During the months of Julio to December, 2008, compilations were effected of especimenes of terrestrial snails in 06 geographical points of the region of St Martin, prioritized according to empirical information of his prevalencia, wherefrom the information decided georefencial using an equipment GPS(GLOBAL POSITIONING SYSTEM), all this process I develop in five phases or stages that were: 1) Conditioning cage, 2) Summary of information of prevalencia of the terrestrial snails, 3) Compilation of the specimens of snails and local characterization, 4) Conditioning of the terrestrial snails in his cages, 5) Morphologic characterization. They were predominantly especimenes of giant snails, known like "congompe" and "pucashimi", a major proportion of the second one being brought. The presence of snails in only six of ten zones of collection established, and in them the scanty existence of "congompes", indicate us that in the above mentioned zones the extraction of these was excessive, that exists a destruction of his habitat natives, or that the epoch of collection was not the most suitable. According to the biometric indexes that were registered we find that bigger congompes in size and weight they correspond to Shucshuyacu's zone, and in average they are major that the registered ones for the same species in Loreto. With regard to the pucashimi the zone that brought major indexes in size and weight they correspond to the especimenes collected in Mamonaquihua's zone
