Looks like it to me.

<man traceroute>

"The only mandatory parameter is the destination host name or IP number.
The default probe datagram length is 40 bytes, but this may be increased
by specifying a packet length (in bytes) after the destination host name.
...

 -p Set the base UDP port number used in probes (default is 33434).
Traceroute hopes .... "
</man traceroute>

Notice the Length of 40 and the destination port ~ 33400 + <probe number>

hope this helps.
