White (who later became Ichigo's Zanpakuto spirit) couldn't really be counted as a Menos for several reasons:

1) Any Adjuchas-level or above Menos has intelligence and is capable of speech. White is not. White was little more than an animal mentally.

2) He was a product of science, therefore, normal Hollow classifications shouldn't apply to him, since the only person who really knows what he is would be Aizen.

3) He's an Inner Hollow that has taken over, so calling him a Vasto Lorde would be similar to calling all the other Visords Vasto Lordes the night their Inner Hollows took over and rampaged. Inner Hollows evolve with their Visored, so he was just as strong as Ichigo, just lacking morals and style.
