Apalone spinifera aspera ( Agassiz 1857:402, 405)

Syntypes (9, according to Webb 1960:3): MCZ 1597, 1622 (photographed in Stejneger 1944:Pl. 16), 37173, 46615, 46621 and 46633; and USNM 22676 (formerly USNM Osteo 12349), 248989 (formerly USNM Osteo 1084), and 248990 (formerly USNM Osteo 1086)( Reynolds et al. 2007:34). 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).

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).
