Description
These photos were attached to a brief letter written in October of 1939 by colleague Frank M. Swartz.
"I was glad to hear that the specimens reached you safely, and I wish to thank you again for the loan of them. I am enclosing copies of the photos I prepared, together with copies of the photos you sent me last year.
I was especially pleased to see the small spines of the anterior limb of the [thoracai?] segments (see photo.) These are less divergent than in the [Sherwin?] material. There are a whole series of small differences between the New Scotland and [Sherwin?] forms, so that I am inclined to regard them as distinct species."
The writing on the page of photos is probably his, though it is hard to tell.
