584 * On Observations during the Voyage of H. M.S. 'Challenger? 



reptiles, and no amphibia. Of the three species o£ land-birds we only 

 saw the Thrush {Nesocichla eremita, Gould), which seems to be common 

 and very tame into all the three islands of the group. The yellow Embe- 

 riza brasiliensis, so common in the other islands, seems to have become 

 extinct in Tristan Island, or never to have been there ; for the two desti- 

 tute Germans on Inaccessible Island told me that the Tristan people had 

 tried to introduce the bird into their island, but they did not know whether 

 they had succeeded. Gallinula nesiotis is still to be found high up in 

 the hills. Several specimens of it had been sent to Capetown, and one of 

 them had been sold last year to a merchant-ship. 



16^7* October. — Landed in the morning on the lower ground of Inac- 

 cessible Island, and collected a good deal among the Phylica- shrubberies 

 on the small hill. Here we got several Curculiones, an Hemipter, a moth, 

 and many caterpillars, besides the insects already mentioned from Tristan 

 Island. The two Germans gave me their popular names for the butter- 

 flies, of which they distinguish two species (a " Fuchs " and a " Perlmut^ 

 terfalter"- — Vanessa and Argynnis). 



In the pond at the foot of the waterfall we got several specimens of an 

 Hydrobius. 



The Nesocichla and Emberiza were very common. Of Nesiotis, which 

 the Germans declared to be a smaller bird than the Tristan one (?), some 

 pairs had been seen previously on the lower ground, but they were 

 commoner on the top of the hills. 



17th October. — Collected some beetles and other animals among the 

 Phylica trees and on the corpses of dead puffins, as well as hi the nests 

 of the albatrosses . Nesocichla and Emberiza were very common ; no Nesiotis 

 was seen.
