I am not an expert

But the first one looks like a Cleoniceras

And the 2nd a Douvilleceras

 

Both from Madagascar

I'll go along with Douvilleiceras for the second one, but I'm not at all sure if the first is a Cleoniceras due to the spines on the keel, the groove along the flank and also the extremely involute umbilicus, all of which are sculptural features which are failing on Cleoniceras. I'm not sure what it is, although I've already checked around a bit.

Now that I've had time to think about it, Ochetoceras sp. comes to mind.

Thanks!!!!  I researched the names provided and I concur with Ludwigia on the first specimen and both of you on the second specimen.....  Thanks again for all your help!
