two species of amblyrhynchus, first made knowu by Darwin,) lizards, 

 birds, seals, turtles, besides a great variety of fishes, Crustacea, mol- 

 lusks, and radiates. 



" From the Galapagos we proceeded to Panama, where we arrived on 

 the 25th of June. We were detained here for three weeks, but they 

 were very profitable weeks for the collections. The loss of the greater 

 part of our dredging-apparatus between Juan Fernandez and Valparaiso 

 had indeed made dredging in deep waters impossible, but we were the 

 more industrious in collecting in shoal waters along shore and on land. 

 Our next port was Acapulco, where we arrived on the 4th of August, 

 and remained for some days. There, also, we were successful in col- 

 lecting, and not less so in Magdalena Bay, where we passed two days 

 in drawing the seine. We made no pause between Magdalena Bay and 

 San Diego, where we arrived on the 18th of August. In the Bay of San 

 Diego we added very considerably to our collections. Here, and in- 

 deed all along the coast from Valparaiso northward, we iouud many 

 specimens of cetaceans and selachians. We gathered a large number 

 of cestracions alone. 



" Leaving San Diego on the 28th of August, we reached San Francisco 

 on the 31st. Here our voyage ended, but I remained in San Francisco 

 for some weeks for tLe sake of completing collections formerly made for 

 me in this region. Both there and in Sacramento, with the aid of 

 friends, I succeeded completely in my object. 



" It would be impossible for me now to give you more than a very vague 

 and imperfect idea of the extent and value of the collections derived from 

 this voyage. Indeed, I do not fully know it as yet myself, the unpack- 

 ing being but just begun. The number of barrels and cases, however, 

 forwarded to Cambridge during the ten months of our absence was 

 265 — almost a barrel a day. It would have been simply imijossible for 

 me to collect on this scale, but for the cordial assistance 1 received from 

 the captain and officers of our ship, and, under their direction, from the 

 men, who were always cheerfully ready for the work of the seine and 

 dredge. I was also greatly indebted to Dr. Hill and Dr. White, the 

 physicists of the expedition, who, whenever not engaged in their own 

 duties, were ready to aid me in every way. I should not forget to men- 

 tion that Dr. Hill made, also, a most valuable and admirably preserved 

 collection of marine plants, gathered at every anchorage where time was 

 allowed for landing. As to the special work of the chemical and phys- 

 ical departments, under the charge of Dr. Hill, ex-president of Harvard, 

 and Dr. White, of Philadelphia, I can give you little information. You 

 could, no doubt, learn all details respecting this part of the work by 

 application to these gentlemen, or to the Superintendent of the Coast 

 Survey. 



" My own special party for zoological work consisted of Count Pourtales, 

 Dr. Steindachuer, and Mr. Blake. Count Pourtales, while sharing in all 

 the general work of the expedition, had special charge of the dredging
