Geographical Distribution. 
* Porcupine ’ Expedition o/1869. — Carpenteb, 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 Fseroes, and 
Shetland) : — Cidaris papillata^ Echinus elegans^ Spatangus raschiy Brisinga 
endecacnemos, off the west of Ireland j Pourtalesin miranda^ S.E. from 
Rockall ; Ophiocten hrceyeri, Ophiothrix fragilis^ Amphiura halliy Ophiacantha 
spinulosa, off the S.W. extremity of Ireland; Asteronyx loveni, N.W. of He- 
brides 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. II. Soc. 
Dec. 8, 1870) as taken in the ^ Porcupine ’ Expedition of 1870, off the 
French, Spanish, and Portuguese coasts, and in the Mediterranean. 
Metzger {1. c.) records the following Echinodermata from the 
East- Frisian coast, the investigation of which, owing to its topo- 
graphical peculiarities, is accompanied with very considerable 
difficulties : — 
Asteracanthion ruhenSy M. & T. ; Solaster papposa, Forbes ; Ophiura textu- 
rata, Lmk. ; Amphiura neglecta, Forbes ; Ophiothrix fragilis, Miill. ; Spa- 
tangus purpureus, Miill. ; Echinocardium cordatum, Penn. ; Echinocyamus 
pusillus, Miill. ; Psammechinus miliaris, Leske ; Sphcerechinus escidentus, L. 
Crinoidea.

nesian Islands. Twenty-four species were found by the author 
himself in the Indian archipelago ; and of these the following 
are new : —
