“Euvondrea floretta n.sp. (Figs. 2, 3)
Oral papillae 4; no genital scales; upper arm-plates twice as high as long; lateral arm-plates broadly contiguous below, but not above, each bearing 4 short, conical armspines on the distal, tumid margin, one placed alone, high on the plate, the other three together lower down; lower arm-plates twice as broad as long, triangular, with a distal base and an obtuse proximal apex, widely separated.
TYPE LOCALITY. N.Z. Oceanographic Institute Station A523, 5/2/1960, 73° 34' S., 175° 47' W. to 73° 31' S., 175° 34' W., 1,375 m, Pennell Bank, Ross Sea, J. S. Bullivant.
HOLOTYPE. In the collection of the N.Z. Oceanographic Institute, Wellington, R ca. 20 mm. r 4.5 mm. Colour in spirit, brown.
REMARKS. The extraordinary structure of the disc of this beautiful ophiuroid sets it apart from any known genus. The character of the arms, however, recalls two other Antarctic genera, Ophiurolepis and Ophiosteira. A similarity to Ophiurolepis tumescens Koehler is evident in the young stages of Euvondrea; these will be described in the official report of the expeditions. The name Euvondrea, which is to be treated as a feminine noun of the first declension, is formed by anagram from the name of the H.M.N.Z.S. Endeavour, by which all specimens were obtained.”
