PARTITION TYPES
The gpart utility uses symbolic names for common partition types to avoid
that the user needs to know what the partitioning scheme in question is
and what the actual number or identification needs to be used for a par-
ticular type. The gpart utility also allows the user to specify scheme-
specific partition types for partition types that do not have symbol
names. The symbolic names currently understood are:
...
freebsd A FreeBSD partition that uses the BSD disklabel to sub-
divide the partition into file systems. This is a legacy
partition type and should not be used for the APM or GPT
schemes. The scheme-specific types are "!165" for MBR,
"!FreeBSD" for APM, and
"!516e7cb4-6ecf-11d6-8ff8-00022d09712b" for GPT.

Seems you forgot to read the manual page carefully. ;-)
