NOTES ON THE FAUNA OF THE ISLE OP MAN. 323 



at a short distance from the shore, on a bottom composed of 

 stones and sea- weed and dead shells, the following animals 

 were found to be abundant : — Antennularia ramosa, Plumu- 

 laria pinnata, Antedon rosaceuSy Echinocyamus pusillus, 

 Pectinaria belgica, Terehella nebulosa, Galathea intermedia y 

 Stenorhynchus rostratuSj Pectuncidus glycimeris, Velutina 

 Icevigata, Trochus magus, Aplysia punctata^ MorcheUlum 

 argus, Clavelina lepadiformisj Ciona intestinalis, Corella 

 parallelogramma, Styela grossulai'ia, Eugyra glutinans, 

 and Molgula occulta. 



The following rarer forms were obtained once or twice in 

 the same locality : — Halisarca dujardinii, Halcampa chry- 

 santhellum, Thyone papillosa, Cucumaria hyndmanni, Her- 

 madion assimile (on the peristome of Echinus esculentus), 

 Hermione hystrix, Carinella lineata, Amathia lendigera, 

 Crangon scidptus, Ebalia cranchii and E. tuherosa, Inachus 

 dorsettensis, Trivia europcea, Doto fragilis, Eolis picta, 

 Eolis amoena, Eolis lineata, Polycyclus savignii, Polycarpa 

 monensisy n.sp. 



The tow-net was used on most days, generally in the 

 neighbourhood of Port Erin. On some few days, when it 

 was too rough to dredge, it was possible to work the tow-net 

 in the more sheltered parts of Port Erin Bay. Whenever 

 the tow-net gathering was at all good, or seemed to shew any 

 peculiar organisms, it was preserved in the following manner 

 for future examination : — The tow-net on being brought on 

 board was turned inside out into a wide-mouthed gallon jar 

 of sea water, in which the organisms could be roughly 

 examined with a pocket lens. A few grains of solid picric 

 acid was then added, so as to kill and precipitate the 

 organisms. A great difference was noticed in the amount of 

 picric acid which the different kinds of animals were able to 

 withstand. All the larvae, the Medusoid Gonophores, and 

 the Sagittse die first, while the Crustacea are still quite lively
