What is mtype320 and mtype16 in Cooja?

Question

I have a simulation file, called myfile.csc that I can load it into the Cooja Simulator. This file includes two types of nodes. The first one is mtype320 which is used as the sink node and mtype16 that is used for regular nodes. I would like to know which types of modules/hardwares (SKY, Z1, CC430, ...) they represent. Because when I open GUI of Cooja and want to add a new mote with these types (mtype320, mtype16), I can not find it in the list that Cooja provides.

My csc file is like this:
