DREDGING ON THE COASTS OF NORTHUMBERLAND AND DURHAM. 189 



Deep-sea Dredging on the Coasts of Northumberland and Durham, 

 in 1864. Reported by George S. Brady. 



The following Heport is intended to embrace notices only of the more inter- 

 esting captures of the present year. Next year wo hope to be able to lay 

 before the section a general account of the results which have been obtained 

 during the three years in which our dredging has been assisted by the grants 

 of the British Association. 



In the course of the summer, eight days have been spent in dredging — hvo 

 of these on the Durham coast, and six off the northern shores of Northumber- 

 land. The weather, on the whole, was good, or at least such as not to put a 

 stop to our operations, except during the two days spent on the Durham 

 coast, on both of which we were unfortunately driven into harboui' by violent 

 gales rising suddenly and unespectedlj\ 



The Mollusca obtained this year are very poor, and afford little to remark 

 upon, the only species new to the district being Chiton alius, L., of which a 

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

 Ascidians taken on the Durham coast require further examination. Two fine 

 examples of Stylifer Turtoni were dredged off Holy Island, adherent to an 

 Echinus pictus. With reference to this species, it maybe mentioned that, 

 though the dredges were put down, as we thought, on the very spot where we 

 obtained, last year, abundance oi Echinus neglect as (in some cases with Sty lifers 

 attached), this time not one specimen of the Echinus 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 Parne Islands, 

 precluded the possibility of any great error in this respect. 



Amongst stalk-eyedCmstacea the followingdeservenotice: — Atelecyclus hete- 

 roclon, Pagurus cuanensis, P.Hgndmanni, and P. ferrugineus, C'rangon AJlmani , 

 C'.S2)inosus,C. nanus, and C'.fasciatus. Pagurus ferrugineiis andCrangonf ascia- 

 tus are new to the district. The most important Amphipoda are the following : 

 — Lysianassa Gostce, Anonyx Solbdllii, IJaploops tuhicola, Monocuiocles cari- 

 natus, Westwoodilla ccecula, Protomedeia Whitei, GEdiceros parvimanus, Urothoe 

 marinus, Dexamine vedlomensis, Ccdliope hidentata (undescribed), Eusirus Uel- 

 vetice, Heiscladus longieaudatus, Cheirocratus Mantis and Unciolaplanipes, the 

 two last named being new species, descriptions of which, by the Eev. A. M. 

 Norman, are appended to this Report. Of Ostracoda, besides Cythere contortcc 

 and C. avena, the following new species, also described by Mr. Norman, were 

 taken : — Cythere latissima, C. guttata, C. multifora, C. Icevata, C. declivis, C. 

 Bradii, Cythereis dunelmensis, and C. limicola. A new Pycnogon, Nymphon 

 ruber, Hodge, was got on the Durham coast, and is described in the Appen- 

 dix. Thirty-two species of Echinodermata were obtained, and amongst them 

 several species of great interest. Off Dunstanbro' were taken three speci- 

 mens oi Antedon rosaceus, a very rarely noticed inhabitant of our district, and 

 several remarkably fine examples of Ophiopholis aculeata. A small Echinus 

 exhibited by Mr. Norman at the Manchester Meeting of the British Associ- 

 ation, and called by him E. neglectus, var. /3, was taken abundantly. This, 

 however, has claims to be regarded as a distinct species, and will be described 

 by Mr. Norman from his Shetland specimens under the name of Echinus 

 pictus. A single fine specimen of Evhinocardiimi pennatijidum, Norman*, 

 was dredged off Holy Island. This is the more interesting as the specimen 



* This is the sjiecies described by the late Mr. Barrett from Shetland under the name 

 of Amphidetus gihhosus, Agassiz (Ann. & Mag. Nat. Hist. 2nd ser. vol. six. p. 33, pi. 7. 

 fig. 2). It is not, however, Agassiz's species.
