.-G., Völkerkundl. Samml.
