Barbour & Loveridge (1929:225) erroneously listed only MCZ 1597 and 1622 in the MCZ collection. Stejneger (1944:56–58) reported only two “co-types”, USNM 12349 and 37173, and considered MCZ 1597 and 1622 as paratypes . MCZ 1597 designated lectotype by Webb (1960:6) . Platypeltis agassizii Baur 1888:1121 Syntypes (2): MCZ 37172 , according to Stejneger (1944:72) and Schwartz (1956:9); and USNM 92584 (formerly MCZ 1601), according to Cochran (1961:233) ; however, Reynolds et al. (2007:3) did not consider the latter a type. MCZ 37172 considered holotype by Webb (1962 ; skull photographed therein, Pl. 54).
