On Floscularia trifidlobata, Sp. Nov. 



By Geo. M. Pittock, M.B., F.R.M.S., of Margate.

Plate I. 



Since the publication of Hudson and Gosse's great work on the 

 Rotifera, many new species have been discovered and recorded. 

 A list of new Rotifers found and described since that date (1889) 

 has been furnished by Mr. C. F. Rousselet ("Journal Royal 

 Microscopical Society," June, 1893). I have now to announce 

 the addition of another Floscule to the list of new species given in 

 Mr. Rousselet's catalogue. 



I will endeavour to follow his advice, that " when a new species 

 has been found, it should be figured and described in such a 

 manner that the animal may readily be recognized when found 

 again by a different observer, and a good figure is often worth 

 more than a good description." 



Any shortcomings in the following description will, I believe, 

 be made up by the beautiful and characteristic drawing which 

 accompanies this paper, for which I am indebted to my very kind 

 friend Mr. Dixon-Nuttall, whose accurate sketches from life of 

 many new forms are well known to many members of the Society. 



This small, but very distinct species, was discovered early this 

 year by my friend Mr. F. Daunou, of Margate, in hunting over 

 some water moss from the Minster Marshes, Thanet, a locality 

 which has already proved a very prolific hunting-ground to him 

 and to myself during the past summer. (See a short paper on 

 " Rotifer Hunting at Minster," in " Science Gossip," October, 

 1894.) At first sight this floscule somewhat resembles F. 

 longicaudata, in the length of the foot, and in the shape of the 

 long, pointed, dorsal lobe. Indeed, I sent a specimen to Mr. 

 Hood, of Dundee, for identification, in January last, believing it 

 to be an aberrant form of F. longicaudata.
