4 DREDGING REPORTS. 



were taken three specimens of the Featherstar, Antedon rosaceus, 

 a very rarely noticed inhabitant of our shores, and here also a 

 remarkably fine hard of zoophytes was obtained ; but the species 

 were all, with one or two exceptions, such as were previously 

 known to inhabit our district. There was also in this locality an 

 astonishing abundance of one of the less common Brittle-stars, 

 Ophiocoma nigra. The Mollusca were very poor, the only species 

 new to the district being Chiton alius, L., of which a single speci- 

 men was dredged off Holy Island. Some of the sand-covered 

 Ascidians taken on the Durham coast require further examination. 

 We may hope that they will afford something of interest for 

 Messrs. Airier and Hancock's promised work on the Tunicata. 

 Two fine examples of Stylifer Turtoni were found adherent to an 

 Echinus pictus off Holy Island. And with reference to this 

 Echinus it may be remarked, that though the dredges were put 

 down, as we thought, on the very spot where we obtained, the 

 previous year, abundance of Echinus Drohachiensis, nevertheless 

 this time not one specimen of the latter species came up. There 

 must have been plenty of it within a few yards of the dredge ; 

 for the nature of the locality, almost close beneath the cliffs of 

 one of the Fern Islands, precluded the possibility of any great 

 error in this respect. 



Amongst stalk-eyed Crustacea the following deserve notice : 

 Atelecyclus heterodon, Pagurus cuanensis, Hyndmanni and ferru- 

 gineus, Crangon Allmanni, spinosus, nanus and fasciatus. Pagurus 

 ferrugineus and Crangon fasciatus are new to the district. The 

 most important Amphipoda are the following: Lysianassa Costa, 

 Anonyx Holbollii, Haploops tubicola, Ifonoculodes carinatus, West- 

 woodilla ccecula, Protomedeia Whitei, (Ediceros parvimanus, Urothoe 

 marinus, Pexamine Ycdlomensis, Calliope bidentata fundescribedj, 

 Eusirus Helvetice, Meiscladus longicatidatus, Cheirocratus mantis 

 and Unciola planipes, the two last-named being new species now 

 described by the Rev. A. M. Norman. Of Ostracoda, besides Cythere 

 eontorta and C. avena, the following new species, also described 

 by Mr. Norman, were taken : C. Iczvata, declivis, limicola, latis- 

 sima, guttata, multifora, and Cythereis Punelmensis. A new and 

 very interesting Copepod, Calanus Clausii (Brady) was taken in
