238 Dr. K. Koehler on the Littoral Fauna of the 



quits a certain depth, and is common in St. Aubin's Bay, 

 attaclied to the shells of Buccinum in which EujKigurus Pri- 

 ieauxii resides. 



ECHINODERMATA. 



This is one of the worst represented divisions at Jersey ; at 

 least the specimens that one can find on the shore are few in 

 number and belong to but slightly varied types. Thus I 

 have never met with a single Echinid, and Mr. Sinel told me 

 he had never met with any, even at the time of the highest 

 tides. But with the dredge, in St. Aubin's Bay, some ex- 

 amples of Strongylocentrotus UviduSy Brandt, and Sphccr- 

 echinus granularisj Ag., may be captured. One day, with a 

 high tide, Mr. Sinel found a Sjyatangus jmrpureuSj Miill., at 

 La Bocque. It is to be supposed that this animal was thrown 

 up upon the shore by the waves. 



OjpMothrixfragilisy Miill., and OpMocoma neglecta^ Johnst., 

 are very common. I have obtained in considerable abundance 

 with the dredge, in St. Aubin's Bay, OpMura alhida, Forbes, 

 in association with a few specimens of 0. texturata^ Lara. 



Asteriscus verruculatus ^ Betz., is very common everywhere ; 

 Asterias glacialis, Miill., is much less common on the shore ; 

 but with the dredge one may collect some interesting species 

 in St. Aubin's Bay — Pahnipes memhra7iaceus, Betz., Solaster 

 j^ajyposiiSy Eetz., Asterias ruhens, Linn. I may also cite 

 Cribrella occulata, Penn., of which 1 found several specimens 

 at La Mothe. 



The Comatulse are very rare on the coast, but not altogether 

 wanting ; they may be found at the Dog-Nest and at different 

 parts of the Gr^ve d'Azette. 



Sgnaptce {S. rn/iarens, Diib. & Kor.) are common in 

 the vicinity of Elizabeth Castle. Of the Holotlmrians I 

 have not met with a single species during my two visits. 

 Mr. Sinel once captured at La Bocque a specimen of Gucumarm 

 which has not been determined. 



Veemes. 



I shall consider first the Turbellaria and then the Poly- 

 cliseta. 



Turbellaria. 



Of the Planaria3 the commonest species is LejJtopleura tre- 

 inellaris^ Q^rst., which is found adhering to the lower surface 

 of stones, especially on the Greve d'Azette. A very elegant 

 species which is sometimes associated with it, and which is also 

 observed among the Zostcrw^ is Prosthcccrccus vittatus, Lang. 

 Polycdis lavigatus, Quatref., is often met with among the
