ICMP is an IP protocol not an Ethernet Protocol. It's protocol number is 1, for the rest see the IANA assignments document.

Just to add a little bit, echo-request is ICMP Type 8 and echo-reply is ICMP type 0 – Zypher♦ Feb 9 '10 at 22:45

Sounds more like a little byte to me ;) – einstiien Feb 9 '10 at 22:50

@Zypher nicely clarified. – Helvick Feb 9 '10 at 23:17

In addition, the ICMP code number returned with the type can be invaluable in troubleshooting: en.wikipedia.org/wiki/Internet_Control_Message_Protocol – joeqwerty Feb 10 '10 at 3:39

The Ethernet protocol number would be 0800, as for any IP frame.
