Head, 30 fathoms. Here there are sand to the north and mud to the 

 south, and some hauls were taken along the line of junction. Amongst 

 other things the following nudibranchs were obtained : Tritonia 

 Hombe7'C/i, Dendronotus arhorescens (up to 5 inches in length), Eolis Druvi- 

 viondi, Eolis rufihranchialis, and Eolis Farrani ; also Virgularia mirabilis 

 and no less than twenty-five species of hydroid zoophytes and twenty- 

 three species of polyzoa. 



V. From March 29 to April 4 the Committee were working from 

 Port Erin, and had the s.s. ' Lady Loch ' hired for two of these days. 

 One day was spent in dredging on the rocky bottom round the Calf and 

 near the Chicken lighthouse, and in exploring the caves about Spanish 

 Head and the Stack Rock. These can only be entered in a boat in calm 

 weather at low tide. Their sides and roof are so closely covered with 

 masses of bright red ascidians {Fohjcarpa glomerata), black and white 

 sponges (Pachymatisma Johnstoni and Stelleita GolUiigsi), and tufts of 

 Tuhularia indivisa that scarcely any rock is visible. Amongst the more 

 noteworthy animals dredged round the Calf and obtained on the neigh- 

 bouring shores were the rare calcareous sponge Ute glabra, Corynadis 

 viridis, Hyalinoecia sp., Depastrum cyathiforme, Lineus gesserensis, Dinophilus 

 tmniatus (breeding at Easter), fifteen species of hydroids, including 

 Aglaophenia tubulifera, Halecium tenelluni, Lafoea dumosa form robvMa, L. 

 fruticosa, Cuspidella costata and G. humilis ; the brachiopod Crania anomala ; 

 the Crustacea Xantitu hydrophilus var. tuberculatus, Ebalia tuberosa and E. 

 tnmefacta, Oalathea dispersa {one with, a parasitic Bopyrian), Spirontocaris 

 spinus (one with a parasitic Bopyrian), Janira maculosa, Tritceta gibhosa, 

 AmphitJioe rubricata, Aora gracilis, Conilera cylindracea, Mcera Othonis, 

 Metopa (? n. sp.), and others ; the mollnsca Spirialis retroversus, Bissoa, 

 cingulus, var. rupesiris, Fissurella grceca, Emarginula Jissnra, Chiton Icevis, 

 Pleurobranchus plumula, Lima elliptica and L. Loscombii, Astarte sulcata 

 and A. triangidaris, Solecurtus antiquatus,Lyo7isianorvegica,Pectentigrinus 

 and P. testce, Kellia suborbicularis. Pandora incequivalvis, Lamellaria 

 perspicua, Circe minima and Thracia disiorta, the two last being new 

 records to the district ; the tunicata Molgula citrina, Styela grossularia, 

 Ascidia venosa, A. virginea, and A. pilebeia, Botrylhis Schlosseri, B. violaceus, 

 B. smaragdus, Distomum rubriim, Amaroucium proliferiim, A. argus, 

 Leptoclimnn maculaium, and Didemnum gelatinosum, Botrylloides rubrum, 

 B. Leachii, B. albicans ; and the polyzoa Chorizopora Brogniartii, Cylin- 

 droscium dilatattim, Smittia trispinosa,, Biastopora suborbicularis, ^tea 

 recta, and Alcyonidium mamillatum, which is new to the district. 



YI. April 28 to May 1. During two of these days the Committee 

 had the use of the Lancashire sea-fisheries steamer ' John Fell.' On 

 one day dredging was carried on in shallow water along the shore about 

 Fleshwick Bay, to the north of Port Erin ; while on the other day 

 advantage was taken of the fine weather to run out to the deep water 

 halfway to Ireland and work inwards. Hauls were taken at the 

 following localities : — 



1. Fourteen miles north-west of Port Erin, 70 fathoms, mud : Found 

 Calocaris Macandrea, Lipobranchius Jeffreysii, Bissoa abyssicola, Nucula 

 sulcata, &c. 



2. Ten miles north-west of Port Erin, 50 fathoms, mud : Found Briss- 

 opsis lyrifera, &c.
