Black not shining; the lower part of the face angularly produced in 

 front; the hinder part of the head deeply emarginate, the posterior angles 

 acute ; the antennae black, with the basal joint scarcely longer than the 

 second ; wings hyaline, with a blackish very narrow stigma, the stigmal 

 nerve running nearly to the tip of the wing; legs dirty testaceous; the 

 entire coxae and thighs (except at the base and tips) pitchy black, the 

 hinder legs the darkest. - [j jsnibirtignoi

15. Plumula^ria Cathari^nj. (Jig. 61.) 

 A specimen of this feather coralline, so large and perfect 

 as that selected for the present illustration, rarely occurs ; but 

 smaller specimens are not uncommon in Berwick Bay; and 

 I have seen the same from the Frith of Forth, in the collec- 

 tion of my friend Dr. Coldstream of Leith. It has been 

 hitherto confounded with the Plumularia pinnata or setacea 

 of Lamarck, which have the same outward habit, and rival it 

 in delicacy and beauty; but the minuter characters are so 

 dissimilar, that no doubt can be entertained of the distinct- 

 ness of these species from one another. 



Dr. Fleming, in his History of British Animals, has reduced 

 PL pinnata and setacea to one species ; and I adopted this 

 opinion in my catalogue of the zoophytes of North Durham, 

 published in the Transactions of the Natural History Society 

 of Newcastle [and noticed in this Magazine, Vol. V. p. 702.]. 

 I am now satisfied that, in so doing, I was in error ; and, with 

 a view of correcting this error, but more especially of point- 

 ing out with greater precision the distinctions between the 

 species under consideration, I will here subjoin their cha* 

 meters : —
