A HISTORY OF SUSSEX 



Upon either side of these and arising from 

 the body are four or five erect, linear 

 processes. The dorsal tentacles are lamin- 

 ated in the upper half, that portion being 

 bent backwards. From near the base of 

 each tentacle are given off two narrow arms 

 directed forwards ; and upon either side of 

 the lip there is a tentacular process. All of 

 these appendages are more or less tipped 

 with orange or yellow, besides which there 

 is a line down the tail of the same colour. 

 This species is very beautiful when under 

 full sail in its proper element, but when 

 seen upon the rocks at low tide it appears 

 like a little shapeless ball of jelly quite 

 unlikely to attract attention. It is usually 

 found in moderate profusion. Hastings.

192. Moschites cirrosa, Lamarck. 



Upon the authority of Mr. W. Wells of 

 the Brighton Aquarium this species occurs 

 off that town. It is peculiar for having a 

 single row of suckers along each arm.

 ASCIDIAD^ 



1. Ascidia mentula, O. F. Muller. 



Test semi-opaque, rather coarse, of a 

 faint yellowish flesh colour ; height, about 

 2 inches. Branchial aperture with eight 

 lobes, and both apertures coloured bright 

 crimson or with bright red spots. The 

 test often has embedded in its exterior 

 coralline stems, polyzoa, etc., and inter- 

 nally harbours the mollusc Modiolaria 

 marmorata. Common in the trawl and 

 sometimes cast ashore. Hastings. 



2. Ascidia virginea, O. F. Muller. 



Test transparent, smooth, colourless ; 

 height i\ inches. Specimens often en- 

 folded in the branches of corallines, the 

 test sometimes extending a short way up the 

 stems. Branchial aperture eight-lobed. 

 Often harbours Modiolaria marmorata. 

 Not uncommon ; trawled. Hastings. 



3. Ascidia vitrea.f 



Brighton. 



4. Ascidia, sp. 



Upon the shore at extreme low water, are 

 often found extensive beds of an Ascidia, 

 packed closely together. The test is 

 coated with sand and is oblong to sub- 

 globular in form ; length of a specimen 

 about I inch. Branchial orifice appears to 

 be four-lobed, but the lobes are probably 

 subdivided ; about four short tentacles are 

 seen. Common. Hastings. 



5. Ascidia, sp. 



There is a species, somewhat resembling 

 the last mentioned, occurring upon coral- 

 lines. It is smaller, measuring about ^ 

 inch in diameter, rather depressed, and 

 coated with sand. Lobes of the branchial 

 orifice as in the foregoing species. Com- 

 mon. Hastings. 



6. (?) Molgula arenosa. Alder and Hancock. 

 Animal nearly globular, barely J inch in 



diameter ; coated with fine sand ; branchial 

 orifice six-lobcd. Specimen has been 

 apparently slightly attached. Tubular 

 character of orifice non-apparent. Hast- 

 ings.
