Because the description was based mostly on the two specimens from Guadalcanal, the name _rayneri_ is applicable to the bats from that island. Andersen (1908:365) thought that specimens that he studied, from San Cristobal, were specifically distinct from _P. rayneri_ and he proposed the name _Pteropus cognatus_ for them. Later, Hill (1962:9) reduced _cognatus_ to subspecific status under _P. rayneri_. Presently _P. r. cognatus_ is known only from San Cristobal and the small adjacent island of Ugi (see Fig. 6). =Pteropus rayneri rennelli= Troughton 1929. _Pteropus rennelli_ Troughton, Rec.

Hill (1962:7) reported two additional specimens and pointed out that _P. r. cognatus_ and _P. r. rennelli_ probably represent the extremes of an east-west cline in size. _P. r. rennelli_ and _P. r. cognatus_ differ from other subspecies of the species in lacking tricolored pelage on the dorsum, but their short rostrum clearly indicates affinity with other members of this complex group in the Solomon Islands (Hill, 1962:8). The relationship of the subspecies _rennelli_ and _cognatus_ is close, both geographically and genetically. Longer forearm, longer metacarpals, and longer mandibular tooth-row serve to differentiate _rennelli_ from _cognatus_. =Pteropus woodfordi= Thomas
