the scientific object for which I had undertaken such a long and un- 

 comfortable voyage would probably be frustrated. 



11. "While the divers were at work under water examining the keel 

 and timbers of the ship and fixing iron plates, and the carpenters were 

 building a bulkhead at the bow, where the most dangerous leak existed, 

 some of the ofiicers went on shore trout-fishing ; and Mr. Broad 

 (the Navigating Lieutenant) most obligingly brought me specimens of 

 two very curious kinds of Crustacea from a pool of fresh water in a 

 neighbouring island, viz. A]jus glacialis and BrcmchiiJus paludosus ; the 

 Apus is allied to the king crab or Lwiulus, and consequently to the 

 extinct Trilobites. Mr. Carpenter and I had some boat-dredging in 

 shallow water. BliyncJiomlla j^sittacea and Pecten Islandicus * were here 

 the most common MoUusca ; and a living specimen of a new species of 

 Pleurotoma (P. rubescens, J.) was discovered in 10 fathoms. This last- 

 named species is described in the footnotef. 



We left Holsteinborg on Sunday the 8th of August, and did not again 

 touch land until we returned to Plymouth. I cannot omit here publicly 

 thanking Inspector Krarup Smith, and Grovernors Pencke and Lassen, 

 for the great kindness and hospitality shown by them at Godhavn, Eiten- 

 benk, and Holsteinborg. 



12. The variation of the compass is so great in these parts that the 

 ship was steered in a north-westerly direction, although she was actually 

 going south. We recrossed the arctic circle in 66° 32' JST. lat. 10th August. 

 Poggy, damp, and sunless. Thermometer 35° only. Sounded in 410 

 fathoms, took serial temperatures, and dredged. The results of this our 

 first deep-sea dredging in Davis Strait were scanty, but interesting in 

 every department of the marine Invertebrata. Among the Mollusca were 

 Eulima stenostoma and Fiisusfenestmtus, both new to Grreenland and having 



* Pecten Islandicus is excellent eating, and not inferior to P. maximus, which is 

 sold as a delicacy by our best fislimongers, 



t Tlev.Totoma ruhescens ^, Jeffr. 



Body yellowish white ; tentacles short ; eyes small, on stalks which are united with 

 the tentacles ; foot long, squarish and double-edged in front, rounded behind ; canal- 

 fold short ; operculum small, ear-shaped, and elongated. 



Shell oral, solid, opaque, of a dull hue : sculpture, rather strong, rounded but sharp 

 and curved longitudinal ribs, which on the body-whorl extend to the suture and reach 

 rather more than halfway down ; there are twelve on each of the last two whorls ; 

 the whole surface is covered with numerous fine, irregular, impressed spiral strise, 

 which cross the ribs ; the uppermost whorls are fretted : colo^ir pale purplish red : 

 spire short, ending in a somewhat abrupt and bluat point : ivhorls 5-6, convex, regu- 

 larly increasing ; the last occupies about three fifths of the shell: suture deep : mouth oval, 

 rather wide; length rather exceeding one half that of the shell: canal short, wide, 

 nearly straight: outer lip flexuous, slightly incurved, with a sharp edge : labial notch 

 shallow and indistinct, placed near the top of the body-whorl : inner lip broad, some- 

 what excavated, and polished: pillar flexuous. Length 0-35; breadth 0-125. 



One specimen only, from 10 fathoms at Holsteinborg. Unlike any Eiu'opean or 

 North-American species.
