Messrs. Carpenter, Jeffreys, and Thomscn [Nov. 18, 



bottom make the same use of the sareodie substance of the Sponges and 

 Rhizopods which they there meet with *. 



79. The Mol/usca, which in the preceding Cruises usually constituted the 

 principal results of the dredgings, were here quite subordinate, as regards 

 both number and variety, to the groups already alluded to ; and the 

 difference between the Molluscan Fauna of the Cold and that of the Warm 

 area was not by any means as great as was shown in other groups. One 

 of the most interesting types which we met with was a Brachiopod found 

 living, at Station 65 in the Shetland channel, at a depth of 345 fathoms, 

 and a bottom-temperature of 30°, viz. the TerebratuJa septata of Philippi, 

 = T. septigera of Love'n. A variety of this species, from the Pliocene 

 beds of Messina, has been described and figured by Prof. Seguenza under 

 the name of JTaldheimia Peloritana ; and it is clearly the same as the 

 Waldheimia Floridana, found in the Gulf of Mexico by Pourtales, which 

 our own numerous specimens so considerably exceed in size as to show 

 that its most congenial home is in frigid water. A single specimen was 

 found of another remarkable Brachiopod,. the Platydia anomiuides ot 

 Scacchi ( or Morrisia of Davidson), hitherto supposed to be restricted to the 

 Mediterranean. Since in this case, also, the size of our specimen greatly 

 exceeds that of the Mediterranean examples of the same species, being 

 nearly double, the presumption is strong that its original home is in the 

 Boreal, perhaps even in the Arctic region. 



SO. Only a small number of Fishes were procured, but their scarcity 

 may probably have been chiefly due to the uusuitableness of the dredges 

 as a means of their capture. The few species taken have been examined 

 since our return by Mr. Couch. The list includes a new generic form 

 intermediate between Chimcera and Macrourus, which was brought up from 

 a depth of 540 fathoms in the cold area ; a new species of a genus allied to 

 Zeus ; a new Gadus approaching the common Whiting ; a new species of 

 Ophidion ; the type of a new genus near Cyclopterus ; Blennius fasciatus 

 (Bloch), new to Britain ; Ammodytes siculus ; a fine new Serranus ; a new 

 Syngnathus; with several others, which will be described in full here- 

 after. 



81 . Having obtained the requisite supplies at Lerwick, we left the harbour 

 about noon on the 31st of August, and ran southwards until we had passed 

 Sumburgh Head, when we steered towards the west , our object now being 

 to examine the southern portion of the channel between the North of 

 Scotland and the Faroe islands with the same minute attention which we 

 had previously bestowed on its northern portion. Early the next morning 

 we sounded (Station 71) in Lat. 60 3 17', Long. 2° 53', and found the 

 depth to be 103 fathoms, and the bottom-temperature 48 =, 6, the tem- 



* It seem3 worth while here calling to mind that a Pycnngonid of even yet more 

 gigantic dimensions was among the specimens obtained by what was at that time con- 

 sidered very deep dredging in Sir James Ross's Antarctic Expedition. See 'Light- 

 ning' Report, p. 173, note.
