Natural History of East F'lnmarlc. 355 



Scalaria ohtusicosfata (S. Wood), G, 0. Sars. 



Lceocochlis granosa, Wood. 



Cerethiopsis costulata, Moll. Lang Fiord, 30 fathoms ; Bog Fiord, 

 20-30 fathoms. 



Nexvtoniella metula, Loven. 



Turritellopsis acicula, Stimpson. Vadso and Yaranger Fiord, in 

 shallow water to 15 fathoms. 



Trichotropis horealis, Brod. & Sow. Lang and Bog Fiords and 

 also Lofoten, down to 80 fathoms. 



conica, Moll. 



Littorina littorea, Linn. Vadso, Lang Fiord, &c. 



riidis, Maton, var. grcenlandica, Moll. Extremely abundant. 



When found near or quite at high-water mark on rocks it is 

 of smaller size than when living lower down, and at the same 

 time more richly coloured. The colour is very variable : pure 

 white ; white banded with black or brick-red ; grey ; grey 

 mottled with dispersed yellow spots ; black ; black banded 

 with white. A form taken in Bog Fiord has the spire more 

 elevated than usual, and corresponds to our English var. 

 tenehrosa. The surface of the shell is usually smooth or 

 sculptured only with slightly elevated spiral ridges. At Vardii, 

 however, a large variety occurs which is girt with strong spiral 

 ribs, and is quite indistinguishable from Littorina sitchundj 

 Philippi, from Vancouver and the Behring Sea. It is figured 

 by Sars, Moll. B,eg. Arct. Norv. pi. ix. fig. 10. 



* obtusata, Linn. Occurs of quite the normal British form and 



appearance at Svolvser, Lofoten. In East Finmark it gives 

 place to the following very remarkable varieties : — 



var. paUiata, Say, Sars, pi. ix. fig. 9. Tromso, Vardo, 

 Vadso, &c. 



forma elatior, Sars, pi. xxi. fig. 19, has the spire so much 

 elevated that it has the shape of L. rudis ; it occurs between 

 tide-marks not far from low-water mark at Vardo. 



forma coarctata, Sars, pi. xxi. fig. 20. This extraordinary 

 shell occurs with the last at Vardo, and is indeed an extreme 

 form of forma elatior, with which, and Avith jjalliata of 

 ordinary form but of large size, it is found. 



Lacuna p)(dlidula, Da Costa. Tide-marks, Vadso. 



divaricata, Fabr., var. solidula, Loven. Vadso and Bog and 



Klosterelv Fiords. 



var. frigida, Love'n. Xlosterelv Fiord. In both these 

 varieties the specimens have been compared with cotypes 

 received from the late Professor Loven. 



SJcenea planorhis, Fabr. Vadso ; Klosterelv Fiord and Svolva^r. 



Hydrohia mimita, Totten.
