Types on loan from USNM to NHMU

After a request to the US National Museum, they sent the first of three loans of Type Specimens to the Natural History Museum of Utah.  Types are the specimens used to compare to other specimens to verify the others are typical of the type.  Syntypes are usually from a series of types where neither a Holotype or Lectotype have been designated.
Syntype of Wyomingites aplanatus (White 1879)

paperwork

Holotypes are single specimens showing what all other specimens of that species should look like.

Holotype for Danubites strongi  Hyatt & Smith 1905

Paperwork in the box



Jim and I will be examining these types over the next few weeks or months as they come in.  There is a lot of revising and/or synonymizing to do.  What was thought to be typical may actually be atypical of the type.


Holotype of Xenoceltites cordilleranus (Smith 1932)

Thanks to Dan Levin at the Smithsonian Institute, and Randy Irmis and Carrie Levitt-Bussian at the NHMU for helping and facilitating the loan from the USNM, we really appreciate their help and hospitality.
