_Natural and experimental prey._--_Pycnoscelus surinamensis_, Cuba (Darlington, 1938): This species was eaten both in captivity and in nature. The lizard ate most readily soft, immature cockroaches. _Pycnoscelus surinamensis_ is probably a staple food of the lizard in nature, as Darlington observed wild lizards catch the nymphs. =Anolis stratulus= Cope _Natural prey._--_Aglaopteryx facies_, Puerto Rico (Wolcott, 1924): One cockroach was found in 50 lizards examined. Cockroach, Puerto Rico (Schmidt, 1920): One of 25 stomachs contained a cockroach. =Anolis= sp. _Natural prey._--"Wood roaches," British Guiana (Beebe, 1925a): The above lizard is arboreal on foliage in low jungle. Family SCINCIDAE =Leiolopisma laterale= Say _Common name._--Brown skink. _Natural prey._--Woodroaches, U.S.A., Louisiana (Slater, 1949): Analysis of stomach contents of 84 adult skinks showed that nymphal and adult woodroaches comprised the majority of Orthoptera. =Tropidophorus grayi= Günther _Common name._--Spiny lizard. _Natural prey._--Cockroaches, Philippine Islands, Laguna (Villadolid, 1934): Food of this species was mostly Blattidae. =Unidentified skinks= _Natural prey._--Cockroaches, Arno Atoll (Usinger and La Rivers, 1953). Family AGAMIDAE _Experimental prey?_--Cockroaches, Australia (Lee and Mackerras, 1955): A general statement was made that in captivity Agamidae were observed feeding avidly on cockroaches and other insects. Three agamids studied by these workers were _Amphibolurus barbatus_ (Gray), _Physignathus lesueurii_ Gray, and _Chlamydosaurus kingii_ Gray. Family CHAMAELEONTIDAE =Chamaeleon chamaeleon= (Linnaeus) and =Chamaeleon oustaleti= Mocquard _Experimental prey._--Cockroaches, Amsterdam (Portielje, 1914): Large cockroaches were fed to these lizards in the reptile house of Artis. Family TEIIDAE =Ameiva exsul= Cope _Common name._--Iguana, ground lizard. _Natural prey._--Cockroach (nymph), _Epilampra wheeleri_, and _Periplaneta americana_, Puerto Rico (Wolcott, 1924): Stomach contents of 15 lizards were analyzed. _E. wheeleri_ formed 30 percent of the food of one lizard. The cockroach nymph formed 5 percent of the food of one lizard. One _P. americana_ formed 20 percent of the food of one lizard; another formed 50 percent of the food of a second lizard. _Experimental prey._--Cockroach nymphs, Puerto Rico (Wolcott, 1924). =Ameiva= sp. _Natural prey._--Cockroaches, British Guiana (Beebe, 1925a): The above lizard is terrestrial and found near clearings. The stomach contents of 18 out of 40 reptiles contained cockroach remains. =Cnemidophorus= sp. _Natural prey._--Cockroaches, British Guiana (Beebe, 1925a): This is a terrestrial lizard found near clearings. The stomach contents of 4 out of 40 lizards contained cockroaches. =Unidentified lizards= _Natural prey._--Cockroaches, West Indies (H., 1800). _Experimental prey._--_Blatta orientalis_, U.S.A. (Rau, 1924): Rau called the predator a common gray lizard.
