The form of the body, shape of the carapace and of the telson, marginal position of the eyes, the relative proportions of the somites, and details in the appendages, all point to affinities with Hughmilleria socialis Sarle, from the Pittsford (figs. 26, 27). Such a relationship seems a little disconcerting at first, in view of the fact that the Pittsford sediments and fauna came from Appalachia, while the Ludlow was a derivative from Atlantica and should have a fauna essentially distinct from the former. Indeed, with the excep- tion of this one species, the members of the Ludlow fauna show no relationship to any species from the faunas of Appalachia. We have here, as a matter of fact, one of the " anomalies" of distribution.
