The collection of " Sea-spiders " from the marine area included in the Clare 

 Island Survey's field of work comprises only eight species, most of which are 

 common and widespread around the Irish coasts. The specimens were mostly 

 collected by officers of the Fisheries Branch of the Department of Agriculture, 

 to whom I am indebted for the opportunity of publishing the results now 

 given. The area extends from Blacksod Bay in the north to BallynakiU 

 Harbour in the south. There can be little doubt that all the Pycnogons taken 

 might be expected to inhabit any suitable localities throughout the district ; 

 but it may be of interest to enumerate the species that have, so far, been 

 found in the various centres of observation.
