208 Dr. J. Gwyn Jeffreys on the [June 15_, 



these indude two very marked forms not hitherto found in any other 

 localities, namely BJiahdopleura abyssorum, Parker, and Lituola cassis, 

 Parker, and also JSonionina Lahradorica, Parker, and Bidimina pyrula, 

 D'Orb. The Ostracoda include Gythere tuhercidata, Gr. O. Sars, C. 

 Canadensis, Gr, S. Brady, and Paradoccostoma flexuosum, Gr. S. Brady ; the 

 last of gigantic size as compared with the dimensions it attains in our 

 own seas. 



Station iVb. 1. Off Hare Island, Waigat Strait, at the entrance of 

 Baffin Bay ; 175 fathoms. 



The chief features in the dredging were the magnificent Astrophytons 

 of the two Arctic species Agassizii, Stimpson, and eucnemis, Miill. & 

 Trosch., and the abundance of luxuriantly developed Horner a lichenoides, 

 upon the branches of which were living many other very rare Polyzoa. 

 Hippomedon ahyssi (Groes), Pontoporeia femorata, Kroyer, and Amphi- 

 thopsis latipes (M. Sars) among the Amphipoda, Pallene intermedia, 

 Kroyer, Nymphon grossipes, Pabr., and N. hirtipes. Bell, among the 

 Pycnogonoidea, were the most interesting Crustacea. Ctenodiscus cris- 

 patus, E-etz., was abundant ; and the only example of Antedon Eschrichtii, 

 Miill. & Trosch., taken in the expedition occurred here. The Polyzoa 

 were many and good ; for example, Eschar a elegantula, D'Orb., Leieschara 

 suhgracile (D'Orb.), Idmonea Atlantica, Porbes, Alecto diastoporides, Xor- 

 man, Menipea arctica, Busk, and Discopora sincera, Smitt. 



Station No. 3. Lat. 69° 31' N., Long. 56° 1' W. ; 100 fathoms. 



Among the Crustacea here were the extraordinary Isopod Munnopsis 

 typica, M. Sars (which that excellent naturalist elaborately described in 

 the last work published before his lamented death*), Glauconome leucopis, 

 Kroyer, Hippomedon abyssi (Goes), and Aceros phyllonyx (M. Sars). 

 Among the Polyzoa Flustra membranaceo-truncata, Smitt, and a new 

 Lepralia, which in many respects comes near L. trispinosa, but which, 

 in addition to the acute-mandibled avicularia, has very numerous ovoid 

 avicularia ^ith rounded mandible scattered over the cells, while the 

 mouth wants the spout-like projection of the lower margin, and is 

 somewhat different in outhne : this form may be named L. Jeffreysi. 

 Among the Echinodermata were Myriotrochus Rinhii, Steenstrup, 

 Asterias Groenlandica, Stimpson, Ophioglypha Sarsii, Liitken, Ophiocten 

 sericeum (Porbes), Amphiura Sundevalli, Miill. & Trosch., and Astrophy- 

 ton eucnemis, Miill. & Trosch. The Arctic Actinian Chrondactinia mdoscc 

 (Pabr.) was also procured here, together with an undescribed Ammo- 

 thoa, which Dr. Liitken has kindly given me the means of comparing 

 and identifying with his Ammothoa arctica, Liitken, MS.
