NO. 1 FRASER: SCIENTIFIC WORK, VELERO III, EASTERN PACIFIC 5 



at Coquimbo, Calderas, Mexillones, Callao, and Puna. In 1884 the 

 months of January and February were spent in the Gulf of Panama and 

 in March the Galapagos Islands were visited. An extensive list of the 

 Crustacea collected appears in the Bulletin of the Nature Society of 

 Naples for 1889. 



In the early months of 1888 — January to May — the United States 

 Fish Commission Steamer Albatross, Lieutenant Z. L. Tanner command- 

 ing, with Charles H. Townsend on board, made a cruise northward from 

 the Strait of Magellan to Panama, to the Galapagos Islands, to Acapulco, 

 Mexico, into the Gulf of California, and along the coast of Lower Cali- 

 fornia, collecting at several stations in the Galapagos, and north of Aca- 

 pulco, en route. Much of the collecting was done with the beam trawl 

 in shallow water (as little as 5% fathoms). There was much shore and 

 land collecting. The dredge was used for only eight hauls. An account of 

 the cruise by Lieutenant Commander Tanner appeared in the Commis- 

 sioner's Report, United States Fish Commission for 1887, published in 

 1891. 



Again in 1889 — February to April — the Albatross, Lieutenant Z. L. 

 Tanner commanding, with C. H. Townsend and C. H. Gilbert on board, 

 did some exploring in this general region. The route lay south from San 

 Diego along the west coast of Lower California, out to the Revilla 

 Gigedo Islands, back to Cape San Lucas, into the Gulf of California, 

 and back to San Diego via the west coast of Lower California. Here 

 again the beam trawl was in general use in water less than 100 fathoms. 

 Very little dredging was done. Fish made up an important part of most 

 of the catches. The Report of Commander Tanner appeared in the same 

 publication in 1892. 



In 1891 marine investigation on the Albatross was in charge of Alex- 

 ander Agassiz, with C. H. Townsend assisting, and Lieutenant Z. L. 

 Tanner in command of the ship. Operations were carried on off the west 

 coast of Central America, the Galapagos Islands, the west coast of Mexi- 

 co, and the Gulf of California. This time much more dredging was done, 

 but nearly all in deep water; out of the 100 stations, only 8 were in less 

 than 100 fathoms, and none was in less than 50 fathoms. Pelagic collect- 

 ing occupied much time, and numerous observations were made on topog- 

 raphy, currents, temperatures, specific gravity, and bottom configuration. 

 Agassiz gave a general sketch of the Expedition in the Bulletin of the 

 Museum of Comparative Zoology, Harvard, XXIII, 1891, and Com- 

 mander Tanner's Report appeared in 1893.
