but it does not occur in the woods at present. He also talks of 

 the " Swartzea pennata, Jajo," which was possibly Swartzia 

 pinnata^ Willd., sometimes cultivated in Brazil. 



The animals collected by this expedition are in the British 



Museum. They include the skink, dove, tyrant, and also Thysa- 

 nodactylus lineatus^ a large lizard not known now to occur in the 

 island ; but as the expedition collected at other places, it is quite 

 possible that this specimen may have been collected elsewhere 

 and mislabelled. Mi\ Webster remained on the island a month. 



The ' Beagle' landed its crew on the island on Feb. 20, 1832, 

 and Mr. Darwin visited the Peak and made geological notes 

 upon it, and also collected a number of plants, now in the Cam- 

 bridge Museum. He says "the whole island is covered with 

 wood, but from the dryness of the climate there is no appearance 

 of luxuriance." 



In 1871, H.M.S ' Bristol ' visited the island to take some alti- 

 tudes, and Dr. Rattray published an account of the geology in the 

 Geological Society's Quarterly Journal, vol. xxviii. pp. 31-34, and 

 a popular account of the island in the Geographical Society's 

 Journal. Of these it will be sufficient to say that the geological 

 account and map are erroneous and misleading — the phonolite 

 being spoken of throughout as granite, and the so-called granite 

 being marked on spots where basalt only occurs, while " tertiary 

 conglomerates " are recorded from various spots and correlated 

 with those on the mainland of Brazil. What was intended by 

 these " tertiary conglomerates " is not clear, but probably masses 

 of basaltic beach-pebbles cemented together by gypsum, which 

 occur in some at least of the spots where the tertiary conglo- 

 merates were found. 



In Sept. 1873, H.M.S. ' Challenger' arrived at the island with 

 intention of exploring it, but being unarmed with the requisite 

 authority, were refused permission. Prof. Moseley, however, 

 succeeded in obtaining a few plants, both from the main island 

 and from St. Michael's Mount, which were described and figured 

 in the Voyage of the ' Challenger ' Eeport, Botany, pt. ii., by 

 Mr. Hemsley*. The officers of the 'Challenger' also took 

 soundings at various distances from the ship, and dredged at 

 some little distance from it. The animals obtained are in the 

 British Museum ; the plants were divided between that institu-
