390 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



The serial numbers of Albatross dredginjjj and hydrographic slat ions, 

 the former beginning at 2001 and the latter at 1, were carried without 

 change or duplication from 1883 until 1899, when the series "A. A." 

 (A. Agassiz) was added temporaril5\ During the cruise through the 

 tropical Pacific all of the specimens received "A. A." numbers; these 

 are shown, both in the dredging and hydrographic series, in columns 

 parallel with the regular serial numbers, which are still continued. 



The records of tow-net stations — not kept systematically during the 

 earlier work of the Albatross — are presented for the period from 1887 

 to 1900 only. The numbers identifying them are not, unfortunately, 

 continuous from year to year. They are frequently identical with the 

 nearest dredging or hydrograpliic stations. 



The oceanic areas explored by the Albatross have been platted upon 

 the accompanying series of charts. As the vessel returned to certain 

 regions year after year, it will be noticed that the serial numbers of 

 the dredging stations are much vscattered. Two of the maps show the 

 positions of dredging stations in depths greater than 100 fathoms, the 

 dredgings of less than 100 fathoms being shown on a separate map. 



A list of dredging stations, by Sanderson Smith, published in 1888, 

 contains, with earlier dredging records, several maps which show the 

 positions of dredging stations. It is numbered 58 in the accompanying 

 catalog of publications. Other maps showing the positions of Alba- 

 tross dredging and hj^drogi'aphic stations will be found in the papers 

 numbered 52, 59, 71, 86, 87, 89, 117, 159, and 198. The most important 

 of these, with respect to deep-sea dredging, is No. 86 (same map as 

 in No. 198), showing the positions of stations from Panama to the Gulf 

 of California. 



The catalog of papers relating wholly or in part to the work of the 

 Albatross numbers nearly 300 titles, including those in preparation. 

 It is annotated' briefly, the names of new genera and species described 

 in each paper being given in full. 



The yearly reports of the commanding officer of the Albatross con- 

 tain accounts of the daily movements of the vessel. They pi'esent not 

 only the dredging and hydrographic data, but the records on ocean 

 temperatures, specific gravities, and other observations made on board, 

 with many notes on the general character of dredge hauls. Reference 

 should be made to these reports^ for many details respecting the work 

 of the Albatross and for numerous records not presented in this jjaper. 



Special papers on the results of Albatross investigations have been 

 published in the reports and bulletins of the U. S. Fish Commission, 

 the proceedings, bulletins, and reports of the IJ. S. National Museum, 

 the bulletins and memoirs of the Museum of Comparative Zoology, the 

 proceedings of the Biological Society of Washington, the transactions 

 of the Connecticut Academy of Arts and Sciences, and in the American 

 Journal of Science. In the proceedings of the U. S. National Museum 



Numbers U, 35, 45, 46, 52, 53, 70, 87, 99, 132, 159, 160, 185, 190.
