The two juvenal syntypes (5.2 and 6.1 cm. in plastral length) from Williamson County, Texas, are both catalogued as MCZ 1627, but only one of these bears a catalogue number. The two softshells are not _emoryi_, and are more nearly like _T. s. guadalupensis_ than _T. s. pallidus_. Actually, they are from an area of intergradation between those subspecies (see comments concerning intergradation under the accounts of the subspecies _pallidus_ and _guadalupensis_). White spots occur on the carapaces anteriorly and posteriorly, the larger (more posterior) of which are encircled with dusky ocelli. The carapace of the small specimen (bearing no number) is brown having a few, small black specks intermixed with the white spots. The carapace of the large specimen is pale lavender and has a more obscure pattern than the other specimen. After Agassiz's description, _emoryi_ was accepted as a distinct species. Neill (1951:15) suggested that _emoryi_ was subspecifically related to _T. ferox_. Crenshaw and Hopkins (1955) and Schwartz (1956), however, demonstrated that _ferox_ was a distinct species; _emoryi_ has since been considered a subspecies of _T. spinifer_. Two specimens having blackish dots on the carapace, indicate relationship with _T. s. guadalupensis_. USNM 7638, a hatchling, has large whitish dots surrounded by blackish dots confined to the posterior half of the carapace, and the locality for this specimen is merely Río Bravo (= Río Grande). CNHM 47366, a hatchling from Sierra de las Palmas (Sierra de Santa Rosa, La Palma), Coahuila, has a few, small, blackish dots, irregularly spaced, on the anterior half of the carapace, but other dots more evenly distributed on the posterior half where they are intermixed with whitish dots. The drawing of the dorsal view of a hatchling _emoryi_ (Agassiz, 1857:Pl. 6, Fig. 4) shows a sprinkling of blackish dots on the anterior half of the carapace. A hatchling from Eagle Pass (USNM 116578) does not have a noticeably widened pale rim posteriorly on the carapace, and is not distinguishable from _pallidus_. See account of _T. s. guadalupensis_ for further comments on intergradation.
