moving altogether ; but when the animal was 

 touched, the legs began again to move irregularly 

 and more languidly. At 36 minutes they stopped 

 for about a minute, and again commenced to give 

 an occasional stroke or two. At 40 minutes the 

 only motion, which was very weak, was confined to 

 one of the swimming feet. At 45 minutes all motion 

 had ceased. Another of the same species, when 

 exposed to the same treatment, lived for 40 minutes, 

 and another for 35 minutes, both going through 

 nearly the same symptoms. When in confinement, if 

 a little weed or such other material is in the water 

 with them, it is difficult to get them away from it, 

 as they make every effort against being dislodged. 



One that was dislodged with its nest from the 

 side of a stone was put into a basin of water ; in a 

 few days it had the nest firmly attached to the 

 basin. Like many of their congeners, they carry 

 their young under their body, but these are not 

 readily seen in life. Spence Bate and West wood, 

 Brit. Sessile-eyed Crust., vol. i., p. 422, state that the 

 eyes are black ; but all those that I have examined 

 are red, apparently with a white net- work or areole 

 over the red, although by transmitted light they 

 appear dark. 



I have taken this species among the roots of 

 Laminaria saccharina near the Tan Buoy, in 6 to 7 

 fathoms water, and by the dip-net among Halidrys 

 siliquosa, Cumbrae. Bate and Westwood (I.e., vol. 

 i., ]>. 424) record it from Skye ; Moray Firth ; the 

 Outer Skerries Harbour, Shetland; amongst confervse 

 in pools left by the tide near Berwick; Plymouth, 

 between tide-mark ; Co. Clare, Ireland ; the coast of 

 Normandy ; and from Hummock's Island, Bass's 

 Straits, and the Crimea.
