Part of the problem in distinguishing between these two species lies in the disparate sizes. Almost all our specimens of B. sulcatus are small whereas nearly all our specimens of B. vanhoepeni are large. Very few specimens of both species are of equal size for comparison. Small specimens of B. van- hoepeni, Figure 109H, show lateral ornament comparable to that of typical forms of B. sulcatus, but none shows as strong ventral or dorsal ribbing as in typical B. sulcatus. Adult forms are easily distinguished: B. vanhoepeni has typical widely spaced, auricular, lateral tubercles and grows to much larger size than any known B. sulcatus. Lateral ornament in typical B. vanhoepeni is very similar to that of ?late B. sulcatus, but again, none of these late forms of.
