We present the first species list of squamate reptiles of the municipality of Barcarena and surroundings, in state of Pará, north of Brazil. The study area is dominated by secondary florest at different successional stages. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and inventories of the herpetofauna conducted in the Barcarena region. This list comprises 17 families (Amphisbaenia: Amphisbaenidae; Sauria: Gekkonidae, Gymnophthalmidae, Iguanidae, Phyllodactylidae, Polychrotidae, Scincidae, Sphaerodactylidae, Teiidae, Tropiduridae; Serpentes: Aniliidae, Boidae, Colubridae, Dipsadidae, Elapidae, Typhlopidae and Viperidae), 44 genera and 59 species of squamate reptiles.

We present the first lizard species list for the municipality of Juruti, state of Pará, Brazil. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and from inventories conducted in 2008-2011. Sampling methods included pitfall traps with drift fences and time constrained searches. We considered the data collected by other researchers, incidental encounters and records of dead individuals on the road. We recorded 33 species, 26 genera and ten families. Norops tandai was the most abundant species. Compared with the other regions of Amazonia, the region of Juruti presented a large number of lizards. However, further studies with an increase in the sampling effort, could prove this area to be richer in lizards than that observed so far.
