5 months, 2 weeks ago5 months, 2 weeks agoI named it using the mentioned paper. I believe that measurements were provided in the data. Once again it is packed away somewhere so I cannot reshoot it with a scale. I have heard that you can add a scale next to the photo using the measurements provided.

Pay special attention to the field collecting attire of both the men and women while on an outing; I could not imagine wearing these while collecting in Florida or Texas during the summer.
