218 CKUISE OF THE NEPTUNE 



black shale containing Monograptus sp. and Leperditia cfr. 

 phaseolus is a bed of fragmentary limestone with Favosites, 

 Strophomena cfr. pecten, Atrypa reticularis, Pterniea cfr. 

 Sowerbyi. From a locality in Gaasef jord, on the same horizon, 

 were taken Favosites cfr. Hisingeri, Favosites Gothlandicus, 

 Thecia Swinderenana, Spirifer elevatus, Spirifer cfr. crispus, 

 Strophomena corrugatella, Dav., Pterinea sp. According to 

 these, the period of this upper part of Series B should be Lud- 

 low. The thickness of the series is about 1,000 feet.' 



' In Hell Gate, as well as in Gaasef jord, these strata are over- 

 laid by Series C ; in its lower parts consisting of interstratified 

 light and dark marl schists, which are somewhat sandy, while in 

 its upper part appear pure quartz-sandstone beds and argilla- 

 ceous sandstone. The collective thickness of these strata is about 

 1,000 feet in Gaasefjord, while in Hell Gate it is probably 

 somewhat greater. ]^o fossils were found in this series.' 



' At the base of the high cliffs at Indra Eide and Borgen 

 appears Series C. In both of these places it is overlain by a 

 dark limestone and black shale, partially fossiliferous. This 

 dark limestone and shale are the lowest layers in a series of 

 strata at least 1,500 feet in thickness, Series D, which appears 

 in the profiles on both sides of Gaasefjord, from Borgen to the 

 foot of Vargtoppen (Wolf Top), and from Indre Eide to 

 Skrabdalen.' , 



' In Series Da occurs Atrypa reticularis in great quantities, 

 but little else. On the other hand, there are preliminary deter- 

 mined in Db about fifty-five species, of which may be men- 

 tioned: Favosites sp div., Columnaria sp., Cyathophyllum sp. 

 cfr. hexagonum, Recaptaculites sp., Fenestella sp., Homalono- 

 tus sp., Burmeisteria sp., Dechenella sp., Proetus sp., Orthis 

 striatula, Leptaena sp., Strophomena, Streptorhyncus, Atrypa 

 reticularis, aspera; Rhynchonella (Pugnax) cfr. reniformis, 

 pugnus, Productus cfr. prolongus, Spirifer of the Verneuilli
