 the Lisbon Museum. 



This interesting little bat, which I have named in honour 

 of Senhor A. F. de Seabra, C.M.Z.S., of the Lisbon Museum,

 and the large antero-internal cusp on ji/. Its general appear- 

 ance is rather that of a Pipistrellus than a Myotis.

[Plate VII.] 



The genus Nymphon, and indeed all the Nymphonldse, are 

 of rare occurrence in the Pacific. The total number of 

 Pycnogonida recorded there is not yet very large, and the 

 JS^ymplions included are relatively very few. From the 

 South Pacific two deep-water forms were brought home by 

 the ' Challenger,' viz. JSymijhoa longicollum^ Hoek, and 

 Nymphon procerum, Hoek. Ortmann describes one well- 

 defined species, Nymphon japonicum, from Japan; and from 

 the China Sea a more doubtful one, Ny?nphon longiceps, has 

 been described by Grube. Two are recorded from Australia — 

 ]S. longicowa, Hoek, and N. cequicliyitatum, Hasvvell. If we 

 then exclude those found from the Straits of Magellan south-
