Chart of the route, with stations occupied ; showing the distribution of four of the 

 commoner species of surface Medusae, Ehopalouema velatum, Liriope tetraphylla, Cytaeis 

 vulgaris, and Aglaura hemistoma. There is no attempt made to show quantitative 

 results, the colors merely indicating the localities at which the respective species were 

 captured. A legend indicating the species to which the different colors correspond is to 

 be found on the chart itself. In the legend Cytaeis communis should read C. vulgaris. 



The heavy dotted line intersecting the lines Callao Easter island, Easter island Gala- 

 pagos, and Galapagos Maiigareva coincides with the southern limit of good trawl hauls, as 

 plotted in the General Report of the Expedition. (A. Agassiz, : 06, pi. 3°.)
