Hi Nige...

The first snail is most likely Cepaea nemoralis, these are our largest native land snail...You can get a brown lipped form of C. hortensis, so it is best to take a look about to see if you can find more of the same type. I had one last year from the banks of a reservior near the Beacons.

The second is Oxyichilus navarricus helveticus. The dark area near the mouth of the shell and the white clouding around the umbilicus helps with this snail...this snail also gives off that garlic smell.

The first slug looks like a Deroceras of some type, D. laeve and D. panormitanum seem the most likely to me. D. laeve are found in wet habitats.

The second slug looks like its Arion hortensis or A. distinctus. I would put it as Arion hortensis agg

Regards Chris...

Are there many similar species to this? Only last year I counted about 40 on one small stretch of fence outside my house

I had 4 of what you see in the picture in my garden yesterday.

I will try and find it again and give it a sniff

This was under a bin next to my rabbit hutch, so not particularly wet around there, but it had been raining

Any reason?

Many thanks again for you help!

There are a few other banded types of varying degree (off the top of head...Cernulla virgata, Candidula interscta, C. gigaxii, Theba pisana and Cepaea sp) some will have an open umbilicus others will have the umbilicus sealed or obscured by the mouth lip. With all snails its good to look at both sides, also note size, habitat and check around for others of the same type. The Brown lipped snail Cepaea nemoralis and the White lipped snail C. hortensis won't have this open umbilicus like you have shown in your 2nd snail photo...if you come across them again, put them on WAB and see if we can get an id for you.

Good to add flavouring to your Spaghetti bolognese.

Oxychilus alliarius will also have this Garlic smell...

Lol...looks probable for D. panormitanum then.

Arion hortensis and Arion distinctus can vary quite a bit in colour (same as most slug). Dissection is usually needed to confirm, at least untill you get used to what is in your area. There is also another that can lead to some confusion with the A. distinctus and that is A. owenii...it is also usefull to note the colour of the sole of the foot in slugs.
