Turoucu the kindness of my friend Professor Haddon I have 
recently had the opportunity of examining the Pyecnogonida, 
dredged in 1890-91 by the “ Fingal” and “ Harlequin,” when 
engaged in surveying the West Coast fisheries under the auspices 
of the Royal Dublin Society. At his suggestion I now sub- 
mit a report on this material; and, through the courtesy of my 
chiefs, Drs. Ball and Scharff, I am enabled to add what may be 
learned from the specimens preserved in the Dublin Museum of 
Science and Art. Altogether I have examined eight species of 
these animals from our coasts, five of which are not in the list 
given by Thompson (1), which is, so far as I know, the only 
memoir on Irish Pyenogonida ever published. That list contains 
nine species,’ and I regret that I can only confirm three or four 
of them. Inquiry from Mr. 8. B. Stewart, Curator of the Belfast - 
Museum (to whom my best acknowledgments are due), has elicited 
the reply that Thompson’s specimens are not in that institution, 
and it is to be feared that they have not been preserved at all. Their 
discovery, if possible, is specially desirable, as half the species are 
referred to forms described by Goodsir, as to the identity of whose 
species the greatest doubt exists among recent workers at the 
group. Also, the great majority of these specimens were obtained 
from the north of Ireland, while the specimens which I have 
examined are all from Dublin Bay or from the west. The present 
list must therefore be regarded as representing but a small part of 
what we may hope to learn of the Irish Pyenogonida, when all 
our coasts have been adequately searched. 
' Munna Kroyert, Goods., which is not a pycnogon at all, but an isopod, appears in 
Thompson’s list by some strange error.
