Not that sort of pug nose.

In the Kingsley Amis story “The Mystery of Darkwater Hall” (it’s a Sherlock Holmes pastiche), the villain, a local ruffian named Black Ralph, is described as having a “simous and ape-like appearance.” I pulled a blank on “simous.” Most dictionaries now label it as obsolete. It comes from the Latin simus (which in turn came from the same word in Greek) and means “snub-nosed.” I found a more general definition for it as concave or curving in, but in practice doesn’t seem to have any application other than referring to a flat or snub nose, perhaps with a curling tip. I saw one definition calling it a pug nose, but I’m not sure if that means the same thing. Though since nobody uses simous anymore perhaps it does. As for “pug,” it’s not clear where that word came from but it seems to have been first used as the name of the dog breed. People with a flat nose are said to have a pug nose in reference to the dog breed, not the other way around.
