6 THEEL, NORTHERN AND ARCTIC INVERTEBRATES. II. TRIAPULIDS, ECHIURIOS ETC. 



hand the localities under the head of »Distribution in general» are only references 

 from the literature in order to communicate an idea of the general distribution of 

 the aninials in question. 



With regard to the abbreviations of the names of the museums, where each 

 specimen is preserved, or of those of the expeditions, voyages or journeys, during 

 which the animals have been collected, I refer to my former report, 1 page 6 and 

 pages 23 to 49. 



Respecting the synonym y I only notice such cases where other views do not 

 agree with my own. Consequently I have mostly confined myself to referring to the 

 works in which the animals were described for the first time. 



List of Memoirs referred to. 



The following list presents an enumeration of the most important papers referred 

 to in the present account. Its extent is mainly due to my desire of giving a truthful 

 view of the »General Distribution» of the animals.
