The body is very wide, as is also the head; the prebasilar segment of the latter is very strongly widened posteriorly. The mandibles have on the inner side one or two excessively minute denticulations. The anterior portion of the body is a dilute orange, but a short distance from the head a dark stripe commences, which, gradually widening, soon involves the whole surface in a very dark olive tint. The scuta are uneven and variously wrinkled. This form differs from the following in having the head very much broader, and the cephalic segment not emarginate anteriorly; the labium much more deeply canaliculate, and the number of segments not so great. Still it is possible that the differences are only sexual, and, having but one specimen of each, I cannot decide this point. The creature was caught near Philadelphia by my friend, Dr. Horn. I append a description of what may be the female of this species.

The sterno-episternal sutures are well marked, but not as deeply as the scuto-episcutal. The surface of most of the scuta is quite uneven, sometimes almost coarsely rugose. The dorsum has a very indistinct dark median stripe, more apparent on the posterior portion. Length, 1¾ inches.
