and rattlesnakes were forwarded by express to the Zoological Park at New 

 York. 



We left Guaymas at 6 P. M., and reached Santa Catalina Island, near 

 the west side of the Gulf, at 9 o'clock of the 16th. The botanist found this 

 a rich locality, there being many large barrel cacti (Eckinocactus diguetii) 

 some of them 15 feet high. One of the largest measured seven feet .in 

 circumference. A number of skulls of porpoises (Ghbiocephalus scammoni) 

 and one of Tursiops nuuanu, a new species, were obtained on the beach 

 where fishermen had evidently been making porpoise oil. A good collection 

 of fishes and lizards was obtained. The fishes included a sea bass (Dcrma- 

 tolcpis punctatus) 30 inches long and some groupers. 



We left at noon for Santa Cruz Island a little farther south, arriving at 

 3 o'clock. Here additional skulls of porpoises were obtained on the beach 

 and a good collection was made of fishes and shore forms. 



Leaving Santa Cruz at 5 P. M., we reached La Paz (Pichilinque Bay), 

 on the morning of the 17th where the usual work of the expedition was re- 

 sumed. The following day the collecting party, including the botanist, 

 was sent by launch to Espiritu Santo Island with a tent to remain over night 

 and be picked up by the ship the next day on her way south. While the ship 

 was coaling, we again called on the officials, procured our mail and made 

 inquiries respecting the fisheries. 



On the morning of the 19th, the 'Albatross' reached Espiritu Santo, 

 arriving at 9 o'clock. The collectors came on board with one specimen of 

 the interesting black jack rabbit (Lepus insidaris) peculiar to this locality, 

 an introduced specimen having been previously secured on Pichilinque 

 Island. They obtained also wood-rats, mice, lizards, birds and plants. 

 Among the last was a new century plant (Agave roseana). We remained 

 here until noon, visiting the pearl shell propagating station, under the guid- 

 ance of the manager, Mr. Gaston Vives. Some excellent photographs of 

 this important station were secured. An account of the pearl fishery will 

 be found under another heading. 



Leaving at noon, we reached Ceralbo Island on our way down the Gulf 

 at 3 P. M. The most interesting find here was the large black and white 

 lizard (Ctenosaura hemilopha) the species obtained on San Esteban Island 

 farther up the Gulf. Seven specimens of this lizard were taken, four of 

 which exceeded two feet in length. A few fishes were also secured. 



Ceralbo is 15| miles long by about 4 miles wide, with a height of 2,477 

 feet. It lies east of La Paz Bay and is not more than five miles from the 

 nearest point on the Peninsula. 



Leaving Ceralbo at 6 P. M. we reached San Jose del Cabo on the morn- 

 ing of the 20th. Here Mr. Osburn left the ship with a collecting outfit with
