Dr. J. Gwyn Jeffi'eys on the 



[June 15;, 



Tow-net. 



In the tow-net in Lat. 52° 33' N., Long. 26° 44' W., in the North 

 Atlantic, the very rare PasipJicea tarda, Kroyer, was taken. The same 

 mode of collecting also produced Nautilograj>sus jpelagicus, Eoux, Idotea 

 rohusta, Kroyer, Themisto lihdlula (Mandt), Parathemisto com^pressa (Groes), 

 and Tauria medusarum (Kroyer), together with many Copepoda, a Cam- 

 panularian, Lepralia hyalina, many Diotomacea, &c. In Davis Strait 

 were similarly taken Themisto lihellula (Mandt), Themisto hispinosa, 

 Boeck, Tauria medusarum (Kro3^er), and Onesimus littoralis (Kroyer), 

 together with the beautifully spinose Copepod recently figured by Buchholz, 

 in the Eeport of the German jN'orth-Pole Expedition, under the name 

 " Cleta mimiticoniis, Miiller"*. It is, however, most certainly not the 

 species described by ILliUer or Baird ; and I would therefore propose 

 for this very distinct Arctic form the name Cleta horrida. 



Holsteinhorg Harbour, 7-35 fathoms. 



Holsteinborg Harbour produced a rich harvest of Arctic forms. The 

 Crustacea included the great spider crab of the Greenland seas, Ohione- 

 cetes Ojpilio (Fabr.), the fine northern shrimps Crangon horeas (Phipps) 

 ^iTL^iArgis Lar (Owen), the rare Amphipods Onchomene minuta (Kroyer), 

 Byhlis Gaimardi (Kroyer), (Ediceros lynceus, M. Sars, and horealis, A. 

 Boeck, Protogeneia incrmis (Kroyer), Antonoe macronyx, Bruzelius, and 

 Photis Beinhardtii, Kroyer, together with many species familiar to us off 

 the British coasts. The Ostracode Brady cinetus Brenda (Baii'd) was in 

 extraordinary abundance, along with Cytheridea papulosa, Bosquet, /Sc^g^'o- 

 chilus contortus (Xorman), Xestoleheris depressa, G. 0. Sars, Cythei^ura 

 undata, Sars, Cythere tuherculata, emargiiiata, lutea, and other species. 

 Most of the specially Greenlandic Echinodermata occurred here. The 

 Holothurians Orcula Bai^thii, Trosch. (? or new), Cucumaria minuta, 

 Eabr., and calcigera, Agassiz, Psolus Fabricii, Diib. and Keren, Chirodota 

 Iceve, Eabr., and Myriotrochus Biiikii, Steenstrup, the Ophiuridan Ojohio- 

 glypha nodosa, Liitken, and the Asteridan Asterias alhula, Stimpson, were 

 associated with forms which are also European. Here, too, were such 

 interesting Polyzoa as : — Leieschara suhgracile (D'Orb.) ; Celleporaria in- 

 crassata, Lamk. ; Bugula Murrayana, Bean, both the typical form and 

 that named by Packard from the coast of Labrador {B. fruticosa) and 

 by Loven from Einmark {B. quadridentata). Our common Lepralia 

 ventricosa, Hassall, seems to be also the most abundant Greenland 

 Lepralian ; it was found here and in all the other inshore dredg- 

 ings. A new Cellepora in Holsteinborg Harbour and other Greenland 

 localities had been previously sent to me by Mr. Whiteaves from the 

 Eiver St. Lawrence, where it was procured in the dredgings of the
