Report 071 the Marine Fauna of S. W. of Ireland. 621 



It is quite certain that in Berehaven specimens of Ocnus, 

 coloured brown or white, are found living together. I, at any 

 rate, am unable to detect any difference between them : it appears 

 to me, therefore, that 0. brunneus may well be regarded as a 

 synonym of 0. lacteus. 



Also from Berehaven was found an Ocnus of elongated form : 

 as it is represented by a single specimen, it is as well to suspend 

 judgment as to its exact affinities. 



Synapta inhserens, 0. F. Miill. Berehaven, 10 fathoms. 



Vermes. 



TUEBELLAEIA. 



Eurylepta cornuta, 0. F. Miill. Shore, Dunboy, Berehaven. E. 

 vittata, Mont. Berehaven, 10 fathoms ; one large specimen ; and other 

 unnamed " Planarians." 



IS'emeetea. 



Amphiporuspulcher (?) Johnst. Berehaven ; 10 fathoms. IS'emertes 

 neesii, (Erst. Shore, Dunboy ; numerous. Lineus marinus, Mont. 

 Berehaven and Bantry Harbour. A large, very brittle, whitish jSTe- 

 mertean, with a pinkish head, was dredged at Stations III. and VI. ; 

 it is probably Cerebratulus angulatus, 0. E. Miill. The anterior por- 

 tion of a Nemertean was dredged in Berehaven ; it probably belongs 

 to the genus Micrura. It was 35 mm. long, and 2 mm. broad ; flat- 

 tened, head slightly swollen, gradually tapering anteriorly ; trunk of 

 body produced on the sides into a thin band, really forming a continuous 

 lateral fin ; no eyes were detected ; a large lateral cephalic groove, dis- 

 tinctly red at the wide posterior end ; colour dull pale, creamy orange, 

 irregularly sprinkled with burnt sienna spots, which are more nume- 

 rous at the anterior end ; cephalic ganglia shine through with a marked 

 rosy colour. If this species should prove to be new, the specific name 

 of Pardalis would be appropriate for it. Carinella annulata, Mont., 

 Berehaven.
