1. List of Stamps Arranged by Country

   Note:  Mexico #C 380 has been deleted from the listings, because the object reported to be a turtle is almost certainly not one.

2. Appendix II:  Labels, Seals, Advertising Stamps, Etc.

   PAKISTAN UNISSUED - 1981  

   This is a 1981 proof of a proposed stamp that was never issued because it lost out to another proposed stamp with a sea turtle design. The tortoise depicted on this proof is a leopard tortoise (Geochelone pardalis).

   PPP LABELS  

   Two gummed, perforated labels of unknown origin and date. One depicts two sea turtles (Eretmochelys imbricata?) and the other depicts a box turtle of the genus Terrapene. Each label has a small monogram with the initials "PPP" in it in the lower left corner and a copyright symbol in the lower right corner. The box turtle label also has some illegible writing next to the copyright symbol. The meaning of the PPP monogram is unknown. The box turtle label is inscribed "No. 77" in the top margin and the sea turtle label is inscribed "No. 80" in the top margin.
