Type. The lectotype is USNM 73296, the original of Reeside (1927, pl. 6, figs 5-6), by subsequent designation of Cobban and Kennedy (1992a, p. 449). It comes from the Elk Basin Sandstone Member of the Telegraph Creek Formation, Wyoming, USA.

Material. Four specimens, CPC –2604 to –2607, from beds TPY52, 57, and 77 .

Description. Compressed whorl section with rounded dorsum and venter. The shell is smooth or ornamented by faint bullae and falcate ribs in dorsolateral position.

Remarks. Our specimens are deformed. Their characteristics correspond to the lectotype of Reeside (1927, pl. 6, figures 5-6) with respect to whorl section, as far as reconstructible, and the faint ornament. The suture is little incised. Superficially, B. haresi Reeside, 1927 resembles B. scotti Cobban, 1958 and B. eliasi Cobban, 1958 , but the latter two species differ in the shape and higher complexity of their sutural elements.

Occurrence. Baculites haresi is widely distributed in lower Campanian strata of the Western Interior Seaway, from Wyoming to Texas ( Larson et al., 1997), and also present in Coahuila ( Ifrim et al., 2013, and herein). Isolated records also exist from the lower Campanian of New Jersey (fide Klinger and Kennedy, 2001) and Greenland ( Birkelund, 1965).
