All along the Mourmane coast as far as tlie Varanger Fiord, 

 P. lapilliis occurs in suitable localities, where it is quite common. 

 Specially may be particularized : Gavrilovo (69° 20' jST., 36° E.), 

 Lodenaia, Teriberka (69° 20' JST., 35° 10' E.), the port and island of 

 Jekaterinskaia Gavang in the Kola Fiord (all in Coll. A. H. C). 

 Pfelfer (99) records it from leretik Islands, Port AVladimir (69° 40' N.), 

 and the Mourmane coast generally. In East Finmark it is recorded 

 from Vadso in the Varanger Fiord (Norman 91, de Guerne 29, Coll. 

 A. H. C), with the var. tinbricata, Lam., and in North Finmark from 

 the Porsanger Fiord (Friele 38, Coll. A. H. C). 



The general facies of many specimens from the extreme north is 

 very characteristic, and would amply warrant those who are fond of 

 naming varieties in applying to them the name of var. borealis. The 

 shell is comparatively thin, long and rather narrow, spire elevated, 

 mouth very long oval, outer lip scarcely at all thickened, sculpture 

 a number of raised concentric rings, which in some cases tend to 

 disappear altogether, colour light to very dark brown. The extreme 

 form of this variety occurs in the Kola Fiord and on the Mourmane 

 coast; specimens from Vadsfi and the Porsanger Fiord are similar in 

 shape and more compact in structure. The same form of shell occurs 

 in North- West Norway at Tromsci (Coll. A. H. C.) and at least as far 

 south as Lodingen (68° 30' N.), where it is much more massive and 

 solid, one specimen measuring over 1-625 in. in length. 



P. Idpillus is common on the Norwegian coasts from the North 

 Cape (M. Sars 106, Loven 72) to the Naze, and exhibits many of the 

 same variations of form which are to be observed on our own coasts. 

 Specimens from Troudhjem recall a form from Newquay or South 

 Wales, from Aalesund a form common on the West of Scotland, from 

 Finsnes a form from Loch Swilly. It is noted from the Lofoden Islands 

 (G. 0. Sars 105) and from Bergen (Lamy 64), and is found in every 

 suitable locality on the northern shores of the Skager Kak up to the 

 outer waters of the Christiania Fiord, becoming more scarce as we 

 move north. Asbjonisen (5) distinctly states that it is not found in 

 the narrow waters of the fiord, but only in the open sea, naming such 

 places as Randoer, Bollaererae, and Faerder Islands, where it occurs, 

 seldom living, at a depth of 10-20 fathoms. Jeffreys (52), for 

 instance, did not get it at Drcibak. On the south-west coast of 

 Sweden, Malm (79) records it from the Vadero Islands, and, with Theel 

 (116), also from Christineberg, on the western shore of Bliibergsholm, 

 in liohusljin. But a very short distance further south it becomes 

 scarce, and Malm (80) records that near Gciteborg it occurs only on 

 the outer side of Vinga Islands, where it was so rare that he was only 

 able to collect one single living specimen, but in the trawl he got a few 

 dead shells. The British Museum possesses two specimens labelled 

 "Coast of Sweden", which were dredged by Dr. Thuden and 

 presented by him on October 13th, 1863. The shells are small, not 

 quite mature, the largest measuring -875 inch in length, surface 

 slightly imbricate, concentrically corded with raised lines, spire 

 prominent, colour dirty white. 



In the Southern Kattegat, Lilljeborg (68) recorded P. lapillus from
