. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. 372 BULLETIN OF THE hind. Telson entire, with a seta on each side of the hind margin. Pedun- cle of first antenna about as long as the head and first two thoracic seg- ments together; flagellum composed of fifteen segments. Basal joint of second antenna distinct; olfactory denticle prominent; distal segment of peduncle much longer than the antecedent segment; ilagelluin longer than the flagellum of first antenna, composed of fifteen segments. Propodite of second pair of legs in the male large and swollen; palmary edge sinuous and very long, encroaching upon the lower margin, armed with seta1; lower mar- gin of propodite short; inferior angle of carpopodite produced between the meropodite and propodite. In the female, as usual in the genus, the second pair of legs are weak, the propodite not larger than the meropodite,'the palm making nearly a right angle with the lower margin. Seventh abdom- inal legs, when extended backward, reach the end of the caudal stylets. The shell, seen under a high magnifying power, is furnished with small scat- tered hairs, with here and there one of those cross-shaped figure s seen in the integument of so many of the Orcliestidos. Length of body 9mm to 13mm About two dozen individuals of this species were taken in the lake ; the ex- act locality is not preserved, nor the depth of water. It is closely related to the preceding species, but may be easily distinguished from it by the hand of the second pair of legs. Allorchestes cupreus, sp. nov. Fir.
