REPORT ON THE PYCNOGONIDA. 229 



rocky pools at Hilbre, New Brighton, &c. That may have 

 been so in 1855, but it is certainly not the case now. How- 

 ever, it is really very doubtful what species was meant by 

 Nymphon gracile, as that name has been applied by natural- 

 ists to a number of the commoner species of Nymphonidae 

 and the allied families indiscriminately. 



Under this species may be placed provisionally some 

 specimens obtained both off the south end of the Isle of Man 

 (fifteen fathoms) and also off Pufi&n Island (eleven to thirteen 

 fathoms), which show some of the characteristics of Peph- 

 redo hirsuta, a species described briefly by H. Goodsir in 

 1842. Goodsir's specimen was from the Isle of Man, but it 

 has not been found since, and its position and relations are 

 still very uncertain. The Liverpool Bay specimens appear to 

 have more than three joints in the palpus, and therefore ought 

 not to belong to the genus Pephredo. The examination of 

 more material from this neighbourhood is much to be de- 

 sired, as it may result in the clearing away of the existing 

 doubts as to Mr. Goodsir's species.

One example of this Pycnogonid was obtained during the 

 cruise of the ** Hyaena," on 24th May, 1885. It has all the 

 characteristics of Hodge's description. The species has 

 previously been found at the Isle of Man, as well as at a few 

 other points on the English coast.
