Chela of: a. Nymphon biarticulatum, Hodgson, holotype. b. N. mendosum, Hodgson, c. N. bouvieri, (."Ml :< 27.) The specimens from St. 167 have been provisionally referred to this species. The tarsus is nearly as long as the propodus— longer than is typical for A^^. brevicaudatutn —but the two terminal segments of the palp are consistently shorter than in either species (see Table V). Distribution. The holotype was collected in the Ross Sea area; with the exception of the specimens from Sts. 167 and 195 this form was collected beyond the southern range for N. brevicaudatutn.
