About this new genus, see under Pachychelium Davidis. *iii. Pachychelium Davidis n. sp. (Fig. 35). Occurrence. The "Ingolf" has secured a single specimen of this very easily recognizable species at one Station W. of Greenland: St. 27: 64°54'N., 55°io' W. 740 m., temp. 1 spec. mm. Description. Length mm. The specimen is perhaps not mature; sex cannot be given with certainty, for there are neither calceoli nor marsupial plates. The body has a rather slender appearance, which is especially due to the rather small coxal plates. The back is evenly rounded. Cephalou abt. as long as 1. mesosome segment; lateral lobes rather long and narrow, rounded in. Fig- 35. Pachychelium Davidis. the apex. No traces of eyes could be found. The two pairs of antennae are of equal length. Ant. 1 extremely heavy, abt. 21/., time as long as the head; 1. joint of peduncle abt. as long as broad, as long as the two next joints combined.
