   • Mikarew: should be in genus 53.5 (Mikarew), not in 53.3 (Lower Ramu)

4. Feature description error/omission (1)

   The text for feature 40 (”Exclusive/Inclusive Distinction in Verbal Inflection”) does not mention that only person affixes in “subject” function have been taken into account.

5. Typos (3)
   • p. 286: runáját > runájiet
   • jacket back: demonstrativennoun and nounndemonstrative
   • p. 367; examples 7a and 7b; ergative suffix: – e > -ɹe
6. References in electronic version

   All errors concern Sharma 1989a/b/c and Sharma 1992

   Tod:

   Lists the data source (for velar nasals) as Sharma 1989a, and lists the reference as Sharma 1989c, whereas in fact these should both be Sharma 1989b.

   Tinani and Gahri:

   The references listed are b and c, when it should only be b. And while the data source is correctly b for Matthew Dryer’s maps, for both it is incorrectly listed as a for the velar nasal map.

   Pattani:

   As with the last two, the references listed are b and c, when it should only be b. But this time it is right for velar nasal, but wrong for my maps, where (at least for some of them) it is listed as a.

   Spitian and Nyamkad:

   Two references are listed, a 1989d and a 1992. But these are the same source, and the correct year is 1992. There should be no 1989d. Furthermore the data source for chapter 9 (The Velar Nasal) is listed as 1989b. Matthew Dryer’s maps are correct as 1992.

   Jad:

   Here the data source (only on Matthew Dryer’s maps) and the reference are both listed as a, which are both wrong, since the source is c.
