Among the very extensive collections made during the past eight 

 years by the U. S. Commission of Fish and Fisheries, under the direc- 

 tion of Professor Baird, there are still many species not recorded as 

 American in any of the reports hitherto published ; most of these are 

 well-known Arctic or Northern European species, but others are still 

 nndescribed. As the final reports on the different groups will require a 

 long time for their completion, owing to the vast number of specimens 

 to be examined from more than a thousand localities, it has been thought 

 desirable to record some of the more important additions to the fauna, 

 without further delay.* More detailed descriptions and numerous fig- 

 ures will be published in the final reports, together with the details of 

 their geographical distribution. All the species included in the follow- 

 ing list, unless otherwise stated, have been collected by the U. S. Fish 

 Commission. 



"Many species have also been recorded in various articles in the American Journal 

 of Science and Arts, during several years past. See, also, an important paper on the 

 Podophthalmous Crustacea, by Professor S. I. Smith, and one on the Pycnogonida, by 

 E. B. Wilson, in the Trans. Conn. Academy, vol. v, 1879.
