by Mr. Ascroft, taken by him in low water marine pools 

 at Lytham. It is evident that a considerable amount of 

 fresh-water finds its way into the Lytham pools. 



Cyclops ewarti, Brady. 



This species, first taken in the Forth estuary, was 

 suspected by Brady to have a fresh-water origin. Ours 

 are evidently strictly marine, two specimens, both males, 

 having been dredged at 20 fathoms off Port Erin. 



Family Haepacticid^. 



Longipedia minor, T. & A. Scott. 



A few specimens of this species were collected by hand- 

 net in the rock-pools at Hilbre Islands in March, by 

 Mr. A. Scott. It is easily distinguished from L. coronata, 

 Glaus, by its much smaller size. 



Ganuella perplexa, T. & A. Scott. 



Frequently found in dredged material taken about Port 

 Erin. It has probably been overlooked from its general 

 resemblance to Longipedia coronata, the points of differ- 

 ence being enumerated by Scott. 



Ectinosoma. normaiii, T. & A. Scott. 



Several specimens were obtained by Mr. A. Scott in 

 material from Barrow Channel, collected in May by 

 Professor Herdman, and I have also dredged it off Port 

 Erin. When fresh this species has a brilliant red spot 

 on the lower angles of the cephalothorax, and in this 

 respect it agrees with E. erythrops, Brady. 



Ectinosoma elongata, A. & T. Scott. 



One specimen was found in material from pools at 

 Hilbre Island. 



Ectinosoma gracile, T. & A. Scott. 



One or two specimens of this species were obtained 

 among dredged material collected at Port Erin by 

 Professor Herdman. -
