Geographical Distribution.
' Porcupine' Expedition of 1869.—CAHPENTER, JEFFREYS, and WYVILLE
THOMSON record the occurrence of the following species in the area dredged
(extending from the west of Ireland to Rockall Bank, the Faeroes, and
Shetland):—Cidaris papillata, Echinus elegans, Spatangus raschi, Brisinga
endecacnemos, off the west of Ireland; PouHalesia miranda, S.E. from
Rockall; Ophiocten kreeyeri, Ophiothrix fragilis, Amphiura balli, Ophiacantha
spinulosa, off the S.W. extremity of Ireland; Asteronyx loveni, N.W. of Hebrides
and in the Minch. The " cold area " was found to be extraordinarily
rich in Echinoderms, mostly of a decidedly boreal or even arctic character
(e. g. Antedon eschrichti), while many of the southern types which presented
themselves were much reduced in size.
Various Echinoderms are also recorded by the same authors (P. R. Soc.
Dec. 8, 1870) as taken in the ' Porcupine' Expedition of 1870, off the
French, Spanish, and Portuguese coasts, and in the Mediterranean.
METZGER (I. c.) records the following Echinodermata from the
East-Frisian coast, the investigation of which, owing to its topographical
peculiarities, is accompanied with very considerable
difficulties:—
Asteracanthion rubens, M. & T.; Solaster papposa, Forbes ; Ophiura texturata,
Lmk.; Amphiura neglecta, Forbes; Ophiothrix fragilis, Mull.; Spatangus
purpureas, Miill.; Echinocardium cordatum, Penn.; Eehinocyamus
pusillus, Miill.; Psammechinus miliaris, Leske ; Sphcerechinus esoulentus, L.

OPHIUROIDEA.
VON MARTENS (Arch. f. Nat. pp. 245-260) gives a list of 63
