144 REPOiiT — 1872. 



The Hydrozoa and Anuelida have not yet been detevmiued, and only a small 

 portion of the Foraminifera have been critically examined. 



The following is a brief descriptive sketch of a few of the most interesting speci- 

 mens collected. More minute details of the results of the Expedition will shortly 

 be published by the author. 



The most curious of the Foraminifera is a Margumlina, about | of an inch in 

 length, from the lirst chamber of which spinous processes project at various 

 ano-les. These vary in number in the two specimens collected, and when perfect 

 were probably as long- as the shell itself. 



Among the sponges are Grantia ciliata of 0. Fabricius (the first sponge with 

 calcareous spicules recorded from the Gulf of St. Lawrence), a fine species of 

 Polymastia, and a massive HaUchondria with retentive bihamate spicules. Among 

 the Actinozoa the most conspicuous novelty is a beautiful species of Pentiatula, 

 near to the European P. jjfio.fpJiorea, but sufficiently distinct from it, for which 

 the author proposes the name Pennatula canadensis. Upwards of forty living 

 examples were dredged in deep watsr, some of which are 8 inches long. The 

 genus is new to the American side of the Atlantic. Other interesting Ooelenterates 

 from the deep sea are a little social anemone, a species of Zoanthits, a new genus of 

 Alcyonoids near to Cornuhiria, and JEinep/ithi/a f/hmer<tta, the latter only known 

 previously from Greenland and the banks of Newfoundland. Two rare echino- 

 derms were collected : one of them is a well-known Norwegian heart urchin, the 

 Brissus fruf/ilis of Dilben and Koren, the Schizaster fra;/i/is of more modern writers : 

 the other. Prof. A. Agassiz informs the author, is the " curious Asterid allied to 

 Pterastcr" which Prof. ■ Wyville Thomson named Calveria hydrix; the name 

 has, however, been proposed for two widely dilierent species in the same journal. 

 The Canadian starfish Prof. A. Agassiz thinks may be the Solaster fitrcifer of 

 Diiben and Koren. 



No large crabs or lobsters were taken in deep water. The group is only repre- 

 sented apparently in the greater depths by a few curious arctic shrimps. In 125 

 fathoms, off Cap-Hosier lighthouse, fine specimens of Nymphon yiyanteum, Goodsir, 

 and Munnopsis typica of Sars were taken. Several living examples of a Pycno- 

 gonum, undistinguishable from the European P. Utlorale, were brought up by 

 hempen tangles from 212 fathoms. 



The deep-water Polyzoa are ^■ery interesting and curious. The most striking 

 among them are : — Defrancia luccrnaria, Sars ; Itdcpnra celluJosa, var. clouyata, 

 Smitt; Flmtra Parlcei, Busk; Picellaria ciliata, I^inu. ; and Alcyonidium gelati- 

 nosuni, Pallas. 



With the exception of a purple Pofrylliis, apparently new, the few Tunicates 

 obtained are well-known nortiiern New-England species. 



The following species of shells collected are new to the western side of the 

 Atlantic : — 



Utriculus hyalinus, Turton. 



Area pectunculoides, ScaccJii. 

 Portlandia frigida, Torell. 

 „ lucida, Lovi'H. 



Astarte, two new species. 

 Nea3ra arctica, Sats. 



,, lucida, Lov^n. < ,, Sarsii, Jeffreys. 



The following rare species were also dredged in various localities : 



Dentaliuin abyssorura, Sars. 

 Siphonodentalium vitreum, Sar^ 

 Eulima stenostoma, Jeffreys. 

 Sipho spitz bergensis, Peeve. 



Tei'ebratula caput-serpentis ? 



„ spitzbergensls, Dav. 



Pecten groenlandicus, Chcmn. 

 Ijima subauriculata. 

 Portlandia thracireformis, Storer. 

 J-)acrydium vitreum, Moller. 

 Astarte lactea. Prod. S)- Sow. 

 Macoma inflata, Stimp!;. MSS. 



Philiue quadrata, IVood. 

 Lacuna glacialis, Moller. 

 Rissoa carinata, Mighels. 

 Rissoella eburnea, Stimps. 

 Buccinum cyaneum ?, Prny. 

 ,, cili.atum, O. Fah, 



Fasciolaria ligata, Miyhels. 

 Trophon craticulatus, O. Fah. 



Three small fishes were on separate occasions taken in the dredge. Of tliese, 

 one is a small example of the Norway liaddock (Sebastes norveyicus), one a young 

 wolf fish (Anarrhichas lii2)i/s), and the other a gurnard of the genus Agonus,
