Herpetology Resources

Loan Policy

Loans of specimens are made at the discretion of the curator-in-charge to institutions under the name of a permanent staff member of the institution. Specimens must not be moved to another address without written permission from Academy of Natural Sciences. A loan request from a student must be countersigned by their major professor who will assume responsibility for the specimens.

Herpetology Collections

No more than one-half of the total specimens of a species will ordinarily be lent at a time. The remainder may be requested after return of the first loan. Series of specimens from single localities may be borrowed as units so long as they do not exceed one-half of the total. Fragile specimens (e.g., certain skeletal and larval materials) will ordinarily not be lent. Non-type specimens are loaned for a period of one year. Holotypes and paratypes are loaned separately from other specimens. Type material is loaned for a period up to 6 months.

The recipients of loans must agree to the conditions for handling and use of the specimens stated in the Loan Agreement below.

Loan Agreement

Recent research on conservation problems in our collections has shown that many specimens are more delicate than we had previously assumed. Therefore, we have instated the conditions below for handling and use that must be agreed upon in order to receive material on loan from the Vertebrate Zoology Department of the ANSP.

  • Gentle compressed air may be used to clean a specimen. No other cleaning may be attempted without written permission.
  • No repairs may be made to specimen(s) unless written permission is obtained. Please do not use any kind or glue or other adhesives.
  • No coatings (including sublimated ammonium chloride or magnesium oxide, or SEM coatings), stains, consolidants, molding media, separators, etc., may be applied without written permission.
  • No sampling or destructive analyses of any kind are to be performed on specimens without written permission.
  • Competent specimens may be measured and photographed. Please minimize exposure of specimens to hot photofloods.
  • All efforts must be made to store specimens under stable conditions that would minimize exposure to dust, and fluctuations in temperature and relative humidity.
  • All contents of each specimen should be returned, including all labels, contained sediments, etc. Original data labels many not be written on under any circumstances. Any systematic change contemplated, especially type designations, or comments regarding a particular specimen, should be annotated with the specimen upon its return, on a separate slip of paper. Please include the ANSP catalogue number, the name of the person annotating the specimen(s), and the date the annotation was written.
  • It would be greatly appreciated that relevant reprints regarding any of the loan specimens be sent to the Vertebrate Zoology Department when they become available.
  • Specimens must be unpacked and repacked with care, preferably using the same material(s) with which they were received. Please be aware that specimens are easily broken by over packing and by insufficient cushioning.
  • The loan must be returned by the time stipulated, unless a loan extension has been granted.
