He did not indicate whether there are other paratypes. In addition to the holotype, the register has three specimens identified as rennelli in Troughton’s handwriting, only one of which is marked as a type (M.4214 as allotype). The two remaining specimens M.4215–16 are marked “ Paratypes 2 juv spmns” in Troughton’s hand on a type specimen index card.There are no other Rattus registered from Rennell Island in the AM database.
