Bertie Wooster and Jeeves in “The Hunger Strike”

I can't understand Gussie Fink-Nottle being in London, Jeeves. Till now he's always remained glued to the country, completely surrounded by newts.

Sir?

[speaking to doorman] Morning, Jarvis. [turning again to Jeeves] Newts. You know, Jeeves, those little lizard-y things that charge about in ponds.

Ah, yes, sir. The aquatic members of the family Salamandridae that constitute the genus Molge.

Yes, they're the chaps.
