Last element in Backbone collection add / reset?

Question

How do you know if a model is the last one in the batch?

   // inside view    
collection = new ObjectCollection();
this.listenTo(collection, 'add', added);

added: function(mod){
    //if(mod.position.last)
}

collection.add([{'name': 'Human'}, {'name': 'Cat'}]);

http://backbonejs.org/#Collection-at

added: function(mod){
    if (this.collection.at(this.collection.length-1) == mod) {
      //do stuff
    }
}
