CaRPENTER—On some Pycnogonida fromthe Irish Coasts. 208 
and Wilson (17, 18) notes specimens from the east coast of North 
America from more than three times that depth. 
The specimens which I have examined, obtained in March and 
April, are all immature, while those taken in June, July, and 
August, are nearly all adult. The egg-mass carried by the male 
is circular, like a cushion, and nearly as large as the animal itself. 
My best thanks are due to Prof. Haddon and to the collectors 
mentioned above, who have kindly supplied me with the spe- 
cimens; and I am specially indebted for the generous help 
afforded me by Prof. D’Arcy Thompson in giving and lending 
me specimens for comparison. This paper must be regarded as 
but a preliminary record on the subject; and it is to be hoped 
that systematic work, specially around our northern coasts, may 
largely increase the knowledge of Irish Pycnogonida.
