Fig. 32. 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.
