Sir, 

 I SHALL feel gratified if the accompanying contributions to 

 the British Fauna, " a very short paper and very long draw- 

 Hngs," should meet with your approval, and obtain a place in 

 your journal. Believing that natural history will, in this 

 country, he. much more advanced by presenting accurate 

 sketches of its objects, than by the most voluminous descrip^ 

 tions unaided by them, I shall, confident in the attention I 

 pay to the delineation of those I forward, continue to supply 

 you, from time to time, with such of the animals I meet with 

 as appear to me totally new. I am. Sir, yours, &c.

Asci'dia? ge'jmi"NA. {Jig.^Ai.a) — Body coriaceous, elongate, 

 cylindric, adhering to the rocks by 5 or 6 roots, of a greenish 

 brown colour, surmounted superiorly by two mammiform pro- 

 cesses {b\ each with a terminal orifice {c) surrounded by 5 oval 

 orange marks. These processes are retractile, but easily made 

 to protrude by pressing the body ; and, on continuing it, water 

 is projected in jets from both orifices. It adheres very strongly 

 to the rocks, a number of them being generally found within 

 the limit of a few inches.
