Amaral (1935) described the new genus and species Calamodon paucidens based upon one specimen collected at 'vila Sao Simao', municipality of Cacequi (29" 53' S: 54" 49' W), state of Rio Grande do Sul (RS), Brazil. The name Calamodon was preoccupied, being replaced by Calamodontophys (AmaraI,1963).Asociación Herpetológica Argentina (AHA

This paper reports meri stic and morphome-
tri c vari ation of all known specimens (including 
10 reponed here in for the first lime) of Cala-
1110dOllfOphis paucidens (tab. 1). Of the ten new 
spec imens, nine are fro m the municipality 01' 
Cachoeira do Sul, RS (30" 02 ' S; 52" 54 ' W ), 
and one is from the Department ol' Trein ta y 
Tres. U ruguay (320 56' S ; 540 26' W) (fig. 1). 
AII specimens from Ri o Grande do Sul were 
co llected in localities situated in lhe Depressao 
Central, between the Planalto Sul-Rio-Granden-
se (o r Serra do Sudeste) and the south slopes 
ofthe Pl analto Meridional ol" Brazil. Thi s region 
was originally covered by grass lands (Savana) 
in open areas, with deciduous and semideciduo-
us seasonal forests covering the slopes of the 
adjacent plateaus (IBGE, 1986). 
Although thi s note reporls several new 10-
ca lity records , the avai lab le data are still insu-
ffic ient to characterize the habitat 01" the spe-
cies. The Uruguayan specimen was co llected 
in an open grassy area; the specimens MCP 
5737,7590, 7834,8773 and 11469 were found 
in very di sturbed areas, such as ga rdens of 
houses and monocultures of pecan trees (Ca r-
ya illinoensis), in Cachoeira do Su!' 
Some specimens showed defensive beha-
viors at the time of capture and during their first 
few days in captivity. When handled, fo ur in-
dividual s (MCP 5737, 7590, 7834 and 8607) 
coi led the body and hid the head among the coi ls 
(fig. 2). Two individual s (MCP 5737 and ZVC-
R 5500) opened the mouth , exhibited the dark 
ora l mucosa, and performed false strikes (see 
Greene, 1988). The specimen MCP 7590 com-
pressed its body dorsoventrally (fig. 3).
