8. E. RUFIBRANCHIALIS, Johnston. 



E. rufibranchialis, Johnst. in Loud. Mag. N. H. v. p. 428 ; A. & IL Brit. 

 Nud. Moll. fam. 3, pi. 14. 



BODY very slender, tapering to an elongated and finely 

 pointed tail, white : dorsal tentacles linear, of moderate length, 

 slightly corrugated : oral tentacles a very little shorter than 

 the dorsal pair : branchial processes linear, rosecoloured, with 

 white tips ; set in 6 or 7 clusters on each side of the back : 

 foot with the anterior angles rather short. L. 1. 



HABITAT : Near low-water mark, on most parts of our coast, 

 but more especially in the east; not rare. It is difficult to 

 give exact localities, as other species have occasionally been 

 taken for it. [Kiel Bay and Little Belt (Meyer and Mobius).]
