1898-1902. No. 32.] FOSSIL FAUNAS FROM SERIES B. 5 



kap", at about 76 N. L. The scanty fossil remains are contained partly 

 in a brownish limestone, partly in yellowish-grey coarse and massive 

 dolomites in which only the interior moulds of the fossils can be seen. 

 They are the following: 



Strophonella cf. euglypha, His. 



An incomplete specimen of Strophonella, embedded in a piece of 

 brown limestone agrees, especially as to the character of the surface 

 (5 8 faint lines between very conspicuous, strong ones), completely with 

 Strophonella euglypha His. while the form seems to differ a little 

 in that the valves show a relatively larger flat (for the dorsal) or faintly 

 convex (for the ventral) posterior portion, a relatively narrower marginal 

 curved and here very strongly curved one while in S. euplypha the 

 curved portion, which bends at a more obtuse angle, is very large, 

 leaving a relatively smaller flat portion near the hinge-line. 



As, however, the entire form cannot be seen from the specimen in 

 question I will refrain from any further consideration. 



Conchidium arcticum nov. sp. 

 PI. VI, fig. 5-7. 



In a massive coarse dolomitic rock a great number of internal casts 

 of a pentameroid brachiopod occur. They are all, however, very frag- 

 mentary, not a single one showing more than a small part of the entire 

 form. Yet judging from all the various pieces we are able to obtain an 

 idea of the different characters of the fossil. 



The shell is of medium size, greatest length observed or judged from the 

 fragmentary pieces, 5 5.5cm., greatest width about the same. The ventral 

 valve is moderately curved, greatest in the region of the beak. The sep- 

 tum is comparatively short, only about one third of the length of shell. The 

 dorsal valve is very slightly convex, one specimen with preserved beak 

 showing two short septa. Some of the moulds have a well marked radi- 

 ating striation of the surface. 



The form here mentioned shows several characteristics that disting- 

 uishes it from others and gives it a specific value even if all the 

 characters are not known. It differs from all other Conchidium species 

 known to me by being relatively very slightly convex, and by the shortness 

 of the septum in the ventral valve. In these respects it seems also to 

 differ decidedly from the Conchidium-lovm described by SALTER from 

 Cornwallis Island in the Arctic Archipelago (see Sutherlands Journal, 

 Appendix, p. 225, pi. 5, figs. 9 10), a form that a priori might be con- 

 sidered identical.
