that such a system was advisable for a future identification of the 

 specimens treated of in these pages. 



In Amdrup's account of the Danmark Expedition ("Meddelelser 

 om Grønland" vol. XLI), a little is said respecting the geological 

 finds, but the present writer thinks it advisable to recapitulate what 

 was given there. The Carboniferous formations in this district were 

 observed during the course of the great sledge-journey northwards, 

 in April and May, 1907. The two sledge-expeditions, each consisting 

 of three men, which, under the command of Mylius-Erichsen and 

 Captain Koch, were to carry out the great exploring journeys to the 

 most northern of the then altogether unknown parts of East Green- 

 land, here separated from the parties that accompanied them 

 so far for the purpose of provisioning, etc. One of these provision- 

 ing parties returned on the 23 of April from the Mallemukfjæld, and 

 the other on the 26 of the same month from Sophus Müller's Naze. 

 This latter party consisted of Dr. Wegener, the meterologist of the 

 Expedition, and G. Thostrup, and was not to return direct to Dan- 

 marks Harbour, but was to carry out geological investigations in 

 Ingolfs Fjord and Dijmphna and Hekla Sounds. 



The places in Amdrup's account where the geological conditions 

 are mentioned are the following: 



P. 117. ''April 20:th Ког.н and Wegener made geological 



investigations at Mallemukfjæld and collected specimens of the car- 

 bon formation there " 



P. 118—119. "April 2A:th At Eskimo Naze Almost 



all went to work to collect either Eskimo relics, such as darts, snow- 

 knives, fragments of sledges and kaiaks, etc., or fossils, of which 

 many occurred here even in the sandstone used by the Eskimo as 

 building material. The collections were deposited in a depot at the 

 spot, to be fetched on the return journey " 



P. 119. "April 26:th Sophus Müller's Naze At this 



settlement also the sandstone was full of fossils, especially bivalves 

 and corals. In the course of half an hour a very considerable col- 

 lection had been made and deposited at the place to await their 

 return. Mylius-Erichsen, however, specially requested Koch not 

 to take the Eskimo objects, if he should arrive first at the tenting 

 place " 



The following may be quoted from the account of Captain Koch's 

 return journey: 



P. 137. "June 9:ih From Eskimo Naze they took with 



them a number of fossils deposited there by Wegener " 



On the other hand, the account does not report that, on his 

 return journey, Captain Koch carried with him any geological col-
