Get first two strings of each filename in a directory as a txt file

I need to clean up strings like this (where I read in a group of image names), where I only want the first two strings (currently I'm using, in Windows 7 cmd line - dir /a/b/p > textfile.txt):

• Acaena inermis no barbs dbot_25Dec15_40.JPG
• Coprosma Taiko PB121944 invbot.rs.JPG
• Cortaderia richardii InvBot P6260038.JPG
• Anemanthele lessoniana LIC.nestmaker.CC BY-SA 2.0.jpg
• Myosotidium hort ibot PB109882 sqr rs.JPG

to look like this:

• Acaena inermis
• Coprosma Taiko
• Cortaderia richardii
• Anemanthele lessoniana
• Myosotidium hort

Is there a way using either cmd or batch to simplify this? Normally there would be 15 files parsed each time I do this. I'm hardly a cmd-line guru!
