This one looks to us like a Philinopsis sp, with a very high, tapered headshield 'horn'. I'm not sure it comes across in the photos, but it was quite translucent.

This is a strange looking animal. It certainly has the look of an aglajid, such as Philinopsis, but in your last photo, the headshield 'horn' is very reminscent of a gastropterid, or mote specifically a Siphopteron. The body wall does appear very transparent, and because of that I am not sure whether the yellow-brown shell we can see in the photo alongside, has a foramen or hole thought the dorsal mantle wall, or just that the mantle wall is very thin at that point.
What ever the situation, I think we are stumped without an animal to loook at or even a shell. It is always possible that the empty shell has been found, and named and placed in one of many genera, but we will never know until another animal is found and the shell removed for comparison. Until we know more I will call it Aglajid sp. 9
